Safety Action

Recommendations

As a result of the investigation into this occurrence, the Bureau of Air Safety Investigation issued the following recommendations:

IR970014

"The Bureau of Air Safety Investigation recommends that Airservices Australia review the requirements detailed in AIP Supplement H73/96, (10 October 1996) Simultaneous Opposite Direction Parallel Runway Operations Sydney (KSA) and:

  1. develop a SID which incorporates a standard left hand turn after take-off, and tracks the departing aircraft through the heads of Botany Bay in accordance with accepted separation and noise-abatement procedures,
  2. have the departing aircraft remain on tower frequency until the assigned turn has been completed, and
  3. develop a pilot aid for inclusion in departure and approach procedures (DAP) East. This chart should depict the expected flight path of aircraft departing and arriving under SODPROPS, and could be similar to the pilot-aid (Issue 1, 14 September 1995), located in DAP East, advising pilots about independent visual approaches at Sydney Airport."

Response from Airservices Australia received 4 March 1997:

"BASI has made three recommendations arising from Occurrence 9700052

Airservices has recently conducted a post implementation review (PIR) into SODPROPS at Sydney. Specific action undertaken by Airservices to address the BASI recommendations is as follows:

  1. An appropriate SID will be developed which will be standard for all departures from Rwy 16L (not specific to SODPROPS). Until then the RADAR 6 departure with specific headings will continue to be used.

    The BOTANY BAY HEADS Visual departure is no longer considered practical for jet aircraft owing to the difficulty in navigating to the Heads with high body angles and the possibility of entering cloud above 3000 feet prior to reaching the Heads.

  2. An instruction has been issued requiring ADCs to instruct departing aircraft under SODPROPS to remain on Tower frequency until established in the appropriate left turn.
  3. The recommendation to produce a pilot aid for inclusion into DAP (East) has been referred to CASA Flying Operations Branch for consideration/action.

While supporting these recommendations, Airservices is concerned that the report does not address the principle causal factor of the occurrence, namely flight crew error.

No reference is made to the following factors:

The assigned heading was correctly read back by the pilot but not entered into the FMS;

The pilot called departures radar at the appropriate time but failed to read back the assigned heading;

The use of FMS below the LSALT."

Response classification: Closed-Accepted

Response received from the Civil Aviation Safety Authority 22 April 1997:

"I refer to BASI Interim Recommendation IR 970014 addressed to Airservices Australia concerning Simultaneous Opposite Direction Parallel Runway Operations (SODPROPS) at KSA Sydney. The following comments are provided from a CASA perspective.

The first point of the recommendation is that "a SID be developed which incorporates a standard left hand turn after take-off and tracks through the heads of Botany Bay in accordance with accepted separation and noise abatement procedures". The SODPROPS standard is a visual standard and obviously the last line in separation would be the visual element. The ATC procedures specified in the local instruction indicated that a Botany Bay visual departure should be issued to departing aircraft. CASA believes there is no point in developing a Standard Instrument Departure (SID) for a visual procedure, in fact it could stop pilots from looking outside.

The second point is that the departing aircraft should remain on the tower frequency until the departure turn has been completed. Airservices Australia have since implemented this.

Finally, it is recommended that a pilot aid on SODPROPS be developed. This is probably worthy of consideration but CASA believes that AIP SUP H73/96 may require amending to specifically indicate a section on departing aircraft. Other than a reference in the standard section to course divergence there is no specific indication regarding aircraft departure requirements."

Response classification: Closed-Accepted

R970150

"The Bureau of Air Safety Investigation recommends that Airservices Australia conduct a comprehensive systems safety analysis of simultaneous opposite direction parallel runway operations (SODPROPS)."

The Bureau also made the following recommendation (R970151) to the Civil Aviation Safety Authority:

"The Bureau of Air Safety Investigation recommends that the Civil Aviation Safety Authority review the Operational Standard "Simultaneous Opposite Direction Operations" to ensure that it provides an acceptable level of safety."

Response received from Airservices Australia 1 December 1997:

"I am writing in response to your occurrence report and the associated recommendation that Airservices "conduct a comprehensive systems safety analysis of simultaneous opposite direction parallel runway operations (SODPROPS).

In addressing this recommendation, I commissioned a team to conduct an independent analysis of the SODPROPS procedure itself and the analysis that was conducted prior to the implementation of the procedure at Sydney Airport. This team comprised representatives from ATS' Safety and Quality Management Branch, [and] ATC specialists from Sydney and Brisbane. The team was assisted by expert support from CASA and the major domestic airlines.

In essence, the analysis team has produced a Safety Case (copy enclosed) addressing the safety issues identified by the original SODPROPS implementation team. This Safety Case has been augmented by a Fault Tree Analysis of the risk of failure of the SODPROPS procedure.

I must emphasise that the bulk of the analysis presented in the SODPROPS Safety Case reflects the extensive hazard analysis and risk mitigation work that was done by the implementation team prior to the implementation of SODPROPS.

Whilst it can be said that the data was not collated into a concise document (for which CASA and Airservices now advocate a Safety Case), the data was available in relevant files within the Sydney management system at the time of the BASI investigation.

The data used in this report was available in relevant files within the Sydney management system at the time of the BASI investigation.

The Fault Tree Analysis was compiled using probability data on human performance and on historical incident data. The SODPROPS Safety Case provides the necessary assurance that SODPROPS is being operated at an acceptable level of safety."

Response classification: Open

R970151

"The Bureau of Air Safety Investigation recommends that the Civil Aviation Safety Authority review the Operational Standard "Simultaneous Opposite Direction Operations" to ensure that it provides an acceptable level of safety."

The Bureau also made the following recommendation (R970150) to Airservices Australia:

"The Bureau of Air Safety Investigation recommends that Airservices Australia conduct a comprehensive systems safety analysis of simultaneous opposite direction parallel runway operations (SODPROPS)."

Response received from the Civil Aviation Safety Authority 27 November 1997:

"I refer to your letter dated 1 October 1997 reference BS/970061 regarding Recommendation R970151.

CASA has reviewed the Operational Standard "Simultaneous Opposite Direction Operations" as you have recommended. Following Occurrence 9700052 on 5 January 1997 the instructions in AIP OPS paragraph 19.4 were changed by NOTAM to require pilots to remain on Tower frequency until instructed to change, thus enabling Tower to correct the kind of confusion evident during the occurrence. The amendment will be correctly inserted into the AIP OPS text by AIP Amendment List 20, effective 4 December 1997.

Given the change to procedures our conclusion is that the standard expressed in the CASA Manual of Operational Standards (MOS) Part 3 Chapter 5.9 is adequate.

The MOS standard will be further reviewed in the light of any study which may be undertaken by Airservices in response to your recommendation R970150."

Response classification: Open

Following the provision of the SODPROPS safety case the Bureau elected to have the document reviewed by an independent consultant with international experience in aviation risk management practices and procedures. The intent of the review was to ascertain whether the safety case undertaken by Airservices was a comprehensive safety case and whether it had adequately demonstrated that SODPROPS could be conducted at a reasonable level of safety.

The review of the safety case was conducted in the last week of March 1998. On receipt of the consultant's report it will be reviewed and any further action by the Bureau will be subject to the findings of the report.

Factual Information

History of SODPROPS

The Civil Aviation Safety Authority (CASA) adapted a US Federal Aviation Administration (FAA) air traffic control spacing and sequencing standard (FAA 7110.65J) and incorporated it into the CASA Manual of Operational Standards in November 1994. The FAA standard was used by the Parallel Runway Standards Evaluation Group to develop a procedure for Australian use. This group comprised regulatory and air traffic services elements of the then Civil Aviation Authority along with other members of the aviation industry. The FAA standard was modified by adding a requirement that the departure runway course must diverge 15 degrees away from the approach course to the opposite direction runway.

The modified FAA standard was introduced into service at Sydney airport together with other changes identified as being able to meet government policies in relation to operations and noise abatement procedures at that airport. Airservices, which was responsible for Australian airspace management from 1 July 1995, planned to commence SODPROPS on 19 October 1996. Officers from Airservices organised an industry seminar for 26 September 1996 to discuss the proposed new traffic management procedures associated with SODPROPS and with the use of runway 34R for departures. At this seminar several participants questioned the extent of risk analysis that had been conducted to ensure that SODPROPS provided adequate levels of safety during all operations.

On 10 October 1996, a senior officer from Airservices wrote to CASA, seeking confirmation that the standard governing the use of SODPROPS was available for use without impediments to its application. In response to this query, a senior CASA officer replied that there was no impediment to the use of the standard, but reminded Airservices that "the safety and change management standards for Airservices require you to analyse the risks associated with the changes to ensure that unacceptable hazards are eliminated before the change is completed".

During a meeting with CASA representatives on 15 October 1996, senior Airservices officers advised that "it [Airservices] had completed a formal change process, including safety analysis, hazard analysis, training, etc. and that all risks had had correction procedures put in place".

On 17 October 1996, an Airservices officer from Sydney wrote to a domestic operator and supplied details of risk analysis conducted for the implementation of SODPROPS. This letter advised that the following three risk categories had been examined:

- "approach track keeping and associated flight crew or ATC blunders";

- "departure procedure compliance, engine failure or other aircraft malfunction on take-off, or flight crew/ATC blunders"; and

- "Air Traffic Management risk".

Departures from runway 34R and SODPROPS both commenced on 19 October 1996.

SODPROPS risk analysis

Section 6.3 of the Legislative Instrument Proposal (LIP) for the Safety Regulation of Airservices Australia specifically detailed the manner in which Airservices was required by CASA to control and manage changes to systems, equipment or procedures to ensure that unacceptable hazards were eliminated by the time the change was completed. The BASI investigation found no evidence that the requirements of this section had been complied with. One form of risk analysis methodology mentioned in the LIP as being acceptable was "assessment of overseas experience..". Claims by Airservices that airspace managers at various overseas airports utilised procedures similar to SODPROPS, were not substantiated. Although the BASI team discovered several examples of international, opposite-direction, parallel runway operations, these were not regarded as sufficiently similar to the Sydney operation to be used as justification in the risk analysis.

The risk analysis provided to the domestic operator, with a matrix of data, suggested that a form of quantitative modelling had been conducted using a narrow set of data. The assumptions for the modelling were not analysed and the model itself was not validated as required in the LIP.

The BASI investigators were supplied with the same matrix of data when Airservices officers were asked to supply full details of the risk analysis associated with the introduction of SODPROPS.

Additionally, there was no record available to the investigation team to indicate that CASA or the Parallel Runway Standards Evaluation Group had conducted any significant analysis of the risks associated with the development and adoption of the SODPROPS standard for Australian use.

Significant Factors

  1. The crew of the A320 dialled an incorrect heading into the FCU, although the pilot in command read the correct heading back to ATC.
  2. The A320 crew followed normal procedure and contacted Departures (S) as soon as practicable after take-off. This frequency change prevented the aerodrome controller correcting the tracking error of the A320 crew.

ASSOCIATED FACTORS

  1. The Civil Aviation Safety Authority adopted the SODPROPS standard without critical analysis of the FAA standard or the risks associated with the application of the standard to Australian operations.
  2. Airservices Australia implemented the standard without fully complying with the requirements of section 6.3 of the LIP.

Analysis

The crew of the A320 set an incorrect heading into the FCU as they were turning onto the runway. They had discussed the need to turn left after take-off and had correctly read back to the aerodrome controller the radar heading for this turn after take-off. Both pilots had followed the company procedures required for setting the departure heading into the FCU, but the cross-check process did not detect the incorrect heading that had been set. It is possible that the training situation in the cockpit, lack of familiarity with the procedure, and the action of setting the heading whilst turning onto the runway had prevented the pilots from recognising that the heading they had set in the FCU was, in fact, the runway heading.

The aerodrome controller was unable to resolve the situation because when he determined that the A320 had not turned left, the A320 crew had already transferred to the Departures (S) frequency. Had the A320 crew remained on the tower frequency until established on the assigned departure heading, the controller would have been able to immediately instruct the crew to turn onto the correct heading.

The SODPROPS procedure was introduced to the Sydney Airport environment with neither the regulator nor the air service provider having adequately analysed the risks associated with the implementation of the standard. CASA did not critically examine how the standard was developed by the FAA and did not determine if any restrictions were applied when the standard was utilised in the USA. Furthermore, CASA did not determine the extent to which this standard was used in other countries where the regulators' experience might have been able to influence the standard's development for use in Australia.

Although Airservices had agreed to comply with the requirements of the LIP until the document was signed into law by the Minister, the evidence indicated that the requirements for risk analysis of new procedures in the LIP were not complied with prior to the introduction of SODPROPS.

Airservices commenced the consultation process with industry less than 4 weeks prior to the planned implementation of the procedure. This period did not give the industry sufficient time to consider the procedure, or to develop and distribute internal procedures that incorporated the new operation. Because industry representatives were provided with details of the risk analysis 2 days before the operation was due to start, there was insufficient time for industry analysis of those details.

Summary

Simultaneous opposite-direction parallel runway operations (SODPROPS) were being used at Kingsford-Smith Airport (KSA) Sydney. An Airbus Industrie A320 aircraft was departing towards the south from runway 16L, and an international Boeing 747 (B747) was tracking towards the north, established on final approach for runway 34L. The A320 aircraft was crewed by two pilots, with the manipulating pilot seated on the right side undergoing training to be a training pilot. Only one of the pilots had previously flown the SODPROPS procedure but during the departure briefing, the pilots discussed the requirement to turn left after take-off.

The SODPROPS procedures were carried out by the aerodrome controllers in accordance with the Sydney District Office local instructions approved by Airservices Australia (Airservices), with the exception that the A320 crew was assigned a radar departure with an initial left turn onto 115 degrees instead of the preferred BOTANY BAY HEADS ONE Visual Departure procedure. The crew mistakenly dialled 155 degrees into the aircraft's flight control unit (FCU) on the glareshield as the aircraft lined up on the runway, but correctly acknowledged to air traffic control (ATC) the assigned heading of 115 degrees.

After take-off, when the crew selected the heading mode on the FCU, they realised that they had set an incorrect heading and maintained runway heading (155 degrees). The aerodrome controller saw that the A320 did not turn left as instructed, but as the crew had already transferred to the departures south (Departures (S)) frequency, he was not able to instruct them to turn left onto the correct heading. When communications were established with Departures (S), that controller directed the crew to turn left to 115 degrees. The A320 crew reported that they had the arriving B747 in sight at all times, but the crew of the B747 did not sight the A320.

The aircraft did not breach the separation standard for the SODPROPS approach.

Safety Action

As a result of the investigation into this occurrence, the Bureau of Air Safety Investigation made the following recommendation to the Civil Aviation Safety Authority in conjunction with the Gliding Federation of Australia on 13 August 1997:

R970092

The Bureau of Air Safety Investigation recommends that the Civil Aviation Safety Authority in conjunction with the Gliding Federation of Australia;

  1. establish a protected circuit area around airfields that have considerable gliding activity;
  2. establish a procedure that all inbound aircraft be required to make an all-stations radio call advising their intention to enter the protected circuit area mentioned above;
  3. apply a speed restriction of 80 kts indicated airspeed to gliders operating in this protected circuit area at all times other than during official competition events (aircraft other than gliders should operate at minimum safe speed within the area); and
  4. investigate the benefit of the application of high-visibility markings for all Australian registered gliders.

Gliding Federation of Australia response

An initial response was received from the Gliding Federation of Australia (GFA) on 12 September 1997, rejecting all but the last recommendation. A further response was received from the GFA on 9 October 1997. The response stated in part:

Summary

  1. The GFA recognizes that the rate of mid-air collisions involving gliders is unacceptably high in the circuit areas of aerodromes and will implement measures to improve discipline in flying the pattern and making better use of the radio.
  2. The GFA is unwilling to accept the imposition of mandatory radio for gliders in an area where it is optional for all other traffic.
  3. Although it is, on the face of it, difficult to argue with the recommendation for a speed limit for gliders, there are considerable numbers of fast homebuilt aircraft such as the Long Eze which have a frontal area not much different from that of a glider and are thus just as difficult to see. In fact, because of their shorter wingspan, they have even less frontal area in some cases. Given that the Tocumwal accident occurred above the circuit area and there are no other accidents on record where high glider speed in the circuit was shown to be a factor, there is no justification for the recommendation.

    In spite of the above comment, GFA will closely examine the feasibility of requiring in future that any "abnormal" circuit entry, be it a high-speed entry or an inadvertent entry from an unusual position, be preceded by an "all stations" call from a radio-equipped glider, warning other traffic of the glider's position and intentions. In the case of a non-radio glider, a high speed circuit entry will not be permitted (except at a NOTAMed contest) and pilots "caught out" by conditions and entering from unusual positions must fly so as to avoid other traffic in accordance with the CARs.
  4. A shift in emphasis is needed in cross-country training, from the euphoria of completing the task to a positive concentration on the complex circuit-joining task ahead and its consequent need for a full lookout scan and any radio calls that may be appropriate. For all joining traffic, whether from cross-countries or not, the concept of a "wake-up call" when about to enter the circuit area must be developed and we are working on that.
  5. A strategy needs to be devised to cope with the increasing complexity of cockpit instrument systems, especially when entering known busy traffic areas.
  6. BASI has identified the phenomenon of "skill fatigue", one of the symptoms of which is fixed vision and a failure to scan the sky. Given that the complex nature of many gliding tasks makes skill fatigue a likely factor in our sport, there will be an education campaign warning of the need to "keep something in reserve" for the complex task of joining a known busy part of the sky after the relatively low-risk enroute task which has just been flown.

    I trust this explains and summarises the GFA position on this matter".

Response classification: CLOSED - PARTIALLY ACCEPTED

GFA/BASI Meeting

Subsequently a meeting between BASI and the Director of Operations of the GFA was held on 13 January 1998. The following is a summary of the outcomes of that meeting:

  1. The proposal for a protected area around aerodromes with significant gliding activity was not supported. Instead it was agreed that the size of the CTAFs at these locations be reduced from a non-standard 15 NM radius to the standard 5 NM radius.
  2. It was agreed that the GFA recommend a circuit entry broadcast become a standard operational procedure for all radio-equipped gliders that, due to variation in conditions or unforeseen circumstances, can not enter or comply with the standard traffic pattern for that location. The GFA publication "Airways and Radio Procedures for Glider Pilots" to be amended accordingly. It was also agreed that a procedure would be developed for non radio-equipped gliders to follow in similar circumstances.
  3. The recommendation for an 80 kt speed restriction to gliders operating in the circuit area was rejected. An alternative course of action to address this issue, as suggested by CASA, was the avoidance of abrupt vertical manoeuvres in the circuit area. It was proposed that BASI discuss with CASA the incorporation of the avoidance of abrupt vertical manoeuvres in the circuit area, into the relevant section of the Aeronautical Information Publication.
  4. The GFA expressed a willingness to participate in any additional study to investigate the benefit of high-visibility markings on gliders. BASI will encourages the GFA and others to continue research on this subject.

Civil Aviation Safety Authority response

A response was received from the Civil Aviation Safety Authority (CASA) on 19 September 1997. This response disagreed with some of the recommendations and instead suggested some alternatives.

Following the GFA/BASI meeting, a copy of the letter to the GFA, summarising the agreements reached at that meeting, was sent to CASA.

The following response was received from CASA on 6 April 1998:

"Thank you for your letter of 3 February 1998 with the results of a meeting between BASI and the GFA at which the BASI report on the Tocumwal and Horsham glider mid air collisions were discussed.

CASA concurs with the recommendations resulting from this meeting and will instigate action to implement the reduction in the size of the Tocumwal and Benalla CTAFs".

Response classification: CLOSED - ACCEPTED

LOCAL SAFETY ACTION

As a result of this occurrence, Sportavia Soaring Centre of Tocumwal, wrote to BASI on 27 August 1997, advising:

"Having read your Air Safety Recommendation on No R970092, we are in full agreeance with the report and also fully agree with the recommendations put forward.

It is our intention to implement immediately the recommendations outlined in the report: They are:

  1. A mandatory 15nm inbound radio transmission by all gliders.
  2. A 3nm inbound transmission by all gliders entering the circuit area.
  3. A radio call on executing the circuit entry.
  4. 80 knots indicated airspeed maximum for all gliders inside the circuit area, except during official competitions.
  5. The circuit is defined as below 2000 AGL and 3nm radius.

We believe these actions will reduce the possibility of a repeat accident of this nature. Trusting that this is to your satisfaction".

Significant Factors

  1. There were no established radio procedures specifically for gliders entering the circuit area within the Tocumwal CTAF.
  2. The pilot of GKT entered the area above the circuit, unannounced at high speed.

Analysis

Flight history of GKT

No evidence was found to indicate where the pilot of GKT had been flying during the approximately 6 hours since the glider had been launched. The manoeuvre he was flying appeared to be a practice 'final glide' which is normally a high-speed arrival at the end of a competition flight. There was no competition in progress that day and the pilot was not engaged on any specific task.

Radio procedures

Both aircraft were equipped with VHF radios and both were selected to the correct frequency, but club staff did not hear any calls from either aircraft. The only requirements in force at the time on the use of radio was a mandatory call to be made when about to enter the Common Traffic Advisory Frequency (CTAF) area. The CTAF at Tocumwal is larger than normal with a radius of 15 NM and, if GKT had remained inside that area, there was no mandatory requirement for the pilot to make a radio call. However, the AIP states that when arriving or departing from an aerodrome, pilots of radio equipped aircraft must monitor the CTAF and use their discretion in making other than the mandatory calls to assist other traffic.

There was a local procedure in force that required the tug pilot to make a 'tug rolling' call just before beginning the take-off. Although in this cast the call was made only a few minutes before the collision, no response was heard from the pilot of GKT.

Summary

The pilot of VH-GKT was of Swiss nationality and he had arrived in Australia from Switzerland 4 days prior to the accident. He had been in Tocumwal for 3 days and he had attended an orientation and procedures briefing at the club on the morning of the first day. He was an experienced glider pilot and had flown two short check flights in a dual-control glider with a senior club instructor. No details of these flights were available, as the instructor who carried out the checks was the pilot in command of VH-GVS involved in the mid-air collision, and was fatally injured.

On the day before the accident, the foreign pilot flew a single-seat glider for a period of nearly 6 hours, after launching at approximately 1200 Eastern Summer Time ( EsuT). He stayed in accommodation at the airfield and attended a social function that evening but did not discuss his flights in detail with the gliding club staff who believed that he had flown in the local general area.

History of the flights

On the day of the accident, the pilot was launched in GKT by aerotow at about 1115. The aircraft was the same high performance single-seat glider that he had flown the previous day. He had not submitted a task declaration and club staff believed he was again intending to operate locally. Nothing was heard from the pilot of GKT throughout the day. The weather at the time was clear, no cloud below 10,000 ft and wind about 6-10 kts from the north with visibility greater than 15 km.

At about 1725 ESuT, GVS, a tandem two-seat glider, was launched by aerotow from runway 36. The front seat was occupied by an inexperienced pilot receiving refresher training from the club's senior instructor, located in the rear seat. The aircraft released from the tug at about 2,300 ft AGL and was seen to begin normal slow-speed manoeuvring in the upwind position, north-west of the field. It had been released for only about 2 or 3 minutes before the collision with GKT.

Sequence of events

GKT was observed to approach the circuit at high speed from the north-west by an eyewitness located at the launch area near the end of the runway. At about 2 km from the airfield, the glider was observed to pull up rapidly and impact GVS.

The nose of GKT initially contacted the leading edge of the left wing of GVS from the left front quarter at an angle of about 55-60 degrees while banked about 15 degrees right. GVS was in slightly descending flight and probably banked slightly left. The nose of GKT then penetrated the centre section of GVS just behind the rear cockpit.

The collision destroyed the cockpit of GKT, severely damaged the left wing and wing attachment points at the centre section, allowing the broken left wing and complete right wing to detach from the aircraft. The T-tail was broken off at the end of the tail-boom and the fuselage continued through the centre section of the other glider. The fuselage section of GKT continued in the direction of flight until it impacted the ground several hundred metres from the collision point. The pilot received fatal injuries.

The outer half of the damaged left wing of GVS detached from the airframe. The relatively undamaged right wing (still loosely attached to the airframe) rotated around the destroyed centre section, until it was upside down on the left side of the fuselage, as the aircraft descended in a flat spin.

The initial impact of the left wing of GKT destroyed the canopy of GVS, and the damage to the centre section and seat harness attachment points caused the rear seat occupant to fall from the aircraft. Both occupants of GVS received fatal injuries, either at the point of collision or the subsequent ground impact.

Significant Factors

  1. The aircraft was flown before necessary certification processes were completed.
  2. The aircraft performed a barrel roll or similar manoeuvre for reasons undetermined, and the engine stopped during the manoeuvre.
  3. The engine stoppage was most probably due to fuel starvation.
  4. The pilot lost control of the aircraft and was unable to regain control before the aircraft struck the ground.

Analysis

The investigation established that the aircraft performed a barrel roll or similar manoeuvre to the right, followed immediately by a series of flick rolls or a spin to the left. (A barrel roll is a manoeuvre where the nose of the aircraft is made to travel around a spiral path which is some distance from the axis of the roll. A flick roll is a manoeuvre where the aircraft is induced into a stall at a higher than normal speed and the aircraft rotates or rolls rapidly about its longitudinal axis. A spin is characterised by the same rotational movement but the axis of a spin is usually vertical.) The investigation could not establish any reason for the manoeuvre. During the course of the roll, the engine noise was heard to cease, and this was most probably due to fuel starvation. The investigation established that the centre of gravity may have been near the aft limit and this would have accentuated the uncontrolled manoeuvre and reduced the chances of recovery by the pilot. During the recovery from the rolling manoeuvre, the aircraft then stalled and rolled rapidly left two or three times before ground impact.

The engine was estimated to have been running for approximately 50 minutes before the accident. As a result, the fuel quantity remaining may have been insufficient to allow continued fuel supply to the engine when the aircraft was banked steeply, and may have caused the engine to cease operating due to fuel starvation.

Summary

The homebuilt aircraft had been completed over a period of about 22 years and was in flying condition. The aircraft, known as the Smyth Model S Sidewinder, was designed in the USA in 1958. The designer was aiming to produce a sporting monoplane that was reasonably easy to build, easy to fly, stressed to 9g for aerobatics, and economical in operation. The first flight of this aircraft type was made on 21 February 1969 and it received the Outstanding Design Award at the 17th Experimental Aircraft Association Fly-in that year. Plans became available to amateur constructors and in 1973 the plans for the accident aircraft were purchased by the owner.

By 1978, the fuselage construction was well advanced and the initial inspection was carried out. The project proceeded slowly and in 1985 the owner moved from NSW to live in Qld. The aircraft was nearing completion in 1994 when the owner made an application to the then Civil Aviation Authority (CAA) to reserve the registration VH-LKV. The aircraft was a first of type in Australia, and the necessary certification processes were incomplete. At the time of the accident, the aircraft was unregistered and did not have a certificate of airworthiness or a permit to fly. However, the pilot on the accident flight had flown the aircraft some weeks earlier on its first flight.

It had not been the intention of the owner to fly the aircraft on the day of the accident. The pilot arrived at the aerodrome and found the owner and his friend working on the aircraft. After some discussion, the pilot suggested to the owner that they should take the aircraft for a flight. The owner initially declined the offer but the pilot persuaded him to accede to the suggestion. Subsequently, the pilot added 20 L of fuel to the main fuel tank, which had contained about 6 L of residual fuel. The pilot then assisted the owner and his friend to replace panels and cowling and to prepare the aircraft for flight.

The weather was fine with a light south-easterly wind. Witnesses observed the aircraft taking off from runway 06. After take-off, the aircraft initially flew low down the runway with a tail-down attitude, and then began a shallow climb. A flight of about 30 minutes was conducted, during which the pilot demonstrated some of the handling characteristics to the owner. The pilot also carried out circuits and landings during this period. The aircraft was then landed and taxied back to the hangar. While the engine was running and the owner was getting out of the aircraft, the pilot motioned to the owner's friend to come over to the aircraft. The friend indicated to another person he was with at the time, that he did not wish to go flying as he would be late getting home. However, he boarded the aircraft and the pilot taxied out for another take-off.

The aircraft became airborne, again from runway 06, and headed north-east for about 2 km before turning left and heading back towards the aerodrome. When the aircraft was over the aerodrome at about 1,000 ft, witnesses saw the aircraft descend in a shallow dive and then perform what appeared to be a steeply banked manoeuvre or barrel roll to the right. One witness said he remembered seeing the belly of the aircraft faced towards him. Another witness said the aircraft rolled completely over in what appeared to be a controlled manoeuvre. During this manoeuvre, a third witness heard the engine noise increase and then completely cease. The aircraft recovered to a level attitude but immediately flick-rolled to the left and adopted a steep nose-down attitude. The aircraft continued to flick-roll or spin and struck the ground. The aircraft was descending almost vertically at impact with a 30-degree nose-down attitude. There was no fire and the impact was not survivable.

Aircraft particulars

This was the first aircraft of its type to be constructed in Australia. Another builder in WA had commenced construction of a Sidewinder at about the same time, but the project was not completed. The aircraft was powered by a Lycoming Model 0-290-D2B engine which had a take-off power rating of 140 h.p. at 2800 r.p.m. The aircraft was designed with a fixed tricycle landing gear but the subject aircraft had been fitted with retractable gear. The gear was not retracted on the accident flight because the alternate gear extension system was not operative. The main fuel tank had a capacity of 65 L. The two wing tanks each had a capacity of 49 L, and were empty on the accident flight. The fuel consumption quoted by the engine specifications was 6.5 US gal or 24.6 L/h for economical cruise. Fuel consumption for the pre-accident flights could not be determined but would have been significantly higher than the economical cruise consumption because of the nature of the flights.

The aircraft was fitted with fully functioning dual controls and side-by-side seating for two persons. The constructor's manual quoted a stalling speed of 48 kts and a maximum speed (Vne) of 174 kts. The flight characteristics of this aircraft were unknown as a flight test schedule had not been carried out. The empty weight of the aircraft was approximately 477.5 kg but a final weighing of the aircraft had not been carried out as was required for certification of type. The aircraft had been test flown in December 1996 by the accident pilot. After that flight, the pilot had expressed his dissatisfaction with the aircraft's stalling characteristics, and said that he would not fly it again. It was discovered that the aircraft had 26 L of fuel in the left-wing tank and no fuel in the right tank. This may have affected the stalling characteristics.

Damage to aircraft

The aircraft impacted the ground whilst rotating to the right with a nose-down attitude of approximately 30 degrees. The cockpit area was destroyed by the impact. The engine was embedded in the ground to a depth of about 0.5 m. One propeller blade was sheared off and fragmented by impact. The fractured surface indicated no powered rotational movement at the time of impact. The remaining propeller blade was intact and undamaged. The cockpit structure and floor had been compressed forward against the rear of the engine. The force of impact against the rear of the engine had fractured the engine gear housing. The throttle was found in the fully open position, the mixture fully rich and carburettor heat control in the cold position. However, the position of the cockpit controls before impact could not be positively determined due to the extent of damage. The main fuselage fuel tank had disintegrated and there was no evidence of fuel at the accident site immediately after the accident.

Wreckage examination

Examination of the airframe did not reveal any failure or defect which might have contributed to the accident. The engine exhaust pipe was metallurgically tested and was at less than operating temperature at impact. The engine was bulk stripped and no defects or failures were discovered other than those caused by impact damage. The retractable landing gear was in the extended position at impact. During the investigation the possibility of propeller or spinner failure was considered, but there was no evidence to support this hypothesis. The possibility of a bird strike was also considered, but again there was no evidence found during the wreckage examination to support this theory.

Weight and balance

The aircraft had been weighed on 10 January 1994 to determine the empty weight and centre of gravity. A final weighing was required after fitting of the radio and other equipment but this had not been carried out. The actual weight and balance at the time of the accident could not be determined. However, based on the initial weight and balance determination, the aircraft was within the weight and balance envelope and the centre of gravity near the prescribed aft limit. The summary showed that with two persons on board and no fuel, the centre of gravity was 0.55 inches forward of the aft limit.

Personnel information

The pilot was the holder of a senior commercial pilot licence (aeroplane) and was qualified and endorsed on the aircraft category. He had flown the aircraft on one other occasion some three weeks before the accident, but otherwise had no experience on the particular aircraft type. He was, however, widely experienced with over 38 years as a flying instructor, airline pilot and general aviation pilot. He had previously test flown a home-built aircraft for the passenger on the accident flight. The passenger held a student pilot licence and had accumulated about 267 hours aeronautical experience.

Medical information

The pilot was medically fit and qualified to perform the flight. He had a current class one medical certification status. There was no evidence found to indicate that there were any physiological or medical factors which may have contributed to the accident. The passenger was medically fit and held a valid medical certificate for his licence category.

Meteorological conditions

Witnesses reported conditions at the time of the accident as fine with a light easterly breeze. There was an insignificant amount of high-level cloud and the temperature was 24 degrees C.

Communications

The aircraft was fitted with a VHF radio. The Caboolture aerodrome is outside controlled airspace but within the Caloundra/Redcliffe Common Traffic Advisory Frequency area. The frequency is used for inter-aircraft and advisory communication and is not recorded. There was no other known flying activity in the vicinity of Caboolture aerodrome at the time of the accident, and it is not known if there were any transmissions made from the aircraft immediately before the accident.

Aerodrome information

The Caboolture aerodrome is unlicensed. The grass runways are 06/24 and 12/30, and are 900 m and 1,350 m in length respectively. The aerodrome is 40 ft above sea level. The aircraft impacted the aerodrome on the southern side the runway 06 flight strip near the north-eastern end of the runway.

Death of the Master on board Arktis Grace

Final report

Summary

The small general cargo/container vessel, Arktis Grace arrived in the port of Townsville on 16 August 1996 after a voyage from Papua New Guinea. The voyage had been at reduced speed due to machinery problems. It had no cargo to discharge and remained in Townsville to complete repairs. On 12 October 1996 the ship was still lying at no. 6 wharf in Townsville, awaiting spares for the main gearbox.

The 53-year-old Master was due to pay off from the ship on 15 October and to return to his home in Denmark for leave. On the evening of Saturday 12 October, he and his friend of long standing, the Chief Engineer, went ashore for a farewell dinner. They started the evening with drinks at an hotel near the docks, then went into town for dinner and finally to another hotel before returning on board Arktis Grace at about 2145 that evening.

The Chief Engineer boarded the ship first, while the Master paid the taxi driver. Shortly afterwards, the crew heard a loud crash and felt the ship shudder. The gangway was found tipped on its side and the Master was seen floating face down in the water between the shipís side and the wharf.

The Chief Engineer and a crew member jumped into the water in an attempt to save him. The Master was a big man weighing about 140 kg and, despite their efforts, he was later found to have drowned.

The incident was investigated by the Marine Incident Investigation Unit under the provisions of the Navigation (Marine Casualty) Regulations.

Conclusions

These conclusions identify the different factors which contributed to the circumstances and causes of the incident and should not be read as apportioning blame or liability to any particular organisation or individual. It is concluded that:

  1. The Master of Arktis Grace died by drowning, after falling from the vesselís gangway into the gap between the shipís side and the wharf.
  2. The hand-ropes of the gangway were sufficiently slack to allow the Masterís centre of gravity to move outside the edge of the narrow gangway and for his weight to tip it over.
  3. The hand-ropes had not been tended and tensioned regularly by the deck watch as the vessel rose and fell with the tides.
  4. The Chief Engineer and the ordinary seaman in the water did all they could to try to save the Master.
  5. There was an excessive delay before an ambulance was called, explained in part by the fact that none of those on board knew the emergency number to call, and the number was not displayed in a prominent position adjacent to the telephone.
  6. The Inspector considers that the consumption of alcohol in the hours preceding his death, which led to an apparent blood alcohol level of .291%, was a significant factor in the impairment of the Masterís sense of balance on the gangway.
  7. Had a safety net been rigged underneath the gangway, as required by the Port of Townsville By-laws during the weeks immediately preceding the incident, it may have prevented the Master from falling into the water.

Collision between FV Galaxy and Adam Tenggiri

Final report

Summary

Early in the morning of 6 September 1996, the Malaysian cargo ship Alam Tenggiri was about 65 miles east-by-south of the Queensland port of Mackay, en route from Bing Bong, in the Gulf of Carpentaria, to Newcastle, New South Wales. The weather was fine, the visibility clear and the sea calm.

At about 0120 Eastern Standard Time, the officer on watch saw the light of a vessel ahead on the port bow. Alam Tenggiri was making good a speed of about 12.8 knots, with High Peak Island about 20 miles on the starboard bow. After watching the other vessel, he deduced that the vessel was on a parallel or nearly parallel course and that his ship was the overtaking ship and had a duty to keep clear. He started an ARPA plot and determined the closest point of approach of the other vessel.

The fishing vessel Galaxy was relocating from fishing grounds off Mackay to grounds further south, to the west of the Capricorn Group. The Skipper handed over the watch to the vessel's Cook, who maintained a lookout and a check that the vessel followed the course displayed on the vessel's plotter, which was connected to the GPS. The Cook saw no other vessels.

At about 0240, collision seemed imminent and Alam Tenggiri's rudder was put hard to starboard. As the starboard trawl boom of the fishing vessel came into contact with the port side railing of Alam Tenggiri the cargo ship's rudder was put hard to port. The smaller fishing vessel passed down the port side of the cargo ship.

The Alam Tenggiri started to slow its engine in readiness for turning about to render assistance. After about 20 minutes VHF radio contact was established and information was exchanged. The fishing vessel reported that it had sustained damage to its boom but did not require assistance.

The collision occurred in approximate position 2150.5' South 15048' East. Alam Tenggiri continued on its voyage to Newcastle. Galaxy abandoned the voyage to the new fishing ground and set a course to return to its home port of Caloundra.

Conclusions

These conclusions identify the different factors contributing to the collision between Alam Tenggiri and Galaxy and should not be read as apportioning liability or blame to any particular ship or individual.

It is considered that the fishing vessel Galaxy was on a steady course of about 150 and the following factors contributed to the collision:

  • The Second Mate on Alam Tenggiri, having seen the light of the vessel being overtaken, did not keep a proper lookout in that he did not make a full and effective appraisal of the situation and of the risk of collision.
  • The Second Mate placed too great a reliance on ARPA without a full appreciation of its possible inaccuracies.
  • A prolonged period of overtaking involving no immediate risk of collision reduced awareness of the potential danger of eventual collision.
  • Given the extent of open water available, Alam Tenggiri did not give sufficient sea room to the vessel being overtaken.
  • The person on lookout on board Galaxy did not keep a proper lookout and did not detect the overtaking vessel by sight or radar.
  • Although the manning of Galaxy met the requirements of the Australian Transport Advisory Council's Uniform Shipping Law Code, the person on lookout on board Galaxy was not qualified, had no training in the use of radar and did not have the knowledge to maintain a watch.

Fatality aboard the Matilda Bay

Final report

Summary

On the morning of 17 August 1996, the 25,093 gross tonne Hong Kong flag container ship Matilda Bay was crossing the Great Australian Bight, on passage from Melbourne to Fremantle in Western Australia. At 0800, the ship was in the position 3722'S, 13150'E, approximately 240 nautical miles WSW of Kangaroo Island. At about 0800, the Second Engineer reported to the bridge that sunlight could be seen coming into the forecastle through the small 'booby' hatch on the forecastle head.

The Chief Officer, after leaving the bridge, made his way forward along the main deck to investigate, taking the Bosun and two Able Seamen (ABs) with him. He had not advised the Third Mate, now on watch on the bridge, nor anybody else, that he was going to the forecastle. He had no radio with him. The four men went onto the forecastle where they found the lid of the booby hatch had been torn off. Attempts to replace it proved fruitless, as it was distorted, so the Chief Officer sent the Bosun to get materials with which to improvise a hatch cover.

Shortly after this, a green sea swept the forecastle, carrying one AB right over the top of the windlass and the other AB against the front of it. The Chief Officer was swept underneath the windlass. The AB who had been swept over the windlass, stunned, called out to the other two who did not reply. He, thinking they had been washed overboard, made his way off the forecastle and told the Bosun what had happened. The Bosun sent the duty AB to the bridge to inform the Officer of the Watch of a man overboard situation.

The Officer of the Watch commenced a Williamson turn and sounded the 'man overboard' alarm. Shortly before 0900, while the vessel had started searching for the men believed overboard, the other AB, recovering on the forecastle, found the Chief Officer under the windlass. Making his way aft he told the Bosun that the Chief Officer was still on the forecastle. The Chief Officer was stretchered aft to the ship's hospital. He had suffered severe head and chest injuries and a broken leg. It was found later that the two ABs had not sustained serious injury. At 0945, the MRCC in Canberra was contacted asking for medical advice and for the nearest port for a medevac of all three.

Those tending the Chief Officer were unable to stem the profuse bleeding from his head injuries. In spite of prolonged CPR and the administering of oxygen, all vital signs had disappeared by 1330 and it was concluded that he had died at some time before that. The ship resumed its course to Fremantle where it arrived on the evening of 19 August.

The incident was investigated by the Marine Incident Investigation Unit on behalf of the Hong Kong Marine Department.

Conclusions

These conclusions identify the different factors which contributed to the circumstances and causes of the incident and should not be read as apportioning blame or liability to any particular organisation or individual.

  1. The Chief Officer died as a result of multiple injuries received when he was swept underneath the windlass by an unexpectedly high sea coming over the forecastle.
  2. The ship, at the time of the incident, having slowed down on the previous evening, was proceeding at an appropriate speed for the prevailing weather conditions.
  3. The forecastle had not been properly secured for sea when the ship sailed from Melbourne, on 15 August, and this resulted in the cover of the booby hatch being torn off by the heavy weather encountered crossing the Bight.
  4. The fact that the Chief Officer had not informed the bridge or the Master of his intention to proceed forward meant that no assessment was made of the risk of working on the forecastle, repairing the hatch cover, in the prevailing sea conditions.
  5. The fact that the Officer of the Watch was unaware that men were to work on the forecastle resulted in the course of the ship being maintained into the heavy weather when it could have been changed to run with the weather for the duration of the repairs, thereby making it safer to work forward.
  6. Neither the Chief Officer, nor anyone else in the group on the forecastle, had a radio with which to maintain contact with the bridge. This, combined with language difficulties and shock, contributed to the confusion which prevailed for a while after the incident and to the delay before the Chief Officer was found underneath the windlass.
  7. The Master and officers of Matilda Bay did everything possible under the circumstances, and with the medical equipment available on board, to save the life of the Chief Officer.

Grounding of the Niaga 46

Final report

Summary

At approximately 1600 hours on 8 August 1996, the Indonesian cargo vessel Niaga 46, arrived at Christmas Island, about 4.5 miles to the Northwest of Flying Fish Cove. The ship was due to berth at 0600 the following morning to load 7,600 tonnes of rock phosphate.

Christmas Island is "steep to" and ships do not anchor but drift while waiting to berth. Niaga 46 hove to in position with North West Point bearing 270 x 2.5 miles, to drift overnight. Sea watches were maintained and the engine was on ten minutes notice of readiness. The wind was blowing from a southerly direction at 17 knots and the anticipated current was west going at about 2 knots.

By 2132, the vessel had drifted west towards North West Point and the Third Mate decided to reposition the ship. At 2323, the vessel was repositioned about 2.5 miles due east of North West Point.

At midnight, the Second Mate had not arrived on the bridge, so the Third Mate handed over the watch to the 12-4 apprentice and left the bridge at about 0005. The Second Mate arrived on the bridge at about 0010 and switched on the starboard radar to check the ship's position. The radar showed Niaga 46 as being close to the land east of North West Point. He rang the duty engineer and requested use of the engine. The engine was ready at 0039, however, before the Second Mate could manoeuvre clear of the land the ship grounded at 0047 about 6 cables east of North West Point.

At 0605, contact was made with the Harbour Master, Christmas Island, and he boarded the ship a little after 0700 on 9 August. The Harbour Master took charge of the refloating operation and, after a number of unsuccessful attempts, the vessel was refloated at 2300 on 9 August.

The vessel suffered extensive damage and was taken in tow to a repair port in Indonesia.

Conclusions

These conclusions identify the different factors contributing to grounding of Niaga 46 and should not be read as apportioning liability or blame to any particular individual or organisation.

It is probable that when the Third Mate left the bridge, Niaga 46 was still making way through the water as a result of the prolonged use of the engine at full harbour speed while repositioning the ship between 2132 and 2323. This, combined with the following factors, contributed to the grounding:

  1. The Third Mate absenting himself from the bridge before the Second Mate arrived to take up his watch.
  2. The hand over of the watch at midnight to the apprentice, was inappropriate, not thorough and did not reflect the true status of the ship in relation to the status of the navigation equipment and the proximity of the land.
  3. A complete lack of acceptable watchkeeping standards and an absence of basic seamanship practices.
  4. A lack of any realistic assessment by the Master or deck officers of the risks involved while drifting off Christmas Island, together with the lack of planning and determination of sensible safety margins.
  5. A lack of clear direction and control over the conduct of the watchkeeping officers by the Company and Master.
  6. Poor general management of the ship, and its operation.

Fire aboard the bulk carrier Docebay

Final report

Summary

On the morning of 13 May 1996, the 152,308-tonne dwt. Liberian flag bulk carrier Docebay was on ballast passage from Japan to Dalrymple Bay in Queensland. At 0400, the ship was at the position 1347.7' S, 153 56.8' E, approximately 500 nautical miles north-east of Townsville.

Shortly before 0400, the Second Engineer had left his cabin for his 0400-0800 watch in the engine room. At about 0405, the First Engineer, in the cabin adjacent to that of the Second Engineer, heard the sound of a fire and felt heat through their common bulkhead. He telephoned the engine room, and the Second Engineer returned to his cabin, where, upon unlocking and opening the door, he was met by a blast of heat and black smoke. The ship's fire detection system went into alarm. The fire very quickly gained a hold in the cabin as the ship's crew started to tackle the fire from the Chief Engineer's cabin, at the forward end of the alleyway, and from the external door at the aft end of the alleyway. The ventilation was shut down and boundary cooling was applied to the decks above and below the Second Engineer's cabin.

At 0432 the Master broadcast a Mayday message which was received and acknowledged by the Maritime Rescue Co-ordination Centre in Canberra.

After 1 hours the fire was extinguished, and the Mayday was cancelled. The fire had gutted the Second Engineer's cabin and caused extensive smoke damage to other areas on the same deck. Nobody had been injured during the incident.

The vessel anchored at Hay Point on 14 May before loading its cargo of 130,000 tonnes of coal for Praia Mole in Brazil.

Before the ship arrived at Hay Point, the cabin was completely cleaned out. This action, unfortunately, removed any evidence which would have assisted in determining the cause and origin of the fire. Nevertheless, the investigation revealed that in other cabins on the vessel there were electrical extensions, made up by crew members, to provide power from the scarce power points to televisions, VCRs and sound systems situated some distance from them.

Although the lack of available evidence prevented any conclusion being reached on the cause of the fire, an extension lead used in the Second Engineer's cabin, the construction of which would not meet Australian Standards, was suspected.

The incident was investigated by the Marine Incident Investigation Unit under the provisions of the Navigation (Marine Casualty) Regulations.

Conclusions

These conclusions identify the different factors which contributed to the circumstances and causes of the incident and should not be read as apportioning blame or liability to any particular organisation or individual.

The removal of the contents of the cabin, before the investigation started, prevented any definite conclusion being reached regarding either the point of origin or the cause of the fire.

With the lack of available evidence to indicate otherwise, the timing of the start of the fire and the Second Engineer's arising in the morning and leaving his cabin must be regarded as purely coincidental.

The fire took hold quickly and for this to have happened there must have been a supply of combustible materials near the source of the fire.

It is concluded that:

  1. The port after corner of the Second Engineer's cabin appears to have had the most significant concentration of combustible materials together with the television, VCR, and sound system all connected to a power board on an extension lead at this point. On balance of probability, it is likely that the fire started in this area.
  2. The extension lead used would not meet Australian Standards, being unearthed, having below minimum size conductors, having no sheath and the power board being poorly made of flammable, non-impact-resistant plastic. In addition, the power points in the vessel, of American two-pin type, are not switched and therefore appliances cannot be totally isolated from the supply without withdrawing the plugs. This left the extension and power board live at all times.
  3. Although it cannot be stated conclusively, the most likely source of ignition would have been either a fault in the television set while in the 'stand by' condition or a short circuit in the power board of the extension lead.
  4. There was no policy in place on the ship for checking temporary wiring in cabins, installed by members of the crew, to ensure that it was electrically safe. It is understood that, since the fire, this is being addressed.
  5. On the evidence available it is unlikely that arson was the cause of the fire.
  6. The response of the ship's crew to the fire was quick and, on the whole, effective. The fire was well contained by the fire-fighting operations although it would have been better contained had the cabin door been kept closed at the beginning of the incident, until fire hoses had been rigged in place and a water curtain was available.

Grounding of the Panamanian flag Peacock

Final report

Summary

The Panamanian flag refrigerated cargo vessel Peacock, on a ballast passage from Singapore to New Plymouth, New Zealand, embarked a licensed pilot off Goods Island at 1630 AEST on 17 July 1996 for the passage through the Torres Strait and the Inner Two Way Route of the Great Barrier Reef.

At about 0155 on 18 July 1996, the vessel grounded on Piper Reef at full speed, in a position 100 metres eastward of the light beacon. Initial attempts to refloat the vessel by going astern on the engine were unsuccessful.

Peacock remained stranded on Piper Reef until the late afternoon of 26 July 1996, when salvors successfully refloated the vessel after having transferred some of the fuel oil bunkers to a barge.

The vessel's hull was not breached, and no pollution occurred. However, machinery tests showed that only one steering motor was fully functional, therefore Peacock was towed to Cairns for necessary repairs.

Conclusions

These conclusions identify the different factors contributing to the incident and should not be read as apportioning blame or liability to any particular organisation or individual.

Peacock grounded on Piper Reef as a result of the vessel's course not being altered, from 175 to 149, as it approached from the north with the reef right ahead.

The following factors are considered to have contributed to the grounding:

  1. The Pilot's loss of situational awareness, the balance of probability being that he fell asleep.
  2. The Pilot's sitting with his chin cupped in his left hand, making him more susceptible to falling sleep.
  3. The warm, stuffiness of the wheelhouse atmosphere, in association with the sleep-inducing factors of time of day and background environmental noises.
  4. Chronic fatigue as a result of the Pilot's recent work schedule, particularly the high proportion of nights of disrupted sleep.
  5. The lack of a strategy on the part of the Pilot to counter the effects of foreseeable fatigue during periods of reduced activity.
  6. The lack of proper bridge management and lack of interaction between the Pilot and the Watch Officer.
  7. The lack of proper monitoring of the vessel's progress by the Watch Officer.
  8. The attitude of the Watch Officer in assuming the Pilot was solely responsible for the navigation and his prolonged absence from the wheelhouse.
  9. The absence of a formal control framework, to monitor a coastal pilot's nights of disrupted sleep, to prevent the development of chronic fatigue.

Fall from aloft aboard the STS Leeuwin

Final report

Summary

On 12 June 1996, the barquentine rigged STS Leeuwin was cruising in the Timor Sea. On board, in addition to the permanent and volunteer crew, were 31 trainees, mainly young unemployed persons, drawn from all over the Northern Territory and sponsored by the Commonwealth Employment Service.

Shortly after 0830, a team of three trainees, led by their Watch Leader, climbed aloft on the mainmast, to release the gaskets securing the main gaff topsail, so the sail could be set. The second of the three trainees, a woman in her late twenties, fell as she negotiated the futtock shrouds. Although she had clipped on her safety line, the free end of her safety belt slipped through the buckle, and she fell 18 m to the deck.

Fortunately, the fall was partially broken by the nock sail sheet. Even so, the trainee suffered severe multiple fractures to her knees and to her thighs, also a collapsed lung. A helicopter medivac was arranged to transfer her to the Royal Darwin Hospital, where she remained in intensive care for 16 days.

Conclusions

These conclusions identify the factors contributing to the incident and should not be taken as apportioning either blame or liability.

The trainee fell from the futtock shrouds because, although very frightened, she intentionally let go her hand hold in the belief she would be all right.

The main contributing factors to the trainee's fall to the deck are considered to be:

  • The trainee had not fastened her safety belt properly, so that it came undone instead of preventing her from falling further.
  • The absence of a safety check system, which meant that the trainee was able to climb aloft with an improperly fastened safety belt.
  • The onboard philosophy and procedures that removed the safety barrier of safety belt checks before trainees ventured aloft.

Other factors that are considered to have contributed to the accident are:

  • The onboard procedures that allowed a trainee to climb aloft for the first time on the mainmast.
