The ATSB investigation into the fatal Aero Commander accident on 19 February 2004, 58 km NNW of Hobart is focusing on the reason for an overload failure of the wings in flight. The ATSB interim factual Report finds that the wreckage pattern was consistent with the aircraft having sustained an in-flight structural failure of both wings and the tailplane. The outboard left and right wing sections had separated from the aircraft at similar positions along the respective wings and in a downward direction. However, there…

The ATSB final investigation report into the crash that killed the two occupants of a Robinson R22 helicopter at Yakka Munga Station in Western Australia, has found that a drive shaft to the main rotor blades failed. Examination of the shaft revealed that it had failed as a result of a fatigue crack that initiated at a bolt hole in the shaft. Inappropriate procedures, including use of an unapproved sealant, were used when the shaft was last assembled. During the investigation, the ATSB issued an urgent safety recommendation to the Civil Aviation Safety…

The ATSB's final investigation report into an airspace incident on 7 April involving a Boeing 737 and a Lancair aircraft has found that while it was an 'airprox' it was not a 'serious incident' because of timely action by the air traffic controller and both crews. The Boeing 737, operating under the instrument flight rules (IFR), was en route from Townsville and descending for a landing at Brisbane. A Neico Lancair IV-P aircraft, operating under the visual flight rules (VFR), was en route from Maroochydore to St George, on climb to flight level (FL) 165.…

An ATSB report has found that a recent airspace incident was both an 'airprox' and a 'serious incident' and that after taking evasive action, a Cirrus SR20 and a Cessna 172 aircraft passed about 200 metres horizontally and 50 ft vertically from each other. The Cirrus, operating under the instrument flight rules (IFR), was approaching the Cowes VHF omnidirectional radio range (VOR) navigation aid for instrument flight practice in visual meteorological conditions. A Cessna 172 aircraft, operating under the visual flight rules (VFR), was also conducting…

The Australian Transport Safety Bureau has dispatched a team of two investigators to determine the circumstances surrounding the fatal aviation accident near St George, 19 October 2004. The factual circumstances to hand are that it was a private flight from Bundaberg to St. George, Queensland. During the flight, the pilot reported feeling unwell and disoriented. Another aircraft in the area was diverted to formate on the aircraft. The pilot was reportedly lapsing in and out of consciousness. The aircraft was followed…

The Australian Transport Safety Bureau (ATSB) has found that fatigue cracking in the blade slots of a high-pressure turbine disk led directly to the uncontained failure of the left engine of a Boeing 767 aircraft that occurred near Brisbane on 8 December 2002. The aircraft was operating a scheduled passenger service to Auckland, New Zealand and was forced to return to Brisbane airport after the failure. Damage to a wing leading-edge flap from engine debris and the weight of the fuel being carried for the trans-Tasman flight led the flight crew to perform a prepared emergency landing, during…

The Australian Transport Safety Bureau (ATSB) has advised that the door that fell from a Raytheon Beechcraft King Air B300 aircraft on Tuesday 7 September 2004 has been located. The ATSB would like to thank media outlets for their cooperation in publicising our request for assistance in finding the cabin door. The door was located to the south-west of Theodore, Central Queensland. With the assistance of the Queensland Police Service the door will be delivered to the ATSB's laboratories in Canberra for examination. The ATSB will now be in a much better position to determine why the door fell…

Given the heightened interest, the ATSB has released an interim REPORT on progress with its investigation into the tragic Benalla fatal accident, emphasising its complexity due to destruction of the aircraft and the need to carefully address all the safety issues. The ATSB Preliminary REPORT into this six-fatality accident in a Piper Cheyenne was released on…

Failure to keep a proper lookout by either vessel has been identified as the immediate cause of the ninth collision in five years between a fishing vessel and a ship off the Australian coast. In the early hours of 21 August 2003, the fishing vessel Jenabar collided with the bulk carrier Lancelot off Diamond Head on the New South Wales coast. The report on the collision by the Australian Transport Safety Bureau (ATSB) also identifies that over-reliance on board Lancelot on information from the automatic radar plotting aid contributed to the collision. On…
