This publication represents the last in a series of annual reviews, dating back to 1999-2000. Over the last ten years, the Bureau has built a reputation as a world class investigative organisation. This has been chronicled through the ten annual reviews which the ATSB has released. From 1 July 2009, the ATSB has taken on new annual reporting responsibilities which will result in the publication of a very different document. This change is entirely appropriate given the ATSB's status as a newly established statutory agency. However, consistent with our new mandate, I know the Commission will…

Although several studies have reported the common threats and errors identified in line operations safety audits (LOSAs) of high capacity regular public transport (RPT) operations (Klinect, Wilhelm & Helmreich, 1999; Veilette, 2005; Thomas, 2004), there is little information on the types of threats and errors faced by pilots in other parts of the aviation industry. This report catalogues the most common threats to operations, and errors made by pilots, in aerial work and low capacity air transport operations, as perceived by flight instructors, check-and-training pilots, chief pilots and…

On the early evening of 31 January 2001 at Melbourne International Airport, Boeing 777-300 A6-EMM aborted its take-off run at low speed as a result of a failure within the left (No.1) engine. Although the failure was associated with a large compressor surge within the engine, no subsequent fire developed and the aircraft was able to safely return to the terminal building on its remaining serviceable engine. Failure of the RB211 Trent 892 engine as fitted to the aircraft was a result of the release of a single blade from the low-pressure compressor (fan) rotor disk. The blade release caused…

Introduction This publication is the first in a pilot education series by the Australian Transport Safety Bureau (ATSB) on avoidable accidents. In this report, we will focus on accidents involving unnecessary and unauthorised low flying; that is, flying lower than 1,000 ft (for a populous area) or 500 ft (for any other area) above ground level without approval from the Civil Aviation Safety Authority (CASA). Between 1999 and 2008, there were 147 fatal accidents reported to the ATSB involving aerial work, flying training, private, business, sport and…

This information paper reviews the Bureau's policy on testing for drugs and alcohol, attempts to assess the prevalence of drugs and alcohol in aviation accidents and incidents, and discusses the adequacy of the present policy. The policies of Canada, the United Kingdom, and the United States are also outlined.

This report was commissioned by the Bureau of Air Safety Investigation (BASI) to investigate the system of Notices to Airmen (NOTAM) following statements from some airline flight crews that current NOTAM presentation is not optimised to meet their needs. Pilots had stated that: Some NOTAM are not clearly written, The NOTAM format can be difficult to decipher, There is too much irrelevant information provided.

MTAF procedures were introduced in Australia with the AMATS changes of 12 December 1991. The MTAF procedure applies at specified aerodromes. It depends on pilots making mandatory radio calls, hearing calls from other aircraft, assessing this traffic information for potential conflict, and responding appropriately with radio communication and avoiding action if necessary. The MTAF procedure is designed to alert aircraft to all other air traffic in a designated area surrounding a particular aerodrome. The procedure mandates certain radio broadcasts and responses in these areas, and the pilots…

The Bureau of Air Safety Investigation recently conducted research into the rates of G onset and G levels experienced by a light aircraft pilot during normal aerobatics. The objective was to relate data obtained from the research to other data available from military authorities, in order to evaluate the possibility or otherwise of a light aircraft pilot sustaining G-induced loss of consciousness (G-LOC) during aerobatics.

The status of commercial passenger operations in turbine powered single engine aeroplanes is presently under review by the civil aviation regulatory authorities of several nations. In this information paper BASI offers no argument for or against the introduction of such operations. Present regulations on commercial passenger carriage were developed prior to the availability of the turboprop engines which are now in operation.

In 1992 a study (RP/92/10) was performed to examine VCA occurrences. The report found that VCAs had increased sharply following the introduction of the AMATS system in late 1991. The aim of this report is to provide updated information on the VCA situation. As an update on the 1992 VCA report, the most recent six-month period, January to June 1994, will be examined.
