A Failure to Comply incident is defined as an air safety incident in which flight crew fail to follow an ATS clearance in controlled airspace. During 1994 BASI recorded an increase in the frequency of incidents involving failures to comply with ATS clearances. This trend continued in 1995 and the largest increase appeared to be associated with the introduction of new arrival and departure procedures at Sydney airport. The Bureau conducted a preliminary study to confirm these trends and concluded that a comprehensive study was necessary. This report draws on data collected during the…

Accident, incident and anecdotal evidence indicate that the introduction of new technology to aviation has generally resulted in benefits to safety and efficiency (Norman and Abbott 1988). Information published by Boeing Commercial Airplanes indicates that in general, accident rates have been declining with each successive technological advance over the last thirty years (Boeing 1988). However, new technology has also resulted in a range of new human factors and operational difficulties. New tools invariably change the way a job is done and new aircraft are no exception. The work of pilots…

A VCA occurs when a pilot enters controlled airspace without a clearance. Controlled airspace is a section of airspace surrounding an airport with a tower, and/or airspace up to a certain altitude overlying Australia. This airspace may or may not be radar monitored. The controller needs to be aware of all aircraft within hisher section of controlled airspace so as to provide a complete traffic service. Pilots are required to request a clearance before entering the airspace.

The history of helicopters in Australia did not begin until after World War II. Although in 1943 the Amy planned to use helicopters for reconnaissance work in New Guinea, it was not until 1948 that the R AAF received its first helicopters, Sikorsky S51s. Civil helicopters followedin 1956, with the import of a Bristol Sycamore for ANA and a Hiller 12c for TAA early in that year. In May 1956 ANA'S helicopter began operating in Tasmania.

This study analyzed occurrences involving fuel starvation - the state in which the fuel supply to the engine is interrupted although there is adequate fuel onboard the aircraft, and fuel exhaustion - the state in which the aircraft has become devoid of usable fuel. Fuel starvation has been a more common type of occurrence; however, the probability of the occurrence resulting in an accident has been greater for fuel exhaustion. starvation accidents and 8 fuel exhaustion accidents per annum in Australia since 1969. Fuel-related engine failures have constituted 34% of all engine failure…

We understand that any accident that results in a serious injury or loss of life can have profound effects. A fatality begins a complex process of grieving for those close to the individual(s) involved. Families and friends naturally want to know why the accident happened, and how to prevent someone else having to experience such loss. This page and accompanying brochure attempt to answer some of your questions about a transport safety investigation conducted by the Australian Transport Safety Bureau (ATSB) where there has been a fatality. The ATSB is governed by a Commission and is entirely…

Non-factory amateur-built and experimental (ABE) aircraft are a popular alternative to general aviation aircraft. In Australia, there is little comprehensive data on these aircraft and what people do when building or buying them second-hand. Key players in this part of aviation were consulted in developing a survey to better understand these aircraft builders and owners. The survey was distributed electronically and in hard copy to owners of VH-registered ABE aircraft, and about 50 per cent of active ABE aircraft owners answered the survey. It focussed on choice of aircraft, construction and…

The aim of this study was to provide information to the flying community concerning those common errors they perceived to be most detrimental to flight safety. The ATSB sent the 'Aviation Industry Safety Survey' to 5000 commercial pilots throughout Australia in November 2003. The survey asked pilots about their safety experiences during the previous year and to report the most serious error they made or saw during that time. They were also asked to describe briefly what they thought were the main factors contributing to the error and how the situation was recovered. Demographic information…

While most runway excursions are relatively minor with no serious injuries or aircraft damage occurring, they do have the potential to pose a serious risk to public safety and infrastructure. This has been illustrated by several significant runway overruns around the world in 2007 and 2008, resulting in hundreds of on-board fatalities, as well as ground fatalities and significant property damage in communities adjacent to airports. Further analysis of the Ascend World Aircraft Accident Summary set of 120 runway excursions on landing involving commercial jet aircraft between 1998 and 2007 (…

In 2009, the Australian Transport Safety Bureau (ATSB) produces its third edition of Australian Aviation Safety in Review as part of its role to enhance public awareness of aviation safety. This Review has been developed to provide a readily accessible analysis of the Australian aviation industry, with a major focus on communicating the key safety trends. This publication covers the major aircraft operation categories of passenger transport (regular public transport and charter) and general aviation. Sport and recreational aviation is also discussed, as is the burgeoning trend towards amateur…
