Following three breakdown of separation occurrences in the airspace of the Sydney Terminal Area (TMA), the Bureau of Air Safety Investigation (BASI) initiated a systemic investigation into the common factors underlying those occurrences. The investigation commenced on 22 June 1998 and was completed by 31 July 1998. Three further occurrences were identified during the course of the investigation. The systemic investigation has identified safety deficiencies primarily related to the management of change, and the rate and complexity of change faced by air traffic controllers operating in the…

Regional airline operations globally have expanded over the past decade for various reasons, including filling gaps left by legacy carriers who have reduced services on unprofitable routes, opportunities provided through other cost based market rationalisations, and the introduction of new and more capable regional type aircraft. Very little formal research has been done in Australia or overseas to assist with the development of safety models and tools for regional airline operations. Regional Express (REX) is a relatively new airline that was created by merging two separate and culturally…

This aim of the study was to provide objective data to inform fatigue risk-management processes by determining the quantity and quality of sleep obtained by airline pilots during transcontinental back of clock operations, and any changes to subjective fatigue and neurobehavioral performance during these sectors. Typical transcontinental back of clock route pairings involve a departure close to midnight Perth local time, with a dawn arrival into an East-coast city such as Melbourne, Sydney or Brisbane. In many instances this first sector is followed by a second sector to another east-coast…

This study provides a systematic analysis of the types of human error occurring in Australian civil aviation accidents. It also compares these results against a larger sample of accidents occurring in the United States. Inevitably, all humans make errors. But safety can be enhanced when the number and consequences of these errors are reduced. This paper aims to enhance aviation safety through extending our knowledge of aircrew errors. While the types of accidents and flying operations varied slightly between Australia and the US, the pattern of aircrew errors were remarkably similar. Skill-…

The Robinson R22 helicopter is the most common model of rotary-wing aircraft on the Australian register and has been a popular choice for private operations, flying training and various types of aerial work activity. The R22 has a relatively good safety record compared with other light piston-engine helicopters in Australia based on activity levels. The R22 is also the favoured type for aerial stock mustering operations - a uniquely Australian application that supports the local beef cattle industry. Despite its popularity in this type of work, little was known about the helicopter's…

The purpose of this report was to examine the relationship between ageing aircraft and flight safety, to determine the chronological age of the Australian aircraft fleet, and to review current and future directions for the management of ageing aircraft. Age can be managed by retiring the aircraft and purchasing a newer aircraft or through adequately maintaining ageing aircraft through additional and specific maintenance. This requires cooperation between regulators, manufactures, maintainers, operators, and owners. Continuing airworthiness programmes and Supplementary Inspection Programmes…

Each year the United States' Aircraft Owner's and Pilots Association (AOPA) Air Safety Foundation releases a report summarising the accident trends and factors for general aviation (GA) for the previous calendar year. The Nall Report has established itself as one of the aviation community's benchmark reports and its release is anticipated across the industry. The report provides essential data in an easy-to-read format, giving a broad overview of the state of general aviation and safety trends in the US. As part of the Australian Transport Safety Bureau's (ATSB) mission to enhance public…

The details of 75 fatal aeroplane accidents were extracted from the BASI database. The largest proportion (36%) of the accidents occurred on private/business flights. The three most frequent first occurrences in accidents were loss of control; collision with terrain (control unknown); and wirestrike. Most accidents had more than one contributing factor. Over 70% of the accidents involved pilot factors. The most common pilot factors related to poor judgement and decision making. In recent years, BASI has recognised that while pilot factors are of great importance, accidents frequently have…

A review of existing Commonwealth, State and Territory legislation relating to the transport of dangerous goods by rail, was undertaken. The review provides an overview of the status, coverage and adequacy of existing rail dangerous goods transport legislation. The review also examines options for the development of a nationally uniform regulatory regime for rail dangerous goods transport operations. Issues relating to inter-modal harmony with the road transport sector, and legislative options to achieve uniformity are also discussed. The review concludes that a nationally uniform rail…

Human error is recognised as an important issue in fields as diverse as medicine, mining and shipping, and to some extent aviation. Although the human element has long been recognised as important in the cockpit, its role in aircraft maintenance has been largely overlooked. According to Boeing figures 12% of major aircraft accidents involve maintenance, and 50% of flight delays in the US are caused by maintenance errors. In response to a worldwide lack of information on the issue, in late 1998 the Bureau distributed a safety survey to all licensed aircraft maintenance engineers in Australia.…
