With the creation of the ATSB in July 1999, followed by the enactment of the Transport Safety Investigation Act (TSI Act) in 2003, Australia had for the first time a national body with a mandate for professional and independent rail safety investigations. In its relatively short existence, the ATSB's rail safety unit has had a significant influence on rail safety in Australia. In particular, it has been instrumental in fostering an approach that emphasises the importance of system safety, rather than just focusing on the mistakes of operational personnel. Other notable achievements of the…

The objective of the project is to analyse GPWS warnings in Australia with a view to addressing ICAO steps (e) Investigation of GPWS warnings and (f) Reduction of unwanted warnings, of the circular AN11/1.1.1993/61. CFIT accidents are the most severe aircraft accidents. These kinds of accidents occur when an otherwise airworthy airplane is inadvertently flown into the ground or water. The number of fatalities per accident is extremely high as compared to any other type of accident. They also generally result in complete destruction of the airplane. If CFIT accidents were to be completely…

Financial year 2007-08 was in many respects a watershed year. In road safety, the November election of the Rudd Government led to the move of road safety from the ATSB to the Department proper from the end of March 2008 to better align with the new Government's priorities. While I was proud to chair the National Road Safety Strategy Panel from 1999 to 2008, the establishment of a higher level Commonwealth/State body holds the promise of making further gains in reducing the nation's unacceptably high road toll. However, I was personally sad to lose the road safety branch led by Joe Motha and…

For many decades, fibre composites have been replacing traditional aluminium structures in a wide variety of aircraft types. From the first all-composite kit plane released in 1957, composites are widespread today in commercial aircraft and many other aircraft types. This is due to the cost and weight savings that materials such as glass/phenolic and carbon/epoxy offer aircraft manufacturers over aluminium, while maintaining or surpassing its strength and durability. This study provides an overview of fibre composite use in aircraft and the issues associated with its use, with a focus on…

The ATSB released this report in June 2008. Since that time, the ATSB has received comments regarding the technical accuracy of the removal of particles from high efficiency particulate air filters (page 6 of the report). This report has been amended accordingly and contains an additional reference for readers on page 10. Every year, an increasing number of people undertake air travel. Whether for business or pleasure, these journeys should be safe and enjoyable. However, there is continuing public concern about whether, or to what extent, aircraft cabins represent an increased risk of…

The quality of a safety investigation's analysis activities plays a critical role in determining whether the investigation is successful in enhancing safety. However, safety investigations require analysis of complex sets of data and situations where the available data can be vague, incomplete and misleading. Despite its importance, complexity, and reliance on investigators' judgements, analysis has been a neglected area in terms of standards, guidance and training of investigators in most organisations that conduct safety investigations. To address this situation, the Australian Transport…

The ATSB has changed the way in which aviation statistics are presented. This report represents the first in an ongoing series of reports provided in the new format. The report encompasses a rolling 10-year reporting cycle and replaces all individual spreadsheets previously available. This report provides aviation accident and incident, collectively termed occurrence, data for the period 1 January 1998 to 30 June 2008. This data was provided to the Australian Transport Safety Bureau by 'responsible persons' as defined in the Transport Safety Investigation Regulations 2003, Part 2.5. The data…

This report analyses birdstrikes reported to the Australian Transport Safety Bureau between 2002 and 2006. In Australia, over the last five years, the number of birdstrike occurrences reported annually to the Australian Transport Safety Bureau (ATSB) has risen from approximately 750 in 2002 to 1,200 in 2006. The report includes bird and bat strikes that occurred in Australian territory involving VH- and overseas registered aircraft. It excludes strikes involving non VH-registered Australian aircraft and those involving VH-registered aircraft that occurred overseas. Birdstrikes were analysed…

Each year, 'responsible persons', as defined in the Transport Safety Investigation Regulations 2003, Part 2.5, provide the Australian Transport Safety Bureau (ATSB) with reports on aviation accidents and incidents, collectively termed occurrences. These reports are used by the ATSB to assist with the independent investigation of occurrences and for identifying safety trends. This report provides aviation occurrence data for the period 1 January 1999 to 30 June 2009. The data contained herein is dynamic and subject to change pending the provision of new information to the ATSB. The data will…

This information bulletin is designed for cabin crew and will supplement your airline's cabin crew emergency procedures manual and should enhance your knowledge about what can occur during an aircraft depressurisation. Why are aircraft pressurised? Modern aircraft are designed to fly at high altitudes. For example, a Boeing 747 aircraft normally cruises at an altitude of 28,000 – 35,000 ft. This is because aircraft consume less fuel and fly in relatively smooth air, avoiding bad weather and turbulence. However, the human body is not designed to survive at such high…
