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…

In 2007 the Australian Transport Safety Bureau (ATSB) produced the inaugural edition of Australian Aviation Safety in Review as part of the ATSB's role to enhance public awareness of aviation safety. The Review has been developed to provide a readily accessible analysis of the Australian aviation sector, with a strong focus on safety trends. This publication covers all major categories of aircraft operations, from regular public transport (RPT) to general aviation (GA), and includes some information about sports aviation. Demographic and activity data on Australian aviation is provided in…

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…

Maintenance is essential to aviation safety, yet improper maintenance contributes to a significant proportion of aviation accidents and incidents. This is because a small percentage of maintenance tasks are performed incorrectly or are omitted due to human error. Examples include parts installed incorrectly, missing parts, and the omission of necessary checks. While precise statistics are unavailable, it is likely that the great majority of maintenance errors are inconsequential, however, a small proportion present significant safety threats. In comparison to many other threats to aviation…

This report provides aviation accident and incident, collectively termed occurrence, data for the period 1 January 1998 to 31 December 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 excludes non-VH registered operations in the sport aviation category, and is current as at 31 December 2008. The data will be adjusted quarterly to reflect new information received during the reporting period. Aviation Statistics Usage Survey: The purpose of this survey is to…

This study reviewed safety trends in the Australian aviation charter industry for the period 1 January 2001 to 31 December 2006. It builds on a previous descriptive study that reviewed immediately reportable matters (IRMs) for regular public transport (RPT) aviation operations. Together, charter and RPT operations make up the air transport sector in Australia. Similar to the previous report, a subset of generally more serious IRMs were reviewed including: accidents; violations of controlled airspace (VCA); breakdowns of separation (BOS) and airproxes; fire, smoke, explosions or fumes; crew…

Acknowledging the safety action already taken by the Operator, these measures have not solved the problem and the safety hazard remains. An update provided by the reporter indicates that an excessive number of bikes continue to be carried on these particular services and their presence creates an ongoing hazard to carriage occupants. Despite the problem persisting, it appears that the Operator has made an attempt to manage the situation by allocating human resources at the appropriate times. Additionally, the train staff have been given the authority to exercise discretion regarding the…
