Area navigation global navigation satellite system (RNAV (GNSS)) approaches have been used in Australia since 1998 and have now become a common non-precision approach. Since their inception, however, there has been minimal research of pilot performance during normal operations outside of the high-capacity airline environment. Three thousand five hundred Australian pilots with an RNAV (GNSS) endorsement were mailed a questionnaire asking them to rate their perceived workload, situational awareness, chart interpretability, and safety on a number of different approach types. Further questions…

Transport accidents are a leading cause of injury, both fatal and non-fatal. The primary purpose of this publication is to provide a broad overview of serious injury due to transport accidents in Australia in the one-year period 2003-04, the latest year for which data are available. Serious injury is defined for this report as an injury which results in the person being admitted to hospital, and subsequently discharged alive either on the same day or after one or more nights stay in a hospital bed (i.e. deaths are excluded). This report presents estimates of the numbers of persons seriously…

Transport accidents are a leading cause of injury, both fatal and non-fatal. The primary purpose of this publication is to provide a broad overview of serious injury due to land transport accidents in Australia in the one-year period 200304, the latest year for which data are available. The main focus is on accidents involving road vehicles travelling on public roads (called travelling in traffic). Road vehicles include motor vehicles, pedal cycles and other road vehicles such as trams, animals or animal-drawn vehicles (when they travel on the road). Serious injury is defined for this report…

The ATSB carried out a safety deficiency investigation in accordance with powers under section 19CB (1) (d) of the Air Navigation Act 1920. SAFETY DEFICIENCY An allegation was made to the ATSB that Australian registered Boeing 747-300 aircraft operating from Bangkok airport in Thailand were failing to meet take-off performance requirements. A 'specified' flight was cited as demonstrating that the aircraft had not complied. Comprehensive analysis of data from the 'specified' flight, as well as data from other flights departing Bangkok under similar conditions, was undertaken. Documentation…

This report was tabled in the Australian Parliament on 23 November 1999 Class G airspace (or uncontrolled airspace) has the lowest level of service and the fewest restrictions on aircraft operations. In Australian Class G airspace, third-party directed traffic information is provided to pilots of aircraft operating under the instrument flight rules. There have been a number of attempts to change the operation of Class G airspace since its introduction in 1995. As part of the Airspace 2000 program, the Civil Aviation Safety Authority (CASA) decided to conduct a 'Class G demonstration'…

Executive Summary The partial wreckage of a Cessna 206 aircraft was recovered from an area in the Gulf of Carpentaria, near where an aircraft of this type disappeared on 24-November 1999 (ATSB Occurrence number 199905562). Photographs and video footage of the wreckage were supplied to the ATSB and reviewed with a view to gathering further detail regarding the accident. The ATSB subsequently requested that the propeller and attitude indicator instrument from the aircraft be shipped to the bureau's Canberra laboratories for further study and analysis. On the basis of damage to several aircraft…

Reciprocating-engine powered low-capacity transport aircraft (8 to 10 passengers) provide an important public transport connection throughout regional Australia. In the period January 2000 to December 2005, twenty powertrain structural failures of high-power (300 to 375 brake horsepower) horizontally-opposed, reciprocating engines were associated with air safety occurrences reported to the ATSB. These occurrences ranged in severity from; in-flight engine shutdown; engine failure and forced landing; engine failure combined with in-flight fire and fracture of both upper engine mounts; to the…

The reporting of aviation safety occurrences enables the Australian Transport Safety Bureau (ATSB) to investigate accidents and serious incidents and monitor safety through the analysis of any trends. On 1 July 2003 the Transport Safety Investigation Act 2003 came into effect, introducing the terms immediately reportable and routine reportable matters (IRMs and RRMs, respectively). This report examines trends in IRMs that involved regular public transport operations and provides a context for interpreting any changes over time. The aim is to inform the aviation community of any important…

The purpose of this publication is to provide a national overview of serious non-fatal injury in Australia due to transport accidents involving a railway train in the period 1999-00 to 2003-04, including level crossing accidents. The definition of transport injury used in this report excludes injuries given an external cause of intentional self harm, assault or undetermined intent (terms that are defined in the report). This report includes all injuries that were serious enough to require hospitalisation but did not result in death. Publication available from the Australian Institute of…

The 1995 House of Representatives Standing Committee on Transport, Communications and Infrastructure Plane Safe Report (Morris, 1995), found that 'a paucity of information' and 'an absence of safety indicators' were features of the low-capacity RPT sector of the Australian aviation industry. A Preliminary Information Paper published by BASI in 1996 concluded that a range of safety issues warranting further research existed within the regional airline industry. BASI then appointed a research team to comprehensively investigate the level of safety in the regional airline industry. After a study…
