The ATSB investigation into the fatal Aero Commander accident on 19 February 2004, 58 km NNW of Hobart is focusing on the reason for an overload failure of the wings in flight. The ATSB interim factual Report finds that the wreckage pattern was consistent with the aircraft having sustained an in-flight structural failure of both wings and the tailplane. The outboard left and right wing sections had separated from the aircraft at similar positions along the respective wings and in a downward direction. However, there…

Failure to keep a proper lookout by either vessel has been identified as the immediate cause of the ninth collision in five years between a fishing vessel and a ship off the Australian coast. In the early hours of 21 August 2003, the fishing vessel Jenabar collided with the bulk carrier Lancelot off Diamond Head on the New South Wales coast. The report on the collision by the Australian Transport Safety Bureau (ATSB) also identifies that over-reliance on board Lancelot on information from the automatic radar plotting aid contributed to the collision. On…

The ATSB investigation Preliminary report into the accident in which six lives were lost when a privately operated Piper Cheyenne aircraft crashed near Benalla, Victoria, on 28 July 2004, found that the aircraft was off course for a substantial period. The aircraft departed Bankstown, NSW that morning, and travelled via Jervis Bay. The pilot then contacted air traffic control requesting a track from abeam Ulladulla to Benalla. The route flown did not pass directly over any ground based navigation aids and the pilot…

Given the heightened interest, the ATSB has released an interim REPORT on progress with its investigation into the tragic Benalla fatal accident, emphasising its complexity due to destruction of the aircraft and the need to carefully address all the safety issues. The ATSB Preliminary REPORT into this six-fatality accident in a Piper Cheyenne was released on…

The Australian Transport Safety Bureau (ATSB) has found that fatigue cracking in the blade slots of a high-pressure turbine disk led directly to the uncontained failure of the left engine of a Boeing 767 aircraft that occurred near Brisbane on 8 December 2002. The aircraft was operating a scheduled passenger service to Auckland, New Zealand and was forced to return to Brisbane airport after the failure. Damage to a wing leading-edge flap from engine debris and the weight of the fuel being carried for the trans-Tasman flight led the flight crew to perform a prepared emergency landing, during…

The Australian Transport Safety Bureau (ATSB) has advised that the door that fell from a Raytheon Beechcraft King Air B300 aircraft on Tuesday 7 September 2004 has been located. The ATSB would like to thank media outlets for their cooperation in publicising our request for assistance in finding the cabin door. The door was located to the south-west of Theodore, Central Queensland. With the assistance of the Queensland Police Service the door will be delivered to the ATSB's laboratories in Canberra for examination. The ATSB will now be in a much better position to determine why the door fell…

After allowing for activity levels, ATSB research indicates that Robinson R22 helicopters have a similar safety profile to other comparable helicopters. This study was prompted by increasing concerns about light utility helicopter safety in Australia. Light utility helicopters make up half the registered fleet yet were involved in 72 per cent of all helicopter accidents between 1985 and 2003. The report compared accident involvement and accident rates of four helicopter models; Robinson R22, Bell/Agusta/Kawasaki 47G, Hughes/Schweizer 269 and Hiller UH-12E…

The ATSB's aviation safety survey of commercial pilots, Common Flying Errors, has revealed that, violations of standard operating procedures were more prevalent in general aviation and were involved in 11.8% of all events. The survey asked pilots to identify the main factors contributing to errors and the defences they used to recover. Most errors occurred en route, distantly followed by flight preparation errors. All categories of pilot experienced errors while executing procedures en route, such as not completing their landing checklist, and misprocessing information from their operational…

The failure of officers to use modern navigation bridge management principles was the major factor in the grounding of the Bahamas registered passenger ship Astor during the ship's departure from Townsville at around 7 pm on 26 February 2004, according to an Australian Transport Safety Bureau (ATSB) investigation report released today. The ATSB report into the Astor grounding released today states that the ship grounded on its port side as it was turning from Townsville harbour into Platypus Channel. The ship heeled…

A study by the ATSB has shown that just under half of the general aviation fatal accidents in the ten year period between 1991 and 2000 were Uncontrolled Flight Into Terrain (UFIT) accidents, where an intact aircraft collided with a stationary obstacle or terrain after an in-flight loss of control had occurred. In more than half of the UFIT fatal accidents an event that was either not averted, or not managed appropriately by the pilot, or was not within the pilot's control, preceded the loss of control. However, in the vast majority of UFIT fatal accidents that occurred during low-level…
