The ATSB has released its investigation report into the
In-flight upset - Airbus A330-303, VH-QPA, 154 km west of Learmonth, WA, 7 October 2008
A Qantas Airbus A330-303 aircraft departed Singapore on a scheduled passenger transport service to Perth, WA. While the aircraft was in cruise at 37,000 ft, one of its three air data inertial reference units (ADIRUs) started outputting intermittent, incorrect values (spikes) on all flight parameters to other aircraft systems. Two minutes later, in response to spikes in angle of attack (AOA) data, the aircraft’s flight control primary computers (FCPCs) commanded the aircraft to pitch down. At least 110 of the 303 passengers and nine of the 12 crew members were injured; 12 of the occupants were seriously injured and another 39 received hospital medical treatment.
The report is a timely reminder for passengers to fasten their seatbelts during flight.
