Computer-Related Incidents with Commercial Aircraft

Transasia Airlines A320, Taipei-Sungshan Airport, Taiwan

18 October 2004

Synopsis The aircraft landed at Taipei-Sungshan with one thrust lever, on an engine on which thrust reverse was INOP, not reduced to idle (indeed, at 22.5 degrees thrust lever angle, the lever was left near the Climb detente). Reverse thrust was applied on the other engine. Spoilers did not deploy (it requires both thrust levers to be in idle, or reverse, or one in reverse and one in idle, to do so). Manual braking was delayed. The aircraft overran the runway. The aircraft was damaged, but no one was killed, and the aircraft is still in service. Here is the Report.
