Air Asia Report: Distraction, Crew Miscommunication Led To Stall
The string of incidents that led to the crash of Air Asia Flight QZ8501 on December 28 last year began with a mechanical malfunction that had gone unresolved despite having failed 23 times, investigators said in their final report (PDF), issued today by Indonesia's National Transportation Safety Committee. But in trying to cope with the malfunction, the captain issued "ambiguous commands" to the first officer, and failed to take over the controls, the report concludes. The Airbus A320 climbed to 38,500 feet, rolled 104 degrees to the left, then stalled and lost altitude at a rate of up to 20,000 feet per minute. The airplane crashed into the Java Sea, killing all 162 on board.
