Air Crash Investigation: 2009 Schiphol Disaster Turkish Airlines Flight 1951 was a passenger flight which crashed during landing to Amsterdam Schiphol Airport, Netherlands, on 25 February 2009, killing nine passengers and crew including all three pilots. The aircraft, a Turkish Airlines Boeing 737-800, crashed into a field approximately 1.5 kilometres north of runway 18R, prior to crossing the A9 motorway inbound, at 9:31 UTC (10:31 CET), having flown from Istanbul, Turkey. The aircraft broke into three pieces on impact. The wreckage did not catch fire. A preliminary investigation found that the crash was caused primarily by the engine’s automated reaction which was triggered by a faulty radio altimeter, which had failed twice in the previous 25 hours. This caused the autothrottle to decrease the engine power to idle during approach and the crew noticed this too late to take appropriate action to increase the throttle and recover the aircraft before it stalled and crashed.
