Probable cause: The engine’s excessive cylinder head temperatures and the subsequent seizing of the engine, which resulted from an engine control unit that caused the engine’s fuel-air mixture to be too lean.
NTSB Accidents
Hard landing bends 172
Probable cause: The pilot’s improper landing flare, which resulted in a hard, bounced landing.
Fuel starvation leads to Mooney crash
Probable cause: The pilot’s inadequate preflight and in-flight fuel management, which resulted in an intermittent loss of engine power due to fuel starvation.
Backcountry landing damages RV-9’s wings
Probable cause: The pilot’s selection of an unsuitable taxiway, which resulted in the wings striking hidden fence posts.
Failure to maintain yaw control ends in crash
Probable cause: The pilot’s failure to maintain yaw control and the exceedance of the airplane’s critical angle of attack in the traffic pattern, which resulted in an aerodynamic stall/spin.
Pilot’s first landing in Pietenpol ends in nose-over
Probable cause: The pilot’s excessive rudder and brake applications during landing, which caused the airplane to nose over.
Piper stalls during takeoff from industrial truck yard
Probable cause: The pilot’s failure to attain adequate airspeed during the short field takeoff, which resulted in an exceedance of the airplane’s critical angle of attack and an aerodynamic stall.
Bird comes ‘out of the sun’ to hit Cessna 172
Probable cause: An in-flight collision with a bird.
