NTSB Accidents

Probable cause: The pilot’s failure to remove the engine cowl plugs during preflight, which resulted in excessive engine cylinder head temperatures during climb and a total loss of engine power.

Probable cause: An in-flight collision with a bird while on downwind.

Probable cause: The pilot’s inadequate preflight inspection, which resulted in undetected water in the fuel system and a total loss of engine power during the initial climb.

Probable cause: The accumulation of carburetor ice while operating at a reduced engine power setting, which resulted in a total loss of engine power on approach and a subsequent forced landing on unsuitable terrain.

Probable cause: The pilot’s improper decision to return to the runway instead of landing straight ahead when the engine lost power and his failure to maintain adequate airspeed while maneuvering for an emergency landing, which resulted in an exceedance of the airplane’s critical angle of attack and an aerodynamic stall. Contributing to the accident was the pilot’s failure to properly secure the left main fuel tank cap after refueling, which resulted in a loss of engine power due to fuel starvation during the takeoff climb.

Probable cause: The failure of the weld that connects the left main landing gear and the axle during the takeoff roll.

Probable cause: The pilot’s failure to secure the right fuel cap during the preflight inspection, which resulted in fuel exhaustion, a total loss of engine power, and an off-airport hard landing.

Probable cause: The student pilot’s decision to take off from a partially-lit grass runway in dark night, marginal visual flight rules conditions, which resulted in spatial disorientation, an exceedance of the airplane’s critical angle of attack, and an aerodynamic stall.
