NTSB Accidents

Probable cause: The pilot’s exceedance of the biplane’s critical angle of attack during initial climb, which resulted in an aerodynamic stall and collision with trees.

Probable cause: The pilot receiving instruction’s failure to maintain directional control during landing.

Probable cause: The student pilot’s overpriming of the engine and the flight instructor’s delayed remedial action, which resulted in an engine fire.

Probable cause: The pilot’s improper preflight fuel planning, which resulted in a loss of engine power due to fuel exhaustion.

Probable cause: The pilot’s exceedance of the airplane’s critical angle of attack during a go-around. Contributing to the accident was the pilot’s decision to attempt to close a passenger door during a critical phase of flight.

Probable cause: The flight instructor’s failure to ensure that the wing flaps were properly configured for takeoff, which resulted in an aerodynamic stall and loss of control during the initial climb.

Probable cause: The failure of a connecting rod small end bushing, which resulted in a loss of engine power.
