NTSB

Probable cause: The pilot’s improper preflight fuel planning, which resulted in fuel exhaustion and the subsequent total loss of engine power.

Probable cause: The pilot’s improper landing flare, which resulted in a hard landing. Contributing to the accident were the pilot’s lack of experience and training in the accident airplane make and model.

Probable cause: The failure of both pilots to see and avoid the other airplane while in level cruise flight, which resulted in a midair collision.

Probable cause: The pilot’s failure to recover from a spin for reasons that could not be determined based on the available information.

Probable cause: The total loss of engine power due to the fuel pump’s fuel flow setting being set too high, which resulted in an excessive fuel flow to the engine.

Probable cause: A total loss of engine power for reasons that could not be determined because examination of the engine revealed no evidence of any preimpact mechanical malfunctions or failures that would have precluded normal operation.

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

Probable cause: A loss of engine power for reasons that could not be determined based on the available information.

Probable cause: The pilot’s decision to take off with insufficient runway available and his exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall.
