NTSB

Probable Cause: The pilot’s failure to maintain the proper glidepath during final approach, which resulted in a collision with the approach lights short of the runway. Contributing was the pilot’s distraction due to the cabin door opening.

Probable Cause: The pilot’s failure to ensure adequate airplane performance before taking off from a significantly shorter runway than originally planned for.

Probable Cause: The pilot’s improper preflight inspection which resulted in a loss of engine power due to fuel contamination (water).

Probable Cause: An in-flight fire that resulted from an inadequate 100-hr inspection, which failed to detect and correct improper electrical cable routing in the engine compartment.

Probable Cause: The pilot’s failure to maintain control during a forced landing following a loss of engine power. Contributing was the pilot’s failure to feather the left propeller following the loss of engine power.

Probable Cause: The pilot’s delay in performing a go-around after a likely encounter with low-level wind shear, resulting in a hard landing. Contributing to the accident were the pilot’s failure to recognize the severity of the actual and forecasted weather near the airport and his continued approach to the airport with a thunderstorm and associated convective activity.

Probable Cause: The pilot’s exceedance of the airplane’s critical angle of attack during initial climb, which resulted in an aerodynamic stall/spin and loss of control that the pilot did not recover from.
