The total loss of engine power for reasons that could not be determined based on available evidence. Contributing to the accident was the pilot’s decision to turn away from a suitable emergency landing surface, his failure to maintain adequate airspeed as the airplane neared the ground, and his exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall.

The pilot's failure to maintain directional control during the landing roll in variable, gusting wind conditions, resulting in a runway excursion, and substantial damage to the airplane.
