Confidence Rating: Accident investigation report completed and information captured
The airplane collided with terrain during an off airport forced landing after the failure of the propeller pitch change control during initial climb after an aborted landing. The propeller blades remained in the high-pitch, low-rpm setting, and did not provide sufficient power to sustain flight. The pilot landed the airplane about 1.5 miles from the airport in open desert terrain. The pilot felt that the propeller shaft extension mechanism failed prior to his landing approach at the airport, resulting in a loss of propeller control.

Probable Cause: failure of the propeller shaft extension mechanism resulting in a loss of power, and the pilot's failure to attain the proper touchdown point.
