Accident Sequence
After takeoff, the pilot transmitted to air traffic controllers that he had lost power in an engine. He made a steep left turn back toward the airport, then a right turn toward the runway. During the right turn, the aircraft's nose dropped, and the aircraft crashed nose-first on a taxiway.
Post-Crash Examination
Post-crash examination of the aircraft structure and flight control systems revealed no preimpact failure or malfunction. The left propeller was found in the feathered position, and the right propeller was found in a high blade angle. The right propeller had damage consistent with the engine operating. Teardown examination of the engines and propellers showed no findings that would have resulted in engine or propeller malfunction or failure.
Pilot Experience
At the time the aircraft was purchased by the pilot in March 1996, he had not flown for about 10 years. Since purchasing the aircraft, he had logged 2.5 hours of transition/checkout in the airplane and had flown it for a total of about 22 hours, mostly on sightseeing flights.
Probable Cause
The official probable cause was the failure of the pilot to maintain minimum control speed, while returning to the airport for a precautionary landing, following a reported loss of power in one engine, which resulted in a loss of aircraft control and an uncontrolled collision with the terrain. Factors relating to the accident were: loss of power in the left engine for undetermined reason(s), and the pilot's apparent lack of familiarity with single engine operation in the make and model of aircraft.
