Rockwell Grand Commander 680

After takeoff, the pilot transmitted to ATC controllers that he had lost power in an engine. He made a steep turn to the left back toward the airport, then a right turn toward the runway. The aircraft's nose dropped in the right turn, and the aircraft crashed nose first on a taxiway. 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. 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.'
