Aircraft Accident/Incident Report
Lewistown, Montana 59457
Friday, May 16, 2003 15:30 MDT
NTSB Narrative Summary Released at Completion of Accident
While reducing power on left downwind to configure the airplane for landing, the engine began to run rough. The pilot reapplied power and the engine smoothed out. Reducing power a second time, the engine ran rough again. After reapplying power the pilot raised the nose to slow to landing gear operating speed. After lowering the landing gear and extending the flaps to 10 degrees, and seeing he had the runway made, the pilot turned base, reduced power, and the engine quit. The airplane landed 300 to 350 feet short of the runway on the grassy extension to the runway, subsequently proceeding through a rocky area which was approximately 6 inches below the level of the runway. An FAA inspector reported that the distance from the threshold ground level to the overrun pavement surface of 6 inches exceeds the recommended maximum of 3 inches, and contributed to the substantial damage of the aircraft. The impact with the lip of the runway knocked the nose gear back, damaged the right main gear, and bent the propeller. A post-accident examination of the engine revealed no anomalies which would have prevented normal operation.
NTSB Probable Cause Narrative
The loss of engine power for undetermined reasons. The condition of the runway overrun was a factor.
