Aircraft Accident/Incident Report

Panama City, Florida 32406
Friday, May 1, 1998 13:00 CDT

NTSB Narrative Summary Released at Completion of Accident

The airplane experienced a catastrophic engine failure, and the pilot executed an emergency landing near Panama City, Florida. During the flare, the left wing impacted a utility pole causing substantial damage to the airplane. Examination of the engine revealed that the crankshaft had fractured at the connection rod thrust surface adjacent to the front fillet radius of No. 6 crankpin journal. Metallurgical examination concluded that the crankshaft fractured in fatigue at the connection rod thrust surface, adjacent to the front fillet radius of the No. 6 crankpin journal due to high stress. However, exact cause of the high stress remains undetermined.

NTSB Probable Cause Narrative

The engine crankshaft fracturing, leading to total powerplant failure. Contributing to the severity of the accident was a utility pole.
