| Confidence Rating: |  Accident investigation report completed and information captured |
A total loss of engine power was experienced during an initial takeoff climb. A forced landing was made on a levee during which time the airplane was substantially damaged. The investigation revealed a fatigue failure of the crankshaft at the #3 main bearing journal on the Lycoming O-235-L2C engine. The nature of the failure indicated the #3 bearing spun due to undetermined reasons. The airplane had been involved in two propeller strike incidents. The engine was not overhauled after either of these incidents. Lycoming Service Letter L163C recommends removal, disassembly and inspection of the engine after propeller strikes.
Probable Cause: The fatigue failure of the crankshaft which resulted from a spun bearing and the low altitude at which the loss of engine power occurred. A factor in the accident was the embankment on which the airplane was landed.
