| Confidence Rating: |  Accident investigation report completed and information captured |
Shortly after takeoff the engine sustained a total loss of engine power caused by fatigue failure of the crankshaft gear, necessitating the pilot to perform an off-airport forced landing that resulted in substantial damage. The fatigue fracture initiated from multiple origins at a corner of a keyway cut in the gear. The crankshaft gear underwent magnaflux inspection and was approved for return to service associated with an engine overhaul nearly 8 years and 247 hours earlier. While there was no evidence of plating at the fatigue initiation site, it could not be determined from the available evidence whether the fatigue existed in the part at the last inspection or how fast the fatigue crack was growing.
Probable Cause: The fatigue failure of the crankshaft gear, resulting in a total loss of engine power.
