Aircraft Accident/Incident Report

Clarendon, Texas 79226

NTSB Narrative Summary Released at Completion of Accident

While in cruise flight, the pilot noticed smoke emanating from the engine and entering the cockpit. The pilot secured the engine and executed a forced landing to a field. During the forced landing, the airplane impacted a fence, trees, and came to rest upright. Examination of the engine revealed the number six cylinder was partially separated from the crankcase, and several of the cylinder fasteners, deck studs and through-bolts, were fractured. Metallurgical examination of the fracture surfaces by the manufacturer revealed evidence of fatigue and overload signatures. Fretting was noted on the cylinder and crankcase mating surfaces. Hardness of each of the deck studs and through-bolts met manufacturer's specifications. No additional anomalies were noted with the engine that would have precluded normal operation.

NTSB Probable Cause Narrative

the loss of engine power due the separation of the number six cylinder as a result of a fatigue failure from the loosening of the cylinder attachment hardware.
