NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The airplane was climbing through 9,000 feet, after departure, when the engine lost total power. The pilot attempted to restart the engine, but was unsuccessful and executed a forced landing north of the departure airport. Postaccident examination of the airplane revealed that there was a hole in the engine crankcase behind the #2 cylinder and the #1 piston pin had separated at its midpoint. Further, examination of the engine revealed that the #1 piston pin failed as a result of fatigue and the #1 connecting rod bushing (piston pin end) was found fragmented in the oil sump.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The separation of the #1 piston pin due to fatigue, which resulted in a total loss of engine power. A factor was the lack of suitable terrain for the forced landing.
