The airplane had just leveled off at 6500 feet, after departure, when the engine vibrated and lost full power. During an attempted return to the departure airport, the pilot realized that he could not make any runway and chose to make a forced landing into a corn field. The airplane was substantially damaged during the forced landing. Postaccident disassembly of the engine disclosed that the number two connecting rod had separated from the crankshaft; one of the connecting rod bolts had sheared. Inspection of the fracture surface of this connecting rod bolt disclosed there were signature marks of metal fatigue across the bolt shear face that had initiated at the surface of the bolt. The number two cylinder had been replaced about 8 hours prior to the accident; however, the connecting rod had not been removed from the crankshaft during the cylinder replacement.
Probable Cause: A total loss of engine power due to the fatigue failure of one of the number two cylinder connecting rod bolts.
