While cruising at 3,500 feet mean sea level, the engine suddenly began knocking and vibrating. Moments later, all engine power was lost. The pilot initiated a forced landing on a nearby road, but during the approach collided with a tree. An inspection of the engine revealed several holes in the upper portion of the case in the vicinity of the number 6 cylinder. Further examination revealed that both of the number 6 connecting rod bolts were broken and the rod cap was crushed and fragmented. The owner reported that the rod bolts had been in service for about 1,185 hours. The engine's total time was about 2,350 hours.
Probable Cause: a loss of engine power due to connecting rod bolt failure. The reason for the bolt failure was not determined. A contributing factor was the presence of trees in the emergency landing path.
