Narrative:The pilot reported a loss of engine power during cruise flight. He elected to land in the only open space available, which was comprised of rising terrain. During the approach to the field, the left wing dropped and the airplane turned to the left before impact. A postaccident examination of the number one cylinder exhaust port revealed an accumulation of carbon. The number one cylinder's spark plug could be loosened by hand in indication that it was not properly secured prior to impact; removal of that plug revealed that it exhibited a fouled appearance. The engine's maintenance manual indicated that the spark plugs are to be tightened on a cold engine to 240-inch pounds of torque. The airplane's airworthiness was maintained by the owner/pilot under a conditional maintenance program.
Probable Cause: A loss of engine power due to the improper torquing of the number one cylinder's spark plug as a result of inadequate maintenance.
