NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
According to the pilot, 20 minutes after departure, while in cruise flight, the airplane's engine began to 'run rough' and vibrate. He reduced power in attempts to dampen the vibration and initiated a precautionary landing to a nearby airport. As the airplane touched down the pilot noticed a dirt embankment, which was approximately 2 feet high, running along the runway centerline. Subsequently, the airplane contacted the embankment, exited the runway surface, struck a fence and trees, and came to a stop upright. A test run of the engine revealed that the engine would not run with the ignition switch in the LEFT position, and would run rough in the BOTH position. Examination of the left magneto revealed that the resistance was less than 16,000 ohms, failing to meet the manufacturer's specifications. Additionally, the number 3, 4, and 5 rear spark plugs exhibited oil and lead deposits.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The failure of the left magneto, which resulted in a partial loss of engine power. Factors were the fouled number 3, 4, and 5 rear spark plugs and the lack of suitable terrain for the precautionary landing. Full narrative available
