| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that he was in cruise flight when the engine began to run rough and lose power. Shortly thereafter, the engine lost total power and the pilot maneuvered the airplane to a nearby field to perform a forced landing. Just before touchdown, the airplane collided with a barbed wire fence and subsequently landed hard. Examination and disassembly of the 2-cylinder engine revealed that the right and left cylinder intake valves were not properly seating with the cylinder heads when the valves were in the closed position. The pilot reported this condition would likely cause low cylinder compression and a loss of engine power. No other anomalies were noted with the engine.
Probable Cause: The loss of engine power due to low cylinder compression.
