| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot descended into the airport traffic pattern from 4,200 feet AGL with the engine idled, mixture rich, and carburetor heat on. When engine power was added to adjust the landing approach, the engine failed to respond. Because of high surface winds, the pilot was unable to glide to the runway and an off-airport landing was made and the aircraft nosed over. Inspection of the engine revealed carbon buildup under the intake and exhaust valves and low compression. After staking the valves compression returned to normal. The second pilot said they had not cleared the engine during the descent as required by the engine Operator's Manual.
Probable Cause: the pilot's failure to clear the engine during an idle power descent, as required by the engine manual.
