| Confidence Rating: |  Accident investigation report completed and information captured |
The student pilot reported that while he was performing flight maneuvers in preparation for a checkride, the engine backfired and lost partial power. He attempted unsuccessfully to regain engine power. Because he could not maintain altitude and the local terrain was tree-covered, the student pilot chose to ditch the airplane in a nearby lake. A postaccident examination of the engine revealed the No. 3 cylinder lost compression due to the seizure of the No. 3 cylinder piston rings. The No. 3 cylinder fuel nozzle was found partially clogged, which likely resulted in a lean fuel mixture and excessive heat in the cylinder and the subsequent piston ring failure. The reason for the clogged fuel nozzle could not be determined.
Probable Cause: The partial loss of engine power due to the loss of cylinder compression. The loss of cylinder compression was the result of the No. 3 piston ring failure due to excessive heat because of the lean fuel mixture from a partially clogged fuel nozzle.
