NTSB narrative
During a dual instructional flight, the engine lost power, while the airplane was at 600 feet AGL, on a downwind leg for landing on runway 30. The flight instructor elected to land downwind on runway 12, which was a 2,700 foot grass runway. The airplane touched down past the midfield point. Braking on the wet grass was minimal, and the airplane overran the end of the runway, went through two fences and nosed over, coming to rest in the inverted position. Examination of the engine revealed that an exhaust valve had failed.
Probable cause
failure of an engine exhaust valve, which resulted in a loss of engine power, a forced landing, and subsequent damage to the airplane. Factors relating to the accident were: the tailwind, and the wet grass runway.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
