NTSB narrative
The pilot reported that the engine experienced a partial loss of power while the airplane was in cruise flight. After the pilot unsuccessfully attempted to restore engine power, he made a forced landing to a cornfield. Postaccident examination of the dual magneto system revealed that the four screws designed to hold the magneto points in their operational positions were loose, which caused both magneto points to remain in the closed position as the center cam was rotated and likely resulted in the partial loss of engine power. Airplane maintenance records indicated that the airplane had been flown 8 hours since its last annual inspection about 5 1/2 months before the accident. No further information about the maintenance was available.
Probable cause
A partial loss of engine power due to a failure of the dual magneto system. Contributing to the accident was the improper maintenance of the duel magneto system.

- 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.
