NTSB narrative
While descending, the airplane's engine started "missing" and began to lose power. Unable to maintain altitude, the pilot declared an emergency and executed a forced landing to a field. During the landing, the nose landing gear collapsed and the outboard 4 feet of the left wing was bent upward. Examination of the engine revealed no anomalies that would have precluded normal engine operation. The reason for the reported partial loss of engine power was not determined.
Probable cause
the reported partial loss of engine power for undetermined reasons. A contributing factor was the lack of suitable terrain for the forced landing.

- 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, coordinates. 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.
