NTSB narrative
The pilot was ferrying the newly-purchased agricultural airplane to his home airport. Approximately 1 hour since fueling, the engine lost power. Despite the pilot's attempts to restart the engine, he was forced to land the airplane in an agricultural field. A postaccident examination of the airplane and engine did not reveal any mechanical anomalies that would have resulted in a loss of engine power.
Probable cause
A loss of engine power for undetermined reasons.

Source notes (4)
- 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.
- API snapshot SHA-256: 745fbdfd60c69526832aae0cc13d9b2bc1c45b7f8ad609aa50bcbe65ec61eb2f; retrieved 2026-09-15T13:54:01.807Z.
