NTSB narrative
The private pilot reported that the purpose of the flight was to apply pesticides to a field. The takeoff and transit to the work area were normal; however, after he had conducted a few spray runs, the engine power began to degrade. The pilot decided to fly the airplane back to the airport. The engine power continued to degrade, so the pilot moved the fuel boost pump switch to the "on" position; however, the engine then lost total power, and the pilot was forced to land the airplane in a cornfield about 3 miles from the airport. During the forced landing, the left main landing gear collapsed, and the airplane ground looped, which resulted in substantial damage to the fuselage and wings. A postaccident examination of the fuel system and the engine revealed no anomalies.
Probable cause
The total loss of engine power for reasons that could not be determined because postaccident examination of the engine and fuel system revealed no anomalies.

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. 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.
