NTSB narrative
The pilot departed for the seventh of fifteen planned aerial application flights that day; the engine subsequently lost total power. The pilot conducted a forced landing to a rice field. A fuel sample drained from the airplane following the accident was cloudy and contained floating debris. Postaccident examination of the fuel system revealed a significant amount of debris, including grass, leaves, insects, and dirt, in the fuel control filter and airframe filter bowl. Further examination of the fuel filter assembly revealed that the inlet and outlet holes of the filter housing, as well as the filter inlet hose, contained debris of sufficient quantity to result in a disruption of fuel flow to the engine. Whether the pilot conducted a preflight inspection could not be determined; however, a fuel sample taken prior to the flight would likely have displayed contamination.
Probable cause
A total loss of engine power due to debris contamination of the fuel system. Contributing to the accident was the pilot's inadequate preflight inspection.

- 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.
