NTSB narrative
The commercial pilot had refueled and reloaded chemical and departed the airport en route to his third spray mission of the day when the aircraft lost power. The pilot selected an open field next to the cane field that he intended to spray and set up for his forced landing. When the airplane touched down the wheels sank into the mud and nosed over coming to rest inverted. The pilot was uninjured. The airplane sustained substantial damage to the wings and wing struts. The pilot stated in the pilot operator report that water was found in the fuel resupply truck and in the airplane fuel tanks.
Probable cause
The loss of engine power due to fuel contamination. Contributing to the accident was the unsuitable muddy 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. 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.
