NTSB narrative
The pilot took off 50 minutes to 1 hour before the accident, and was spraying a field at the time of the accident. He reported that on the last pass, as he was pulling up, the engine lost power in a left turn. He performed a forced landing onto rough and uneven terrain; and the aircraft was substantially damaged. The aircraft salvage crew who recovered the aircraft reported that they found 3 gallons of fuel in the aircraft's left wing tank and no fuel in the right wing tank (the aircraft has a 33-gallon tank in each wing, of which 6.5 gallons in each tank is unusable.)
Probable cause
The pilot's mismanagement of the fuel which led to fuel exhaustion. A related factor was unsuitable terrain.

Source notes (5)
- 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.
- API snapshot SHA-256: 53067cfe60efd85095aa7c5674e4c0c8e832689a224b64c8c59d665e717ffe5c; retrieved 2026-09-22T17:58:48.992Z.
- Corrected after a review of the NTSB narrative, which states these values explicitly: damage. The narrative states "the aircraft was substantially damaged" in the forced landing onto rough and uneven terrain, not destroyed.
