NTSB narrative
THE ACFT GROUNDLOOPED IN RUTS DURING A FORCED LANDING AFTER THE ENGINE QUIT. A GROUND FIRE DESTROYED THE ACFT. THE ACFT HAD APPROACHED THE FIELD TO BE SPRAYED AND A WITNESS ON THE GROUND SAID THE ENGINE SOUNDED LIKE IT WAS BEING THROTTLED BACK. WHEN THE PILOT TRIED TO ADD POWER THE ENGINE DID NOT RESPOND AND SHORTLY AFTERWARDS IT FAILED COMPLETELY. THE PILOT DUMPED THE SPRAY LOAD, TURNED AND LANDED IN A RICE FIELD. THE ACFT HIT RUTS AND GROUNDLOOPED. A POSTCRASH FIRE DESTROYED THE ACFT. THE POSTCRASH INVESTIGATION REVEALED A MALFUNCTION IN THE IMPELLER AND SHAFT ASSEMBLY ALLOWING THE IMPELLER TO DRAG AGAINST ITS HOUSING. AN A&P MECHANIC SAID THIS FAILED THE ENGINE.

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.
