NTSB narrative
During takeoff for an aerial spray flight, the pilot noticed a side panel come loose on the right side of the airplane. When the airplane became difficult to control, the pilot elected to make a forced landing into a flooded rice field, which damaged both wings and fuselage.
Examination revealed the fasteners for the side panel and airframe had significant wear, which resulted in the panel coming loose during takeoff. Inadequate maintenance allowed the airworthiness hazard to exist during takeoff.
Probable cause
Inadequate maintenance of panel fasteners, which led to a side panel coming loose during takeoff and the pilot having to make a subsequent forced landing to a flooded rice field when the airplane became difficult to control.

- 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.
