NTSB narrative
The agricultural airplane was destroyed after it struck power lines and impacted terrain in an open field. The pilot stated that as he completed his last spray run on a rice field, he departed the area to the south, gained altitude, and impacted the power lines running perpendicular across the field. No mechanical problems with the airplane were reported prior to the accident.
Probable cause
The pilot's failure to maintain sufficient clearance between the airplane and the power lines. A factor was the power lines.

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, 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.
