NTSB narrative
The aerial application airplane's right wing collided with a tree while working a pattern that was oriented in an east-west direction, causing the airplane to impact the terrain and cartwheel. The pilot reported that during insecticide application some overspray accumulated on the windscreen, leaving an oily residue that obscured his vision when his direction of flight headed into the sun.
Probable cause
The pilot's failure to maintain visual separation between his airplane and a tree while maneuvering during aerial application and the subsequent collision with the tree and the terrain. A factor in the accident was the sunglare on the airplane's windscreen.

- 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.
