NTSB narrative
The pilot reported that he had departed from the private airstrip on two previous agricultural aerial application flights. During the next takeoff roll, the airplane veered to the left when it passed the center crown in the runway. He reported that the main wheel "caught" a deep rut at the runway edge. The airplane went off the runway and the left wing impacted a cornfield, which spun the airplane around. The landing gear, propeller, and empennage sustained substantial damage. The airport used by the pilot was a privately owned, paved airstrip used only by agricultural spray aircraft.
Probable cause
The pilot failed to maintain directional control during the takeoff roll. Contributing to the accident were the uneven runway, the runway edge, and the cornfield.

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.
