NTSB narrative
The pilot stated that he had encountered low-level turbulence during his previous agricultural application flights. During the accident flight, he noted continued turbulence and observed powerline obstructions around the field. The pilot then descended the airplane to the field beyond the power lines and leveled out about 3 to 5 feet above the corn. He reported that the airplane experienced some "sink" and that he applied back stick pressure to remain "level." However, the airplane continued to descend, contacted the corn, pitched nose down, and came to rest near the cornfield. The propeller and engine exhibited signs of power production at the time of the accident and postaccident examination revealed no anomalies that would have prevented normal operation before the accident.
The pilot stated that he was sick the weekend before the accident and should have stayed in bed. Additionally, he commented that he had been relocating to a new house where he worked long hours there. The weather at the time had a higher than standard density altitude. However, there was insufficient supporting data to determine the extent to which these issues might have played a part in the pilot's and the airplane's reduced performance during the accident flight.
Probable cause
The pilot's failure to maintain clearance from the corn during an aerial application flight.

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.
