NTSB narrative
The pilot reported that he was spraying a corn field and had descended back toward the field to make his next application pass. During the pass, he underestimated the height of the corn and the airplane settled more than expected. The main landing gear struck the corn, the airplane veered to the left, and the airplane impacted the ground. The engine separated and the airplane continued to spin to the left before it came to rest upright. The airplane sustained substantial damage to both wings and the empennage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause
The pilot’s failure to maintain adequate clearance from crops during an agricultural 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, cause areas. 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.
