NTSB narrative
After touching down, the pilot noticed that the airplane was not aligned with the runway and decided to abort the landing. The airplane turned left of the runway toward a cornfield, and the pilot applied power and pulled up. The airplane stalled and collided with the cornfield. The airplane sustained substantial damage to the fuselage, an engine mount, the wing struts, and the left wing spar. The pilot reported there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause
The pilot did not maintain control of the airplane during an attempted aborted landing, which resulted in an inadvertent stall.

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.
- API snapshot SHA-256: 863a90946ab965b89768f5f801eab352c9ba5cbdc411de6cf9cc6079af87c4f7; retrieved 2026-09-15T19:02:25.843Z.
