NTSB narrative
The pilot said that, during the landing rollout, the airplane veered to the right and exited the runway. The airplane subsequently encountered a berm and came to rest in an adjacent corn field. The airplane sustained substantial damage to the left wing and fuselage. A postaccident examination revealed that the right main landing gear wheel had separated from the airplane. The components that retained the main wheel had separated from the axle and were not recovered. Visual examination of the bolt attachment hole on the landing gear strut axle did not reveal any damage. The reason for the wheel separation could not be determined.
Probable cause
Separation of the right main wheel during landing rollout for undetermined reasons.

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.
