NTSB narrative
The pilot reported that while in the landing rollout, he saw a deer on the runway and immediately started to apply brakes; however, the deer walked into the airplane. The airplane sustained substantial damage to the left wing. The pilot stated that there were no preaccident failures or malfunctions with the airplane that would have precluded normal operation.
Probable cause
The on-ground collision with a deer on the runway during the landing roll.

- 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.
