NTSB narrative
The pilot reported that, after landing on a gravel airstrip, during the taxi, a moose cow and calf ran onto the airstrip, moving from the pilot's right to left. She added that she veered to the left to avoid the animals and the airplane struck a tree.
The airplane sustained substantial damage to the fuselage.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Probable cause
The pilot’s abrupt maneuver to avoid a moose cow and calf during taxi, which resulted in an impact with a tree.

- 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.
