NTSB narrative
The pilot reported that she was landing the airplane at a remote area of mountainous, snow-covered terrain and that she had selected an area that was slightly uphill for landing. She felt uncomfortable with the final stages of the approach, so she chose to go around. During the go-around, she added full power and started a left turn. The airplane subsequently impacted an area of rising, snow-covered terrain, which resulted in substantial damage to the right wing and fuselage. The pilot added that she should have made another practice approach or two to verify the wind direction and local terrain conditions.
Probable cause
The pilot's selection of unsuitable terrain for landing, which necessitated a go-around, and her subsequent failure to maintain clearance from rising mountainous terrain.

- 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.
