NTSB narrative
The flight instructor and his student were flying in the mountains when a snow storm was encountered. The instructor decided to make a precautionary landing because flight conditions were deteriorating to IMC. While landing on the icy road, the airplane slid off into a ditch.
Probable cause
The snow shower, and the lack of suitable terrain for the precautionary landing.

- 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.
