NTSB narrative
During a visual approach in icing conditions, the pilot retracted the landing gear to prevent ice from building up on the gear. He reported that, as he applied power to abort the approach, he saw the runway and continued the landing. Due to fatigue and other distractions, the pilot said that he failed to re-extend the landing gear and landed the airplane gear-up. The airplane slid into a snow berm, and received substantial damage to the wings and fuselage.
Probable cause
The pilot landed without lowering the landing gear. Contributing to the accident was the pilot's self-reported fatigue.

- 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.
