- Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
- Part 91: General Aviation

- Landing
- Defining eventThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
- Landing area undershoot
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative
The pilot was flying a standard traffic pattern to approach an ice runway on a frozen lake. The pilot described that she flew the final approach lower and slower than usual due to the known lack of braking action on the ice. The pilot stated that, based on an online video viewed the night before, she used an icy snowbank as the aiming point for landing. During the approach, the airplane was too low and slow, and the airplane’s nose and right main landing gear contacted the snowbank. The impact resulted in the nose pitching downward and the propeller striking the ice. The airplane then pivoted on the ice and came to rest with the tail positioned in the snowbank on the right side of the displaced threshold, just short of the runway. The airplane’s right wing was substantially damaged during the accident sequence. The pilot reported that there were no preimpact mechanical malfunctions or failures of the airplane that would have precluded normal operation.
Probable cause
The pilot’s failure to maintain an appropriate glide path during the landing approach, which resulted in in the airplane contacting a snowbank short of the runway.

- 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, cause areas. 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.
