- 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

- Maneuvering · low-altitude flying
- 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
- Loss of visual reference
- 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 operator reported that the pilot had diverted to an alternate airport due to weather. As the flight approached the alternate airport, the weather had deteriorated, and the pilot requested a Special VFR clearance. The flight continued to follow the lake shoreline and the pilot recalled circling once while waiting for the clearance.
Prior to reaching “the mouth of the river”, the pilot made the decision to divert to another alternate airport, due to the visibility getting worse as they approached the airport. As the pilot began to make an approximate 20° right hand turn over the frozen, snow-covered lake, he noticed the airplane was losing altitude and remembers increasing power and pitch, around this point he “switched to instruments”. The passenger recalled looking to his right and remarked it was like looking at a “white sheet of paper” with the sky blending with the frozen lake. Moments later, the airplane impacted the snow-covered ice while in the turn to the right.
The airplane sustained substantial damage to the wings, fuselage, and empennage. The operator reported that there were no mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Probable cause
The pilot’s decision to continue visual flight into an area of instrument meteorological conditions, which resulted in the pilot experiencing a loss of visual reference and subsequent controlled flight into 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, 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.
