NTSB narrative

The pilot and passenger were departing a frozen lake in the ski-equipped airplane. The pilot reported he was taxiing at an excessive speed. Due to flat lighting conditions, the pilot did not see a frozen snow berm. The right landing gear ski crested the berm and then struck a second snow berm. The right main landing gear was torn from the airplane fuselage.

Probable cause

The pilot's excessive speed while taxiing. A factor in the accident was flat light conditions.

  • 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.
