NTSB narrative

The solo private pilot was landing a wheel-equipped airplane at an off-airport, snow-covered site. During the landing roll, the airplane bounced when it encountered a small snowdrift. The pilot said that he attempted to recover but the airplane drifted to the right and nosed over when it touched down in deep snow. The airplane sustained substantial damage to the vertical stabilizer, rudder, and wing lift struts. The pilot said there were no preaccident mechanical problems with the airplane, and noted in his report to the NTSB that he should have selected a better area to land on.

Probable cause

The pilot's selection of an unsuitably rough and snow-covered landing area.

  • 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.
  • API snapshot SHA-256: c665a37bd84d9cf438159605744227d48b0afe1e71a03512cfd2eb1a8860f4e0; retrieved 2026-09-15T10:54:49.723Z.
