Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

The pilot reported that, after departing from a snow-covered glacier in a wheel/ski-equipped airplane, he retracted the skis in preparation for landing on a paved runway. During the retraction, the right wheel/ski pivoted up, striking the airplane's right wing lift strut, which sustained substantial damage. Postaccident examination revealed that the ski's right rear clevis pin had broken, which allowed the ski to pivot upward. Other than the broken clevis pin, there were no preaccident mechanical problems with the airplane.
NTSB Probable Cause
A broken wheel/ski clevis pin, which allowed the ski to pivot upward and strike the right wing lift strut.
Full Narrative
The pilot reported that after departing from a snow-covered glacier in a tailwheel and wheel/ski-equipped airplane, he retracted the skis in preparation for landing on a paved runway. During the retraction, the right wheel/ski pivoted up, striking the airplane's right wing lift strut. Inspection revealed that the ski's right rear clevis pin had broken, which allowed the ski to pivot upwards. The right wing lift strut sustained substantial damage, which required replacement. Other than the broken clevis pin, the pilot indicated there were no preaccident mechanical problems with the airplane.
