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 landing on a snow-covered, off-airport landing site, he was positioning the airplane for parking. He added that the left ski broke through the ice, followed by the right ski. He reported that he had not seen the area of "soft/thin" ice before taxiing. The airplane sustained substantial damage to the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot’s selection of unsuitable terrain for landing, which led to both skis breaking through the ice while positioning the airplane after landing.
