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 of the ski-equipped airplane reported that, while landing off-airport on a snow-covered field, he side-loaded the landing gear on the left side against a large "tussock" hidden by the snow. The left landing gear folded under the airplane, which caused the left wingtip to drop into the snow and impact a snow-covered tussock. The airplane sustained substantial damage to the left wing. The pilot reported that there were no preimpact mechanical failures or malfunctions with the airplane that would have precluded normal operation.
