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 uncertificated pilot was landing a tailwheel-equipped airplane, with one passenger at a remote, rough and uneven off-airport site, at the completion of a Title 14, CFR Part 91, business flight. Witnesses noted that during the landing roll the airplane's right main wheel struck a log, and the right main landing gear collapsed. The right wing and right horizontal stabilizer struck the ground. The airplane sustained substantial damage to the right wing, right wing lift struts, empennage, and fuselage. Due to the remote location the airplane has not been examined by the NTSB.
NTSB Probable Cause
The uncertificated pilot's selection of an unsuitable landing site, resulting in a main landing gear collapse during the landing roll.
