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 solo student pilot reported he was landing his tailwheel equipped airplane on a gravel airstrip towards the north at the conclusion of a Title 14, CFR Part 91 local personal flight. He said he encountered a gusting crosswind from the west, and was unable to maintain directional control during the landing roll. He went off the side of the runway, and nosed over when he applied the brakes too hard. The airplane sustained substantial damage to the right wing, vertical stabilizer, and rudder. The pilot said there were no known mechanical anomalies with the airplane prior to the accident. He also indicated that he should have received more instruction prior to the flight.
