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 was making a landing on a dirt landing area that also doubled as the main road in the center of the remote mountain town. He intentionally landed a little long in order to miss the substantial puddle of water near the approach end of the landing area. He began applying brakes while the airplane was going about 20 miles per hour, but his brake application was of sufficient force to result in the airplane nosing over onto its back. The sequence of events resulted in substantial damage to the vertical stabilizer and one wing lift strut. The pilot said that there was nothing wrong with the braking system, and that he should have either delayed his braking or applied the brakes with "more finesse."
