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 airplane was substantially damaged and the commercial-rated pilot, the sole occupant, was not injured. The flight was originating at the time of the accident. The pilot stated that before the accident he suspended operations due to thunderstorms in the area. With a break in the weather and calm wind conditions he elected to takeoff.
