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 ground looped resulting in substantial damage to the right wing, right aileron, and fuselage. The pilot reported no mechanical malfunctions with the airplane prior to the accident. After the accident, the pilot and certificated flight instructor reported the wind was about 3 to 4 knots down the runway, with dust devils crossing the runway.
