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 in the tailwheel-equipped airplane reported that, before landing on the narrow, gravel airstrip, the airplane encountered a wind gust from the right that "pushed me to the left a few feet." The airplane's left wing contacted brush on the left side of the airstrip, and the airplane then exited the left side of the airstrip. The airplane descended into a 2-ft-deep ditch and stopped. The airplane sustained substantial damage to the left wing spar. The pilot reported that the wind conditions were variable and gusting to 8 knots, that the skies were clear, and that the visibility exceeded 10 miles. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
