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 taxiing to the north, on the west side of the runway outside of the runway markers in preparation for takeoff. While maneuvering the airplane around a pothole, he lost sight of the windsock pole in the clutter of trees lining the airport boundary. Subsequently, the left wing struck the windsock pole, resulting in substantial damage to the wing spar. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
