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 reported that the cross-country flight was uneventful until the final approach portion of the landing to runway 27. She reported that the final approach was flown at the normal airspeed for the airplane. She said that the next thing she knew was that the airplane was on its nose and the left wing scraped the runway. The airplane then righted itself and skidded off the left side of the runway. The airplane incurred damage to the left wing spar. The pilot reported that the wind was from the west and that local pilots reported to her that wind from the west can create a swirl as it moves up the runway. The reported wind about the time of the accident was from 240 degrees at 11 knots, gusting to 16 knots.
