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 flight instructor and the student pilot, who was on the controls, were taxiing for departure when the airplane started to veer right of the taxiway centerline. To correct the veer, the student quickly applied the brakes. The instructor reported that he could not intervene quickly enough before the airplane nosed over and came to rest inverted on the taxiway. The airplane sustained substantial damage to the right wing and vertical stabilizer. The instructor reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
