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 of a tailwheel-equipped bi-plane reported that he was performing a short field landing on a rough grass runway. The pilot further reported that he applied the brakes immediately after touchdown, and then felt the main landing gear "grab" and the tail begin to rise. Subsequently, the bi-plane nosed over on the runway. The pilot reported that he "should not have applied the brakes so soon" after touchdown. The vertical stabilizer sustained substantial damage. The pilot did not report any mechanical malfunctions or failures with the bi-plane that would have precluded normal operation.
