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 the tailwheel-equipped airplane reported that he was landing on a soft turf runway following an uneventful local flight. During the landing roll, he applied "a little too much braking," and the airplane nosed over. Postaccident examination of the airplane by a Federal Aviation Administration inspector revealed that the vertical stabilizer, rudder, and fuselage were buckled. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot's failure to maintain directional control during the landing roll on a soft turf runway, which resulted in a nose-over.
