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.

CEN10CA289
The pilot reported that she was practicing touch-and-go landings when the accident occurred. During her first touch-and-go, the airplane bounced after a hard landing. She attempted to correct for the bounced landing, but the airplane’s nose landing gear impacted the runway before the main landing gear. The airplane stabilized onto all three landing gear and she proceeded with the next takeoff. No anomalies were experienced with the two subsequent landings. A postflight inspection of the airframe revealed substantial damage to the engine firewall and fuselage floor structure. The pilot reported that there were no preimpact mechanical malfunctions or failures that would have precluded normal operation of the airplane.
