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.

GAA15CA107
The rated pilot and flight instructor were practicing off airport landings in unimproved areas in the tailwheel equipped airplane. After two evaluation passes, the pilot landed. The pilot reported that during the rollout the airplane had oscillations around the lateral axis and the pilot applied the brakes. The flight instructor also applied brake pressure during the landing roll. The airplane nosed over and came to rest inverted. The airplane sustained substantial damage to right wing strut, vertical stabilizer, and rudder. The pilot reported no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. The pilot reported the accident may have been avoidable with better communication and transfer of controls with the flight instructor.
NTSB Probable Cause
The pilot's and flight instructor's improper brake application during the landing roll. Contributing to the accident was the flight instructor's failure to make a positive transfer of controls.
