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.

ERA10CA076
The student pilot was receiving instruction in a tailwheel-equipped biplane from a certified flight instructor (CFI). During the second landing, the student pilot landed the airplane on the runway fast and bounced; the airplane started to veer left. The student pilot corrected with right rudder application. The CFI applied full left rudder when the airplane veered to the right again, which had no effect on the airplane’s direction of travel; the student pilot then applied right brake during the CFI’s correction. The airplane continued right until it ground-looped. The biplane incurred substantial damage to both upper wings and the left lower wing. The flight crew reported no mechanical deficiencies prior to the accident.
NTSB Probable Cause
The certified flight instructor’s delayed response to the student pilot's loss of directional control while landing, which resulted in a ground-loop. Contributing to the accident was the student pilot's loss of directional control.
