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.

CEN23LA404
During an evaluation flight with a company pilot, the instructor pilot reported that he failed to re-apply engine power prior to the completion of a practice autorotation with a power recovery. During the maneuver, the instructor’s attention was diverted from reapplying engine power by an airplane holding short of the runway near their planned touchdown point. The helicopter subsequently landed hard on the runway, which resulted in substantial damage to the tail boom. The instructor reported that there were no preaccident mechanical malfunctions of failures with the helicopter that would have precluded normal operation.
NTSB Probable Cause
The instructor’s failure to re-apply engine power during a power recovery after a practice autorotation which resulted in a hard landing.
