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.

ERA23LA146
The flight instructor reported that he was demonstrating a 180° autorotation for his passenger into an open field off airport grounds. Nearing the end of the maneuver, prior to touchdown, he failed to recover engine power in a timely manner which resulted in the rapid decay of the rotor rpm at low altitude; this resulted in a hard landing that subsequently caused the main rotor blades to make contact with the tail boom and severed the tail rotor driveshaft. The helicopter sustained substantial damage to the fuselage and the main rotor blades. The pilot reported that there were no pre accident mechanical malfunctions with the helicopter that would have precluded normal operation.
NTSB Probable Cause
The pilot’s failure to maintain adequate main rotor RPM during an autorotation which resulted in a hard landing and subsequent rotor blade strike of the tail boom.
