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.

NTSB Number
CEN22LA400
The pilot reported that he was practicing autorotations when the accident occurred. After successfully completing several autorotations from the same direction, he elected to attempt one from a different direction, which put the helicopter into a tailwind. During the maneuver, when the pilot rolled off the throttle, the helicopter “lost RPM”. He attempted to add power but was too low to the ground and the helicopter landed hard and rolled onto its side. The helicopter sustained substantial damage to the fuselage and the pilot was seriously injured. The pilot reported that there were no preaccident mechanical malfunctions with the helicopter that would have precluded normal operation.
NTSB Probable Cause
The pilot’s improper decision to conduct an autorotation with a tailwind, which resulted in a hard landing and substantial damage.
