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.

The pilot indicated that the purpose of the flight was to finish the post annual flight check and to check the autorotational rpm during a simulated engine out condition. The pilot was flying in the left seat and there was an observer in the right seat. He entered a 180-degree autorotation and at 70 feet above ground level, began a gradual flare. During the flare, the helicopter contacted the asphalt surface of the taxiway. The helicopter hopped and then came to a stop. The pilot initiated another pattern and power recovery autorotation. He then hover taxied to the maintenance hangar ramp area and performed a normal shutdown. Post flight inspection revealed a wrinkle in the tail boom.
NTSB Probable Cause
The pilot misjudged the flare which resulted in a hard landing.
