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 helicopter instructor was demonstrating a full down 180 degree auto rotation. He reported that everything was done normally and as he flared to slow the aircraft down, the tail skid lightly bumped the ground a couple of times. The skids eventually made contact with the ground and the helicopter slid about 20 feet to a stop. A post landing examination of the helicopter revealed that the main rotor blade had contacted the tailboom, severing the tailrotor drive shaft.
