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.

While conducting an instructional flight, the flight instructor reported that, he assumed control of the helicopter to demonstrate a left 180° autorotation, and the maneuver began normally. Part way through the maneuver, the pilot noticed that the helicopter was lower in altitude than he expected. He reported that he applied right cyclic and aft cyclic, attempting to slow the rate of descent. The helicopter landed hard and skidded to a stop. When stopped, the flight instructor and the student pilot exited the helicopter, and a postimpact fire ensued. The tail boom and fuselage sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
NTSB Probable Cause
The flight instructor’s failure to maintain control of the helicopter’s rate of descent, resulting in a hard landing.
