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 flight instructor reported that, during preparation for the pilot's helicopter commercial checkride, they were going to practice autorotation procedures. He added that, during the second autorotation, he saw that the rotor rpm had dropped significantly and that the pilot was pulling up on the collective. He immediately took command of the flight controls and attempted to lower the collective. Subsequently, the helicopter landed hard, bounced, yawed right, bounced again, and then came to rest on the right side of the runway. The helicopter sustained substantial damage to the tailboom. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.

Subsequently, the helicopter landed hard, bounced, yawed right, bounced again, and came to rest on the right side of the runway. The helicopter sustained substantial damage to the tailboom. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
