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 reported that he was landing the helicopter on a remote helipad. After touchdown, he lowered the collective and the helicopter rolled backwards sustaining substantial damage to the main rotor system, fuselage, and tail boom. The pilot reported that there were no preaccident mechanical malfunctions or anomalies with the helicopter that would have precluded normal operation, and that the accident may have been prevented if he had received additional training from the company to include landing on different size helipads, and techniques to ensure the helicopter was safely on the helipad before completely lowering the collective.
