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 pilot reported that during an approach to an off-airport confined area, the skid struck the top of a power line that he did not see. Upon impact the helicopter began to nose over and spin as the pilot closed the engine throttle. The helicopter subsequently impacted the road adjacent to the intended landing point. The tail boom separated, and the main rotor system and airframe sustained substantial damage. The pilot reported that there were no preimpact mechanical failures or malfunctions that would have precluded normal operation.
