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 construction project landing zone, the helicopter struck a static wire that had been recently positioned above the landing area. The helicopter’s main rotor blades contacted the wire which resulted in substantial damage to the blades. The pilot was unaware of the static wire and did not observe it during the approach. The pilot reported that there were no preaccident mechanical malfunction or failures of the helicopter that would have precluded normal operation.
