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.

GAA18CA249
The chief pilot reported that, while the pilot was working on transmission power wires, the pilot maneuvered the helicopter closer to the wires to give a better position for the other crewmember. He added that the pilot heard a noise and felt a vibration from the tail section. The pilot moved away from the wires, noticed no abnormality of flight, and returned to the landing zone without further incident. Postaccident examination revealed that the helicopter sustained substantial damage to the tail rotor. The chief pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
NTSB Probable Cause
The pilot’s failure to maintain adequate clearance from transmission power wires, which resulted in a tail rotor strike.
