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 flying the helicopter parallel to a 10-ft-tall fence while herding cows into a livestock pen. While maneuvering, the tail rotor struck the fence, and the helicopter spun multiple times. The helicopter ascended about 10 ft, and the pilot retarded the throttle and lowered the collective to the full-down position to minimize the rapid right spin. The helicopter impacted the ground and came to rest upright. The helicopter sustained substantial damage to the tail rotor drive system and tailboom.
