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 stated that the purpose of the flight was to conduct low-level aerial operations for cattle herding. The pilot maneuvered the helicopter in an effort to keep the cattle close together and did not notice a phone line in the helicopter's flight path. The main rotor blades contacted the lines and they became entangled in the main rotor head. The helicopter descended from approximately 15 feet above ground level and impacted the terrain hard, collapsing the skids. As a result of the impact, the helicopter sustained substantial damage to both the tail and main rotor blades. The pilot reported no pre impact mechanical malfunctions or failure with the helicopter that would have precluded normal operation.
NTSB Probable Cause
The pilot's failure to maintain an adequate obstacle clearance altitude from phone wires while performing low-level operations.
