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 of the helicopter stated that he made two passes over the field to check for obstructions prior to beginning the aerial application flight, and remembered observing only one guy wire. While making a final application to the edges of the field, the pilot flew around the previously-observed guy wire, but the helicopter's skid contacted a second wire that he had not seen. The helicopter impacted the ground on its side, resulting in substantial damage. The pilot stated there were no mechanical malfunctions or anomalies of the helicopter that would have precluded normal operation.
NTSB Probable Cause
The pilot's failure to see and avoid a guy wire, which resulted in contact with the wire and subsequent collision with terrain.
