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 performing agricultural spraying operations in the helicopter when the accident occurred. He stated that he was making a final "trim" pass along the northern boundary of the field and heading west into the afternoon sun. He said that as he finished his pass, he looked down at the spray boom to insure that the nozzles were shut off and when he looked back up he saw the wires that crossed his path as they contacted the helicopter. The helicopter became uncontrollable and impacted a field in a nose-low attitude. The pilot reported no preimpact difficulties with the helicopter.
