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 was conducting agricultural application when he noticed the oil pressure light flickering just before making the 180o turn for his next run, and he turned toward a cornfield and made a precautionary landing. The pilot reported that the landing was soft, but the spray boom broke during landing. Two witnesses reported that the helicopter was maneuvering at low altitude and struck a wire before landing in the cornfield. They both reported that the pilot got out and examined the helicopter, got back in, took off, and departed the area. Photographs taken by a Federal Aviation Administration inspector showed that the helicopter sustained substantial damage to the main rotor blades. The pilot reported that he did not feel the impact of the rotor blades with the wire.
NTSB Probable Cause
The pilot’s failure to see and avoid a wire during an aerial application flight, resulting in a collision with the wire.
