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 was conducting an aerial application flight at the time of the accident. Before spraying, he circled the field and noted high tension power lines. He completed 3 spray runs without incident, passing under the power lines on 2 of those passes. However, on the 4th pass, the pilot "did not maintain a low enough altitude" and the vertical stabilizer struck the lines. The upper portion of the vertical stabilizer and the entire rudder separated from the airframe. He was able to maintain control with a "total loss of rudder control" and executed a forced landing to a harvested wheat field.
NTSB Probable Cause
The pilot's failure to maintain clearance while attempting to fly under power lines during an aerial application pass.
