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, while establishing the second boundary along the eastern edge of a field where he was conducting an aerial application, the airplane struck power lines. Following the collision with the power lines, the airplane turned to the left and impacted the ground in a flat attitude, which resulted in structural damage to all four wings and fuselage. The pilot stated that there were four sets of power lines near the field; however, the upper right wing blocked his view of the power lines that the airplane struck. No preimpact mechanical malfunctions were reported that would have precluded normal operation of the airplane.
