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.

During an aerial application flight over a river, the pilot was spreading seed when the airplane struck and severed all four wires of an electrical transmission power line. During the forced landing, the airplane impacted tall vegetation. The fuselage, empennage, and both wings were substantially damaged. According to the pilot and photographs of the area, neither the transmission wires nor the poles were visible above the tree line adjacent to the river banks. The pilot stated that he had been warned about the transmission lines that extended over the river and should have located them before the application portion of the flight began.
