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 stated that the purpose of the agricultural flight was to spray a swath of field bordered by power lines. After making a pass, the pilot's attention was focused on a pole and he struck nearby power lines, which wrapped around the propeller. The pilot noticed a sudden loss in power and thought he could make it back to the airport. The engine then lost total power and the pilot initiated a forced landing in a field, resulting in a hard landing. The engine detached from the airplane and both wings and the fuselage sustained substantial damage. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.

After making a pass, the pilot's attention was focused on a pole and he struck nearby power lines, which wrapped around the propeller. The pilot noticed a sudden loss in power and thought he could make it back to the airport. The power loss increased and the pilot initiated a forced landing into a field, resulting in a hard landing. The engine detached from the airplane and both wings and fuselage sustained substantial structural damage. The pilot reported no mechanical failures or malfunctions that would have precluded normal flight.
