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 aerial application pilot reported that he was setting navigational equipment while en route to a field to spray. He stated that he became fixated on the unit. He said, “at the end of the field was a levy with a road on top of it. I noticed this too late and impacted the landing gear of the aircraft at the top of the levy. The airplane continued to fly and I knew I had hit something.” Review of photographs of the airplane showed that structural tubing was torn away from the fuselage tubing and the torn structure remained attached to the separated landing gear.
