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 accident occurred during an instructional flight while practicing landings. The flight instructor reported that he became distracted while teaching his student and forgot to ensure that the landing gear was extended before landing. He stated that the landing gear warning horn was sounding before touchdown, but he did not realize that the landing gear was not configured until it was too late. Post accident inspection revealed that several fuselage structural components were damaged during the gear-up landing. The flight instructor reported that there were no preimpact mechanical malfunctions or failures that would have precluded normal operation of the airplane.
