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 was conducting a short-field landing demonstration on a dirt airstrip. During the landing approach, the tailwheel impacted a berm of dirt located at the approach end of the airstrip. The nose pitched down and the propeller struck the runway, followed by the main landing gear. The airplane then bounced back into the air and the pilot added engine power. The airplane skidded to the left, resulting in the right main landing gear and tailwheel separating during the impact sequence. The pilot indicated that he should have landed farther down the airstrip. He reported no preimpact mechanical anomalies with the airplane that would have precluded normal operation.
