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 student pilot reported that upon engine startup for a local solo flight the airplane “almost immediately pivoted to the left.” The airplane impacted a two support beams of the shade hangar it was parked under, substantially damaging the left wing. The pilot reported that the parking brake was set when the engine was started and that his feet were on the brakes. A witness reported that the airplane “started up with what sounded like an excessively high RPM.” Postaccident inspection of the throttle, toe brake, and parking brake system by a Federal Aviation Administration inspector found no anomalies that would have precluded normal operation.
