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 flight instructor was demonstrating a soft field takeoff maneuver with 10° of flaps. After lift-off, the airplane “suddenly” and immediately yawed to its left. Both the angle of attack indicator and the stall warning horn provided audible alerts as the pitch attitude exceeded 10° on the primary flight display. The airplane rolled left, right, and left again before it touched down, transitioned a grass area, and came to rest upright on a taxiway. The pilots egressed the airplane unhurt and discovered substantial damage to the left wing. The flight crew reported that there were no mechanical deficiencies with the performance and handling of the airplane.
