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 reported that it was his first flight as pilot-in-command of the tundra tire- and tailwheel-equipped airplane. While on the fourth three-point landing to the concrete runway, after the tailwheel touched down, the airplane veered left. He corrected with right rudder and attempted to return to the runway centerline and then applied left rudder, but the airplane continued to veer right. Subsequently, the airplane ground looped to the right, and the left wing struck the ground. The airplane sustained substantial damage to the left wing and fuselage. The owner of the airplane, who was seated in the rear seat, reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
