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.

During the landing roll on a dirt strip, the pilot felt the airplane’s tail section “bottom out”. The pilot lost rudder control, and the airplane veered off the strip into vegetation and ground looped. During the ground loop, the left wing struck the ground, which resulted in substantial damage to the left wing and aileron. A postaccident examination of the airplane found that one of the bolts which secured the tail wheel spring to the tail wheel housing assembly had fractured. The pilot did not submit the National Transportation Safety Board Pilot/Operator Aircraft Accident/Incident Report Form 6120.1.
