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.

GAA15CA125
The pilot reported that during the takeoff roll, the seat slid to its full aft position. He was unable to reach the control pedals and attempted to abort the takeoff. The pilot was not able to control the airplane and it yawed left into a ground loop. The airplane sustained substantial damage to the right horizontal stabilizer, right wing, and right aileron. A postaccident examination by the NTSB Investigator-in-Charge and Textron Aviation revealed the secondary seat stop reel was not installed according to the manufacturer's guidelines. The incorrect installation prevented the primary seat adjustment mechanism from fully engaging into the holes in the seat rail.
NTSB Probable Cause
The incorrect installation of the secondary seat stop reel which resulted in the pilot's loss of control when the seat moved full aft during takeoff.
