Event Location
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.
Full Narrative
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.
