Quick Launch

NTSB Identification: GAA15CA125
14 CFR Part 91: General Aviation
Accident occurred Saturday, June 06, 2015 in Waterloo, IA

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

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.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
  • 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.
