Aircraft Accident/Incident Report
Marina, California 93933
Sunday, June 4, 2006 14:00 PDT
NTSB Narrative Summary Released at Completion of Accident
The pilot's seat slid aft during the takeoff roll and the airplane nosed over after veering off the runway surface. As the pilot powered the airplane for the takeoff roll, his seat slid aft and he was unable to reach the controls to maintain control of the airplane. It veered left off the runway and came to rest inverted. Post accident examination of the seat track showed that the seat locking pin positively engaged in all of the seat track holes. The most forward hole contained a bolt used as a forward seat stop to prevent the seat from coming off of the seat track. When the seat pin was engaged in this hole, full depth engagement was not possible. Rub marks were present on the bolt shank that was visible through the seat track hole. The pilot normally flew the airplane with the seat in its forward most position. The airplane manufacturer did not design the seat stop and there was no installation record of the bolt used as a seat stop in the airplane maintenance records. The airplane was equipped with an after-market backup seat stop to prevent the seat from slipping aft if the primary seat locking mechanism failed. Although there were no mechanical problems noted with the device, the backup stop was not secured to the seat track.
NTSB Probable Cause Narrative
the installation of the unapproved forward seat stop by unknown maintenance personnel, which did not allow for full depth engagement of the seat lock pin, resulting in the seat slipping aft during the takeoff roll and subsequent loss of directional control. A contributing factor to the accident was the pilot's failure to secure the backup seat stop.
