Narrative:
The airplane ground looped off the runway when the pilot's seat slid aft during landing. The pilot said that when he flared for landing he heard a "click" and then his seat slid backwards about 1 foot, restricting his ability to reach the controls. The pilot tried to adjust his seat position to regain access to the airplane's controls, but the airplane entered a left ground loop and came to rest left of the runway. A Federal Aviation Administration inspector examined and photographed the pilot's seat. He reported that the seat track locking pin was positioned outside the seat track. He observed that the side floor deck was buckled, the seat was structurally deformed, and the seat locking pin was outside the seat rail and roller, all indicative of impact related damage. The inspector stated that he could not make a reliable determination of pin position prior to the impact damage.

Probable Cause: the pilot's inadequate preflight inspection which failed to determine the security of his seat, and his failure to maintain directional control.
