Aircraft Accident/Incident Report

Abilene, Texas 79601
Thursday, March 20, 1997 17:35 CST

NTSB Narrative Summary Released at Completion of Accident

During the takeoff roll, the bench style front seat fell backward, and neither the flight instructor nor the student pilot could reach the controls. The tailwheel equipped airplane ground looped to the left at full throttle, and the right wing tip and right horizontal stabilizer struck the ground. An FAA inspector examined the airplane and reported that the seat adjustment pin came out of the locking hole allowing the seat to slide back to the point where it became uncaptured and rolled over. The flight instructor stated that a 'better seat latch or a positive seat retainer' could have prevented the accident.

NTSB Probable Cause Narrative

The unlatching of the front bench seat for an undetermined reason.
