Aircraft Accident/Incident Report
Montgomery, Alabama 36108
Saturday, August 17, 1996 15:17 CDT
NTSB Narrative Summary Released at Completion of Accident
During takeoff, the airplane swerved abruptly to the left, collided with a runway light, then nosed over. During the postaccident examination, it was discovered that the tail steering arm would intermittently lock the rudder in a fully deflected position, with the trailing edge to the left, while allowing the tail wheel to remain aligned with the airplane centerline. Damage to the airplane, such as scuffing of the circumference of the right tire outboard side wall, and no flat spots on the left tire from a locked brake, was consistent with a fully deflected rudder at the time the tail was lifted for the takeoff. The deflected rudder would result in an abrupt swerve to the left when the tail wheel broke contact with the runway. Additionally, the airplane departed the runway about 350 feet from the point the takeoff was initiated, indicating that the swerve commenced about the point the tail would come up during takeoff roll.
NTSB Probable Cause Narrative
The locked rudder in a fully deflected position which resulted in the pilot's inability to maintain directional control.
