Abstract
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747-400 and -400F series airplanes. This action requires replacing the rudder feel, centering, and trim mechanism with a new or serviceable rudder feel, centering, and trim mechanism. This action is necessary to prevent degradation/loss of rudder feel and centering, which could result in increased pilot workload and could lead to loss of control of the airplane. This action is intended to address the identified unsafe condition.
