Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Model 737-100, -200, -300, -400, and -500 series airplanes, and Model 747, 757, 767, and 777 series airplanes. This proposal would require replacing the rudder pedal pushrod fasteners for both the captain's and first officer's pedal assemblies with new, improved fasteners. This action is necessary to prevent loss of rudder control due to improperly torqued fasteners that connect the pushrod to the rudder pedal assembly, which could result in loss of controllability of the airplane. This action is intended to address the identified unsafe condition.
