## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 737-600, -700, -700C, and -800 series airplanes. This action requires measurement of clearance between a certain retention bracket for the elevator power control unit (PCU) and a quadrant on the inboard side of the right elevator PCU, inspection for loose fasteners in certain retention bracket assemblies for the left and right elevator PCUs, and corrective action, if necessary. This action is necessary to prevent jamming of the elevator flight controls, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
