## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Aerospatiale Model ATR72-101, -201, -102, -202, - 211, and -212 series airplanes, that requires a one-time inspection of harness route 2P and the pitch control cable for wire chafing, corrective action, if necessary; and replacement of the clamp retaining the power supply cable loom of the green circuit hydraulic pump at frame 28 with a smaller clamp in a different orientation. This action is necessary to prevent the chafing of electrical wires, which could cause a short circuit and failure of the elevator control cable and the green system hydraulic pump, resulting in reduced controllability of the airplane and consequent injury to the crew and passengers. This action is intended to address the identified unsafe condition.
