## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Airbus Model A300 B4-600, B4-600R, C4 605R Variant F, and F4-600R (collectively called A300-600) series airplanes; and Model A310 series airplanes. This action requires a one-time inspection for damage of the integrated drive generator electrical harness and pyramid arm, and repair if necessary. This action is necessary to prevent electrical arcing within the engine pylon, which could result in loss of the relevant alternating current (AC) bus bar, reduced structural integrity of the engine pylon, and consequent loss of control of the airplane. This action is intended to address the identified unsafe condition.
