## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300 B2 and B4 series airplanes; Model A300 B4-600, B4-600R, and F4-600R (collectively called A300-600) series airplanes; and Model A310 series airplanes. This AD requires various modifications and repetitive inspections of the throttle control system, and follow-on actions if necessary. This action is necessary to prevent hard points in the throttle control system that could lead to jamming of the throttle control cable. Such jamming could result in an asymmetric thrust condition and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
