## Abstract

This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A330 and A340-200 and -300 series airplanes, that currently requires revising the Limitations Section of the airplane flight manual (AFM) to ensure that the flightcrew is advised of the proper procedures in the event of uncommanded movement of a spoiler during flight. This amendment adds inspections of the function of the pressure relief valves of each spoiler servo control (SSC), and corrective action if necessary. This new AD also mandates eventual modification of the SSCs, which terminates the AFM revision in the existing AD. The actions specified by this AD are intended to prevent uncommanded movement of a spoiler during flight, which could result in reduced controllability of the airplane and consequent significant increased fuel consumption during flight, which could necessitate an in-flight turn-back or diversion to an unscheduled airport destination. This action is intended to address the identified unsafe condition.
