## Summary

This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain Airbus Model A330 and A340 series airplanes, that currently requires revising the Limitations Section of the airplane flight manual to ensure that the flightcrew is advised of the proper procedures in the event of uncommanded movement of a spoiler during flight. This action would add inspections of the function of the pressure relief valves of each spoiler servo control (SSC), and corrective action if necessary. This action also would mandate eventual modification of the SSCs, which would terminate the AFM revision in the existing AD. Uncommanded movement of a spoiler during flight 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.
