## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330 and A340 series airplanes, that requires repetitive inspections to check for backlash of the spherical bearing of the active aileron servo-controls, and follow-on corrective actions, if necessary. This amendment also provides optional terminating action for the repetitive inspections. This action is necessary to detect and correct excess backlash of the spherical bearing of the active aileron servo-controls, which could result in failure of the active aileron servo-controls and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
