## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A340 series airplanes. This action requires a rototest inspection for fatigue cracking of the vertical support beam at the upper first fastener row of the actuator attachment fitting of the center landing gear (CLG), and follow-on actions. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent fatigue cracking in the vertical support beam that supports the CLG actuator attachment fitting, which could result in reduced structural integrity of the airplane.
