Airworthiness Directives; Airbus Model A330-301, and Model A340- 211, -212, -311, and -312 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330-301, and Model A340-211, -212, -311, and -312 series airplanes, that requires repetitive detailed visual inspections of the fuselage belly fairing support structure to detect cracks; and corrective action, if necessary. This amendment also provides an optional terminating action for the repetitive inspections. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to detect and correct fatigue cracking of the fuselage belly fairing support structure, which could result in reduced structural integrity of the fuselage belly fairing support structure.
