## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Airbus Model A330-301, -321, -322, -341, and - 342 series airplanes. This action requires replacement of the existing fasteners on the vertical web of stringers 13 and 20 of both wings with interference fasteners. This action is necessary to prevent fatigue cracking of the wing bottom skin and vertical webs, which could result in reduced structural integrity of the wing. This action is intended to address the identified unsafe condition.
