## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A320 series airplanes, that requires modification of certain fastener holes on the outer frames of the fuselage, and installation of new, improved fasteners. 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 prevent fatigue cracking of certain fastener holes on the outer frames of the fuselage, which could result in reduced structural integrity of the airplane.
