## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A319, A320, and A321 series airplanes, that requires replacing certain flight warning computers (FWCs) with improved FWCs. 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 erroneous display of decision height information to the flightcrew during final approach, which could result in an increased risk of collision with terrain.
