Airworthiness Directive · Amendment 39-12873 · Airbus Model A320 and A321 Series Airplanes
Airbus Model A320 and A321 Series Airplanes
Model A320 and A321 series airplanes, certificated in any category; having elevator part and serial numbers listed in Airbus Service Bulletin A320-55-1024, dated January 13, 1999; excluding those modified per Airbus Modification 23558.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A320 and A321 series airplanes, that requires an inspection to detect trapped water in the elevator sandwich structure, reprotection of the elevator, and corrective actions if necessary. This action is necessary to prevent damage caused by water ingress into the elevator, which could lead to debonding of the elevator skins and degradation of the initial protection, and consequent reduced structural integrity of the airplane. This action is intended to address the identified unsafe condition.
