Airworthiness Directive · Amendment 39-12521 · Airbus Model A319, A320, and A321 Series Airplanes
Airbus Model A319, A320, and A321 Series Airplanes
Model A319, A320, and A321 series airplanes, certificated in any category, on which Airbus Modification 28909 was not accomplished during production.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A320 series airplanes, that currently requires modification of the autopilot mode engagement/ disengagement lever of the rudder artificial feel unit. This amendment requires a different modification of the lever. This amendment also revises the applicability to include Airbus Model A319 and A321 series airplanes, as well as all Model A320 series airplanes. 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 reduced controllability of the airplane due to the failure of the rudder artificial feel unit to disengage properly from autopilot mode during approach and landing.
