Airworthiness Directives; Airbus Model A319, A320, and A321 Series Airplanes

This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A319, A320, and A321 series airplanes, that currently requires modification of the forward and aft evacuation slide systems by replacing the Velcro restraints for the support logs with frangible link restraints. This amendment reduces the time to accomplish the modification from 3 years to 9 months. 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 the ingestion of sill support-log material into the aspirator of the evacuation slide, which could result in failure of the slide to inflate.
