Airworthiness Directives; Airbus Model A319 and A320 Series Airplanes

This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A319 and A320 series airplanes, that currently requires repetitive inspections to detect cracking and delamination of the containers in which the off-wing emergency evacuation slides are stored, and corrective actions if necessary. That AD also requires eventual modifications of the slides, which terminates the requirement for repetitive inspections. This action removes the currently required repetitive inspections, and requires an additional modification of the off-wing emergency evacuation slides. The actions specified by this AD are intended to prevent the loss of the emergency evacuation slides during flight, which could result in damage to the fuselage, and to prevent incorrect inflation of the emergency evacuation slides, which could result in the emergency exits being unusable during an emergency evacuation. This action is intended to address the identified unsafe condition.
