## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A320 series airplanes, that requires an electrical continuity test of the discharge circuit for the cargo compartment fire extinguisher bottle to detect any cross-connection of the electrical wires in the cargo compartment discharge circuit, and corrective actions, if necessary. 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 incorrect distribution of fire extinguishing chemicals in the event of a fire in the cargo compartment, which, if unconfined, could spread beyond the cargo compartment.
