                - an oxygen diaphragm replacement on the affected manifold assemblies, and

                - after replacement of the diaphragm on aircraft, a leak check of the cabin emergency oxygen system.
             This Amendment does not require additional work but is issued to reduce the applicability by reference to Airbus modification 53578.
             The original issue of this Airworthiness Directive became effective on 22 September 2004.
