We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions in accordance with the instructions defined in Airbus Service Bulletins A330-28-3103 and A340-28-4120, both Revision 01, both dated January 11, 2008; and A340-28-5044, dated July 17, 2007; as applicable. Actions done before the effective date of this AD in accordance with Airbus Service Bulletins A330-28-3103 and A340-28-4120, both dated July 17, 2007, are acceptable for compliance with the corresponding requirements of this AD.
(1) Within 18,000 flight hours from the effective date of this AD: Replace the refuel isolation valve(s); and re-identify the refuel/defuel coupling in accordance with the instructions defined in the applicable service bulletin.
(2) For refuel Isolation Valve and Refuel/Defuel Coupling Spare units: From the effective date of this AD, no person may install an affected refuel isolation valve unit or an affected refuel/defuel coupling unit as a replacement part on an aircraft, unless it has been modified in accordance with the instructions defined in the applicable service bulletin.
