2008-22-10 Airbus: Amendment 39-15706. Docket No. FAA-2008-0342; Directorate Identifier 2007-NM-305-AD. Effective Date (a) This airworthiness directive (AD) becomes effective December 19, 2008. Affected ADs (b) None. Applicability (c) This AD applies to Airbus Model A318, A319, A320, and A321 series airplanes, certificated in any category, all certified models; all serial numbers which have received an original French or German (as applicable) standard airworthiness certificate or original French or German (as applicable) export certificate of airworthiness prior to February 28, 2007, and have been fitted with a cargo compartment fire extinguisher bottle installed in production, or in service by an Airbus service bulletin; except airplanes on which Airbus A318/A319/A320/A321 Maintenance Review Board Report (MRBR) Task 26.23.00/03 or 26.23.00/07 has been performed. Subject (d) Air Transport Association (ATA) of America Code 26: Fire Protection.Reason (e) The mandatory continuing airworthiness information (MCAI) states: During planned maintenance visit on one A320 aircraft, a cross connection of the fire extinguishing circuit system was identified. In case of fire, this cross connection will activate (discharge) the wrong forward or aft cargo compartment fire extinguisher bottle. Failure to activate the correct bottle when required is classified as potentially catastrophic. For the reasons described above, this AD requires a one-time inspection and check of the cargo firing circuit continuity to confirm the correct connection of the dedicated wires between the discharge pushbutton switches and the relevant cargo bottle. Corrective action includes modifying the wiring connection on plug 1505VC-A. Actions and Compliance (f) Within 600 flight hours after the effective date of this AD, unless already done, perform the inspection and continuity check of the cargo firing circuit and, before next flight, do applicable corrective actions, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A320-26A1068, Revision 01, dated July 19, 2007. Actions done before the effective date of this AD in accordance with Airbus Service Bulletin A320- 26A1068, dated March 19, 2007, are considered acceptable for compliance with the requirements of this AD.
