Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new AD: 2013-20-04 Airbus: Amendment 39-17610. Docket No. FAA-2013-0543; Directorate Identifier 2012-NM-202-AD. (a) Effective Date This airworthiness directive (AD) becomes effective December 5, 2013. (b) Affected ADs None. (c) Applicability This AD applies to the Airbus airplanes listed in paragraphs (c)(1), (c)(2), (c)(3), and (c)(4) of this AD, certificated in any category, all manufacturer serial numbers. (1) Model A318-111, -112, -121, and -122 airplanes. (2) Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes. (3) Model A320-111, -211, -212, -214, -231, -232, and -233 airplanes. (4) Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. (d) Subject Air Transport Association (ATA) of America Code 57, Wings. (e) Reason This AD was prompted by a determination that certain special washers used in retraction jack anchorage fitting bearing installation in the main landing gear (MLG) were incorrectly manufactured. We are issuing this AD to detect and correct installation of incorrectly manufactured special washers, which could lead to a local stress concentration resulting in possible reduction of the fatigue life of the jack fitting, and consequent reduction of the structural integrity of the affected MLG. (f) Compliance You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. (g) Detailed Inspection Within 21,300 flight cycles after August 1, 2006, or within 30 days after the effective date of this AD, whichever occurs later: Do a detailed inspection of the left-hand (LH) and right-hand (RH) bearing assemblies of the [[Page 65175]] MLG retraction jack anchorage fitting for correct installation, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-57-1169, Revision 01, dated September 18, 2012, except as specified in paragraphs (i)(1) and (i)(2) of this AD. Note 1 to paragraph (g) of this AD: The affected special washers having part number (P/N) D5725260120000 and P/N D5725664320000 were manufactured between October 2006 and January 2010. (h) Related Investigative and Corrective Actions If any special washer is found incorrectly seated during the inspection specified in paragraph (g) of this AD: Before further flight, do all applicable related investigative and corrective actions, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-57-1169, Revision 01, dated September 18, 2012, except as specified in paragraph (i)(3) of this AD. (i) Exceptions to Inspections and Service Information (1) Airplanes on which Airbus Modification 39730 or Airbus Modification 150311 has been embodied in production, or on which Airbus Service Bulletin A320-57-1157 has been embodied in service, do not have to be inspected as required by paragraph (g) of this AD, unless a special washer having P/N D5725260120000 or P/N D5725664320000 has been installed since the airplane's first flight, or since modification as specified in Airbus Service Bulletin A320- 57-1157, as applicable. A review of airplane maintenance records is acceptable to make this determination if the part numbers of the special washers and modification status can be conclusively determined from that review. (2) Bearing assemblies for the MLG retraction jack anchorage fitting on which no special washer replacement has been accomplished after August 1, 2006; and bearing assemblies for the MLG retraction jack anchorage fitting on which a special washer replacement has been accomplished as specified in Task 57-26-13-400-001-A, Installation of the Bearing Assembly of the Forward Pintle Pin; Task 57-26-13-400-002-A, Installation of the Bearing Assembly of the MLG Actuator Attachment; and Task 57-26-13-400-004-A Installation of the Bearing Seals of the MLG Actuator Bearing Assembly; of Subject 57- 26-13, Attachment--Main Landing Gear, of Chapter 57, Wings, of the Airbus A318/A319/A320/A321 Aircraft Maintenance Manual (AMM), Revision 50, dated November 1, 2012; do not have to be inspected as required by paragraph (g) of this AD. A review of airplane maintenance records is acceptable to make this determination if the status can be conclusively determined from that review. (3) Where Airbus Service Bulletin A320-57-1169, Revision 01, dated September 18, 2012, specifies to contact Airbus and apply corrective action defined by Airbus: Before further flight, repairthe jack anchorage fitting using a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (EASA) (or its delegated agent). (j) Parts Installation Limitations As of the effective date of this AD, no person may install, on any airplane, a special washer having P/N D5725260120000 or P/N D5725664320000, unless it is installed in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-57-1169, Revision 01, dated September 18, 2012; or in accordance with the instructions specified in the tasks identified in paragraphs (j)(1), (j)(2), and (j)(3) of this AD.
