## EASA AIRWORTHINESS DIRECTIVE

AD No.: 2011-0077

Date: 05 May 2011

Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with Regulation (EC) No 216/2008 on behalf of the European Community, its Member States and of the European third countries that participate in th e activities of EASA under Article 66 of that Regulation.
This AD is issued in accordance with EC 1702/2003, Part 21A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301, the continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may opera te an aircraft to which an AD applies, except in accordance with the requirements of that AD unless otherwise specified by the Age ncy [EC 2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exemptio n]. 

### Type Approval Holder’s Name :
AIRBUS Type/Model designation(s) : A319, A320 and A321 aeroplanes

TCDS Number : EASA.A.064

Foreign AD : Not applicable

Supersedure : This AD supersedes EASA AD 2006-0 184 dated 03 July 2006.



### ATA 25 Equipment / Furnishings – Cargo Loading System Fixed YZ Latches Attachment Points – Modification

Manufacturer(s): Airbus (formerly Airbus Industrie)

Applicability: Airbus A319-111, A319-112 , A319-113, A319-114, A319-115, A319-131, A319-132, A319-133, A320-111, A320 -211, A320-212, A320-214, A320-215, A320-216, A320-231, A320-232, A320 -233, A321-111, A321-112, A321-131, A321-211, A321-212, A321-213, A321-231 and A321-232 aeroplanes, all manufacturer serial numbers (MSN).
Reason: Investigation has revealed that the installed Tie Down Points of YZ latches on the Cargo Loading System (CLS) of Ai rbus A319, A320 and A321 aeroplanes do not withstand the maximum loads in accordance with the certification requirements (CS 25.787 “Stowage compartments”). In case of failure of Tie Down Points, unrestrained cargo parts could cause damage in the Forward (FWD) and AFT lower deck cargo holds (e.g. air conditioning, fire protection system, hydr aulic system, electrical wiring, etc.), and therefore could have an impact on the safety of the flight. EASA AD 2006-0184 was issued to require t he modification of the attachment points of fixed YZ latches of the CL S in both FWD and AFT lower deck cargo holds, as applicable to aeroplane configuration, in accordance with Airbus SB A320-25-1294 Revision 01. It has recently been identified that for some aeroplanes, Airbus SB A320-25- 1294 Revision 01 has been applied only on one of the lower deck cargo holds (FWD or AFT) while both cargo compartments were concerned by the modification, and that some aeroplanes could have installed the affected YZ through the instructions of the Cargo Conversion Manual.EASA AD No : 2011-0077

EASA Form 110 Page 2/3 For the reasons described above, th is AD, which supersedes EASA AD 2006- 0184, requires modification of the attachm ent points of fixed YZ latches of the CLS lower deck cargo holds on those aeroplanes on which one or both lower deck cargo holds have not been modified. This AD also prohibits installation of th e affected YZ latches, identified by Part Number (P/N) in Table 1 of Appendix 1 of this AD, on any aeroplane as replacement parts, unless all the attachment points of the YZ latch have been modified.

Effective Date: 19 May 2011

Required Action(s) and Compliance Time(s): Required as indicated, unless accomplished previously : (1) Within 20 months after the effective date of this AD, modify the attachment points of fixed YZ latche s of the CLS, having a P/N listed in Table 1 of Appendix 1 of this AD, in both FWD and AFT lower deck cargo holds by adding spacer assemblies with P/N D2557232700000, in accordance with the instructions of Airbus SB A320-25-1294 Revision 06. (2) Modification of an aeroplane, prior to the effective date of this AD, in accordance with the instructions of Airbus SB A320-25-1294 at original issue, or at Revision 01, Revision 02, Revision 03, Revision 04, or Revision 05, and in accordance with the instructions referenced as “additional work” (see Note below) in Airbus SB A320-25-1294 at Revision 06, as applicable to aeroplane configuration, is considered an acceptable method of compliance with the requirements of paragraph (1) of this AD for that aeroplane.
Note : For certain aeroplanes, identified by MSN in Airbus SB A320-25-1294 Revision 06, additional work has been introduced to ensure accomplishment of the modifications as required by the paragraph (1) of this AD for both AFT and FWD lower deck cargo holds. (3) Aeroplanes on which both Airbus modification (mod) 32244 and mod 32245 have been embodied in production, or both Airbus mod 32316 and mod 32317 have been embodied in production, and on which no YZ latch replacements have been made since first flight, are not affected by the modification requirements of this AD. (4) From the effective date of this AD, do not install on the CLS of an aeroplane any YZ latch with a P/N listed in Table 1 of Appendix 1 of this AD, unless all the attachment points of that latch have been modified as required by this AD.
