## EASA AIRWORTHINESS DIRECTIVE

AD No . : 20 12 - 0 0 8 3

Date: 1 6 May 2012 Note: This Airworthiness Directive ( AD) is issued by EASA, acting in accordance with Regulation (EC) No 216/2008 on behalf of the Eu ropean Community, its Member States and of the European third countries that participate in the 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 ope rate an aircraft to which an AD applies, except in accordance with the requirements of that AD unless otherwise specified by the Agen cy [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 ) exemption ].

### ATA 35 Oxygen – Chemical Emergency Oxygen Containers – Identification / Modification Manufacturer(s): Airbus (formerly Airbus Industrie) Applicability: Airbus A318 - 111, A318 - 112, A318 - 121, A318 - 122, A319 - 111, A319 - 112, A319 - 1 13, 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 S erial Numbers (MSN)

. Reason: During production of passenger oxygen containers, the manufacturer B/E Aerospace detected some silicon particles inside the oxygen generator manifolds. Investigation revealed that those particles (chips) had chafed from the ma sk hoses during installation onto the generator outlets. It was discovered that a defective mask hose installation device had caused the chafing. This condition, if not detected and corrected, could reduce or block the oxygen supply, possibly resulting in injury to passengers when oxygen supply is needed

. To address this potential unsafe condition, EASA issued AD 2011 - 0167 to require the identification and modification of the affected oxygen container assemblies. That AD also prohibited the installation of the affected containers on any aeroplane as replacement parts. Since that AD was issued, it was established that the Models A318 - 121 and A318 - 122 were missing from the Applicability of the AD, and clarification was necessary regarding the affected contain ers, which are only those markedE ASA AD No : 20 12 - 0 0 8 3

B/E Aerospace Systems on the equipment data plate. For the reasons described above, this AD retains the requirements of EASA AD 2011 - 0167, which is superseded, expands the Applicability by adding two aeroplane models, and p rovides clarity by providing a list of affected passenger oxygen containers. Effective Date: 3 0 M ay 2012 Required A ction(s) and Compliance Time(s): Required as indicated, unless accomplished previously: (1) B efore the accumul ation of 5 000 flight cycles, or 7 500 flight hours, or 24 months, whichever occurs first after 20 September 2011 [the effective date of EASA AD 2011 - 0167], identify the Part Number (P/N) and serial number (s/n) of each passenger oxygen container installed on the aeroplane. A review of aeroplane maintenance records is acceptable to accomplish the identification as required by this paragraph, provided those records can be relied upon for that purpose. (2) If the P/N and s/n of a container, identified as requ ired by paragraph (1) of this AD, are listed, respectively, in Table 1 (P/N) and Table 2 (s/n) of this AD, accomplish the following actions concurrently, within the compliance time as specified in paragraph (1) of this AD, in accordance with the instructio ns of Airbus Service Bulletin (SB) A320 - 35A1047: (2.1) Replace the oxygen generator manifold of the affected oxygen container with a serviceable manifold, (2.2) Perform an operational check of the manual mask release, and (2.3) Check if the P/N of the cont ainer is listed in B/E Aerospace SB 1XCXX - 0100 - 35 - 005 Revision 01, or B/E Aerospace SB 22CXX - 0100 - 35 - 003 Revision 01, and if is not listed, contact Airbus for instructions and accomplish those instructions accordingly.
