# EASA AIRWORTHINESS DIRECTIVE

AD No.: 2011-0167

Date: 06 September 2011

Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with Regulation (EC) No 216/2008 on behalf of the Europe an 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 en sured by accomplishing any applicable ADs. Conseque ntly, no person may operate an aircraft to which an AD applies, except in accordance with the requirements of that AD, unless othe rwise specified by the Agency [EC 2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/200 8, Article 14(4) exemption].



### Type Approval Holder’s Name :

AIRBUS Type/Model designation(s) :

A318, A319, A320 and A321 aeroplanes

TCDS Number : EASA.A.064

Foreign AD : Not applicable

Supersedure : None



### ATA 35 Oxygen – Chemical Emergency Oxygen Containers –

Identification / Modification

Manufacturer(s): Airbus (formerly Airbus Industrie)

Applicability: Airbus A318-111, A318-112, 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: During production of passenger oxygen conta iners, the manufacturer B/E Aerospace detected some silicon particles inside th e oxygen generator manifolds. Investigation revealed that those partic les (chips) had chafed from the mask hoses during installation onto the generat or outlets. It was discovered that a defective mask hose installation device had caused the chafing.

This condition, if not detected and corrected, coul d reduce or block the oxygen supply, possibly resulting in injury to passengers when oxygen supply is needed.
For the reasons described above, this AD requires t he identification and modification of the affected oxygen container assem blies. This AD also prohibits the installation of the affected containe rs on any aeroplane as replacement parts.

Effective Date: 20 September 2011EASA AD No. 2011-0167

EASA Form 110 Page 2/4 

### Required Action(s) and Compliance Time(s): Required as indicated, unless accomplished previous ly:
(1) Before the accumulation of 4 500 flight cycles, or 6 000 flight hours, or 20 months, whichever occurs first after the effective date of this AD, identify the Part Number (P/N) and serial number (s/n) of ea ch passenger oxygen container installed on the aeroplane. A review of a eroplane delivery- or maintenance records is acceptable to accomplish theidentification 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 required by para graph (1) of this AD, are listed in Appendix 1 (P/N) and Tabl e 1 (s/n) of this AD, accomplish the following actions concurrently, with in the compliance time as specified in paragraph (1) of this AD, in accord ance with the instructions of Airbus Service Bulletin (SB) A320-3 5A1047:
(2.1) Replace the oxygen generator manifold of the affected oxygen container with a serviceable manifold, and
(2.2) Perform an operational check of the manual ma sk release.

(3) Oxygen containers Type I that have been modifie d in accordance with the instructions of B/E Aerospace SB 1XCXX-0100-35-005, and oxygen containers Type II that have been modified in accordance with the instructions of B/E Aerospace SB 22CXX-0100-35-003, are compliant with the requirements of the paragraph (2) of this AD.
(4) Aeroplanes on which Airbus modification 150703or Airbus modification 150704 have notbeen embodied in production do not have to comply with the requirements of paragraph (2) of this AD, unless an oxygen container has been replaced since the entry into se rvice of the aeroplane.
(5) Aeroplanes on which Airbus modification 150703 or Airbus modification 150704 has been embodied in production and which are not listed by Model and MSN in Airbus SB A320-35A1047, do not hav e to comply with the requirements of paragraphs (1) and (2) of this AD, unless an oxygen container has been replaced since the entry into se rvice of the aeroplane.
(6) A319 aeroplanes that are equipped with a Gaseo us Oxygen System for Passengers, installed in production with Airbus mod ification 33125, do not have the affected passenger oxygen containers i nstalled. Unless these aeroplanes have been modified in-service (no approved Airbus modification exists), the requirements of paragraph s (1) and (2) of this AD do not apply to these aeroplanes.
(7) From the effective date of this AD, do not inst all on any aeroplane an oxygen container with a P/N listed in Appendix 1 ofthis AD and a s/n listed in Table 1 of this AD, unless the container has been modified in accordance with the instructions of Airbus SB A320- 35A1047, or B/E Aerospace SB 1XCXX-0100-35-005, or B/E Aerospace SB22CXX-0100- 35-003, as applicable.EASA AD No. 2011-0167
