## EASA AIRWORTHINESS DIRECTIVE

AD No

. : 20 14 - 0208

Date: 16 September 2014

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 the activities of EASA under Article 66 of that Regulation. This AD is issued in accordance with EU 748/2012, Part 21.A.3B. In accordan ce 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 Agency [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]

. 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 mask hoses during installation onto the generator outlets. It was discovered that a defective mask hose installa tion 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. It was subsequently established that Model s A318

- 121 and A318

- 122 were missing from the Applicability of the AD, and clarification was necessary regarding the affected containers

- Internet/Intranet. Consequently , EASA issued AD 2012

- 0083, retaining the requiremen ts of EASA AD 2011

- 0167, which wa s superseded, expand ed the Applicability by adding two aeroplane models, and provide d clarity by providing a list of affected passenger oxygen containers. Since that AD was issued, it was found that the affected containers have not only been marked with company name B/E Aeros pace, as was specified, but also , for a brief period , with the former company name DAe Systems

. For the reason described above, this AD retains the requirements of EASA AD 2012

- 00 83 , which is superseded, and expands the affected group of containers to include those that have the name “DAe Systems” on the identification plate. This AD also clearly separates the serial number (s/n) groups of containers into those manufactured by B/E Aerospace and those manufactured by DAe Systems , for which additional compliance time is provided

. Effective Date: 30 September 2014 Required Action(s) and Compliance Time(s): Required as indicated, unless accomplished previously: (1) Within the compliance time specified in Table 1 of this AD, as applicable, identify the Part Number (P/N) and 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.

“ DAe Systems ” on the identification plate (see Table 3 of this AD) Within 2 500 FC, or 3 750 FH, or 12 months, whichever occurs first after the effective date of this AD

(2) If a container, identified as required by paragraph (1) of this AD, has a P/N a s listed in Table 2 and has a s/n as listed in Table 3 or Table 4, as applicable, of this AD, accomplish the following actions concurrently, within the compliance time as specified in Table 1 of this AD, as applicable, in accordance with the instructions of Airbus Service Bulleti n (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 container is listed in B/E Aeros pace SB 1XCXX
