AD No

. : 20 14

- 027 7

Date: 19 December 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 E U 1321 /20 14 Annex I, Part M.A.301, the continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may operate an air craft to which an AD applies, except in accordance with the requirements of that AD, unless otherwise specified by the Agency [E U 1321 /20 14 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exemption].

Reason: Reports have been received indicating premature ageing o f certain passenger chemical oxygen generator s, Part Number ( P / N ) 117042

- XX

, manufactured by B/E Aerospace. Some operators reported that when they tried to activate generators
, some older units failed to activate. Given the number of failed units reported, all the generators manufactured in 1999, 2000 and 2001 must be considered u nreliable.

Th is condition

, if not corrected, could lead to failure of the generator to activate and consequently not deliver oxygen during an emergency , possibly resulting in injury to passenger s

. To address this potential unsafe condition

, Airbus issued All Operators Transmission (AOT) A35 L007

- 14, making reference to B/E Aerospace Service Information Letter (SIL) D1019

- 01 (currently at Revision 1) and B/E Aerospace Service Bulletin ( SB ) 117042

- 35

- 001

. For the reason described above, this AD require s i dentification and replace ment of the affected oxygen generators. Pending the on

- going investigation, this AD is considered to be an interim action and further AD action may follow.
