[correction 12 January 2016] I ssued : 24 June 2015
Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with Regulation (EC) 216/2008 on behalf of the European Union , 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 Regulation ( EU ) 748/2012, Part 21.A.3B. In accordance with Regulation ( EU ) 1321/2014 Annex I, Part M.A.301, the continuing airworthiness of an aircraft shall be ensured by accomplishing any applicab le ADs. Consequently, no person may operate an aircraft to which an AD applies, except in accordance with the requirements of that AD, unless otherwise specified by the Agency [ Regulation ( EU ) 1321/2014 Annex I, Part M.A.303] or agreed with the Authority o f the State of Registry [ Regulation ( EC ) 216/2008, Article 14(4) exemption]

- Internet/Intranet. An agency of the European Union Page 2 of 5 Reason: Reports have been received indicating premature ageing of certain chemical oxygen generators, Part Number (P/N) 117042

- XX (XX representing any numerical value), manufactured by B/E Aerospace. Some operators reported that when they tried to activate genera tors, some older units failed to activate. Given the number of failed units reported, all generators manufactured in 1999, 2000 and 2001 were considered unreliable.
This 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 aeroplane occupants.
To address this potential unsafe condition, Airbus issued Alert Operators Transmission (AOT) A35L007

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

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

- 35

- 001. Consequently, EASA issued AD 2014

- 0277 to require identification and replacement of the affected oxygen generators.

Since EASA AD 2014

- 0277 w as issued, and following new investigation results, EASA have decided to introduce a life limitation concerning all P/N 117042

- XX chemical oxygen generators, manufactured by B/E Aerospace.
For the reason described above, this AD retains the requirements of EASA AD 2014

- 0277, which is superseded, expands the scope of the AD to include chemical oxygen generators manufactured after 2001, and requires their removal from service before exceeding 10 years since date of manufacture.
This AD was republished to c orrect a typographical error in the applicability.
Required Action(s) and Compliance Time(s): Required as indicated, unless accomplished previously:
Partial restatement of the requirements of EASA AD 2014

- 0277: (1) Within 30 days after 24 December 2014 [the effective date of EASA AD 2014

- 0277], identify the date of manufacture (see Appendix 1 of this AD where this is located) of each oxygen generator, having a P/N as listed in Table 1 of this AD, in accordance with the instructions of Airbus AOT A35L007

- 14.
A review of aeroplane maintenance records is acceptable to make this identification, provided those records can be relied upon for the purpose of this requirement.
(2) Within the compliance time specified in Table 1 of this AD, as applicable, remove and replace each affected oxygen generator from service in accordance with the instructions of Airbus AOT A35L007

- 14 (for 15 and 22 min generators), or in accordance with the instructions of B/E Aerospace SB 117042

- 35

- 001 (for 15 min generators).
B/E Aer ospace SIL D1019

- 01 Revision 1 provides instructions for the activation and the disposal of a removed oxygen generator. Airbus AOT A35L007

- 14 (Appendix 1) includes instructions for reporting the results of the activation (including no findings) of removed units.EASA AD No.: 2015

New requirements of this AD : (3) Within the compliance time as specified in Table 2 of this AD, as applicable, and, for generators with a manufactur ing date 2009 or later, before exceeding 10 years since date of manufacture of the oxygen generator, whichever occurs later, as applicable, remove from service each oxygen generator manufactured by B/E Aerospace and having a P/N 117042

- XX, and replace it w ith a serviceable unit (see Note) in accordance with the instructions of Airbus AOT A35L007

- 14 (for 15 and 22 min generators), or the instructions of B/E Aerospace SB 117042

- 35

- 001 (for 15 min generators).
Note: For the purpose of this AD, a serviceable u nit is an oxygen generator having P/N 117042

- XX with a manufacturing date not older than 10 years, or any other approved P/N, provided that the generator has not exceeded the limit established for that generator by the manufacturer.
