## EASA AIRWORTHINESS DIRECTIVE

AD No

. : 20 15 - 0117 [Correction: 07 August 2015]

Date: 2 4 Ju ne 2015

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 accordance with EU 1321/2014 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 [EU 1321/2014 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exempt ion].

- 231 and A321

- 232 aeroplane models, all manufacturer serial numbers , except those that have embodied Airbus modification 33125 ( gaseous system for all o xygen containers) in production

. 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 reporte d that when they tried to activate generators, 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 Al ert Operators Transmission (AOT) A35N006

- 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. Consequently, EASA issued AD 2014

- 0275 (later revised) to require identification and replacement of the affected oxygen generators.EASA AD No.: 20 15

- Internet/Intranet. Since EASA AD 2014

- 0275R1 was issu e d , and following new investigation result s, EASA have decide d to introduce a life limitation concerning all P/N 117042

- XX c hemic al o xygen g enerators , manufactured by B/E Aerospace

. For the reason describe d above, this AD retains the requirement s of the EASA AD 2014

- 0275R1, which is superseded, expands the scope of the AD to include chemical oxygen generators manufactured after 2001 , and requires the ir removal from service before exceeding 10 years since date of manufacture

. This AD is re

- published to correct a template error, remov ing the word ‘Proposed’ and replacing the acronym ‘PAD’ with ‘AD’

. Effective Date: 08 July 2015 Required A ction(s) and Compliance Time(s) : Required as indicated, unless accomplished previously: Partial r estatement of the requirements of EASA AD 2014 - 02 7 5R1: (1) Within the compliance time specified in Table 1 of this AD, as applicable, 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 A35N006

- 14. A review of aeroplane maintenance records is accepta ble to make this identification, provided those records can be relied upon for t he purpose of this requirement. (2) Within the compliance time specified in Table 1 of this AD, as applicable, remove each affected oxygen generator from service and replace it with a serviceable unit in accordance with the instructions of Airbus AOT A35N006

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

- 35

- 001 (for 15 min generators)

. B/E Aerospace SIL D1019

- 01 Revision 1 provides instructions for the activation and the disposal of a removed oxygen generator. Airbus AOT A35N006

- 14 (Appendix 1) includes inst ructions for reporting the results of the activation (including no findings) of removed units.
