EASA AIRWORTHINESS DIRECTIVE

AD No.: 2015-0117

[Correction: 07 August 2015]

Date: 24 June 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 operate 

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) exemption].

Design 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: This AD supersedes EASA AD 2014-0275R1 dated 19 January 2015.

ATA 35 Oxygen – Chemical Oxygen Generators – Replacement

Manufacturer(s): Airbus (formerly Airbus Industrie)

Applicability: Airbus A318-111, A318-112, A318-121, A318-122, A319-111, A319-112,

A319-113, A319-114, A319-115, A319-131, A319-132, A319-133, 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 aeroplane models, all manufacturer serial numbers, except 

those that have embodied Airbus modification 33125 (gaseous system for all 

oxygen 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 reported 

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 Alert 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.

Since EASA AD 2014-0275R1 was 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 the EASA 

AD 2014-0275R1, 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 is re-published to correct a template error, removing the word 

‘Proposed’ and replacing the acronym ‘PAD’ with ‘AD’.

Effective Date: 08 July 2015

Required Action(s) 

and Compliance

Time(s):

Required as indicated, unless accomplished previously:

Partial restatement of the requirements of EASA AD 2014-0275R1:

(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 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 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 instructions for reporting the results of the activation 

(including no findings) of removed units.

Table 1 – Replacement of pre-2002 Oxygen Generators

P/N (type) Compliance Time

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 manufacturing date 2009 or later,

before exceeding 10 years since date of manufacture of the oxygen 

generator, remove from service each oxygen generator manufactured by 

B/E Aerospace and having a P/N 117042-XX, and replace it with a 

serviceable unit (see Note) 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).

Note: For the purpose of this AD, a serviceable unit 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.
