[correction 12 January 2016]

Issued: 24 June 2015

Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with Regulation

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 [Regulation (EU) 1321/2014 Annex I,

Part M.A.303] or agreed with the Authority of the State of Registry [Regulation (EC) 216/2008, Article 14(4) exemption].

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) 

A35L007-14, 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 2014-0277 to require identification and replacement of the affected oxygen 

generators.

Since EASA AD 2014-0277 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 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superseded, expands the scope of the AD to include chemical oxygen generators manufactured 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 correct 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 Aerospace 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.

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, 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 with 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 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.

(4) From the effective date of this AD, it is allowed to install on any aeroplane an oxygen 

generator, provided it is determined, prior to installation, that the oxygen generator is a 

serviceable unit (see Note).
