EASA AIRWORTHINESS DIRECTIVE

AD No.: 2014-0277

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 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) :

A330 and A340 aeroplanes

TCDS Number : EASA.A.004 and EASA.A.015

Foreign AD : Not applicable

Supersedure: None

ATA 35 Oxygen – Passenger Chemical Oxygen Generators – Replacement

Manufacturer(s): Airbus (formerly Airbus Industrie)

Applicability: Airbus A330-201, A330-202, A330-203, A330-223, A330-223F, A330-243,

A330-243F, A330-301, A330-302, A330-303, A330-321, A330-322, A330-323, 

A330-341, A330-342 and A330-343 aeroplanes, all manufacturer serial numbers 

(MSN).

Airbus A340-211, A340-212, A340-213, A340-311, A340-312, A340-313,

A340-541, A340-542, A340-642 and A340-643 aeroplanes, all MSN.

Reason: Reports have been received indicating premature ageing of certain passenger 

chemical oxygen generators, 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 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 passengers.

To address this potential unsafe condition, Airbus issued All 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.

For the reason described above, this AD requires identification and replacement 

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.

Required Action(s) 

and Compliance

Time(s):

Required as indicated, unless accomplished previously:

(1) Within 30 days after the effective date of this AD, identify the date of 

manufacture (see Appendix 1 of this AD where this is located) of each

passenger 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 passenger oxygen generator from service 

in accordance with the instructions of Airbus AOT A35L007-14 and/or, for

15 min generators, in accordance with the instructions of B/E Aerospace SB 

117042-35-001.

B/E Aerospace SIL D1019-01 Revision 1 provides instructions for the 

activation and the disposal of a removed passenger oxygen generator.

Airbus AOT A35L007-14 (Appendix 1) includes instructions for reporting the 

results of the activation (including no findings) of removed units. The data 

gathered from those results will be analysed to determine further action(s), if 

any.

117042-03 (15 min – 3 masks) 

117042-04 (15 min – 4 masks)

117042-22 (22 min – 2 masks)

117042-23 (22 min – 3 masks)

117042-24 (22 min – 4 masks)

For units manufactured in 1999, 

before exceeding 15 years since 

date of manufacture, or within 30 

days after the effective date of 

this AD, whichever occurs later

For units manufactured in 2000, 

before exceeding 14,5 years 

since date of manufacture, or 

within 6 months after the effective 

date of this AD, whichever occurs 

later

For units manufactured in 2001, 

before exceeding 14 years since 

date of manufacture, or within 12 

months after the effective date of 

this AD, whichever occurs later

(3) From the effective date of this AD, it is allowed to install on any aeroplane a 

passenger oxygen generator with a P/N as listed in Table 1 of this AD, 

provided that the passenger oxygen generator has a manufacturing date of 

2005 or later.
