## EASA AIRWORTHINESS DIRECTIVE

AD No

. : 2012

- 0 254 R1

Date: 21 December 2012

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 E U 748/2012 , Part 21

. A.3B. In accordance with EC 2042/2003 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 requ irements of that AD

, unless otherwise specified by the Agency

[EC 2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exempt ion]

.

### ATA 35 Oxygen

– Flight Crew Oxygen Mask Regulator

– Identification /

Operational Procedure / Re placement

Manufacturer(s): Intertechnique ( EROS )

Applicability: F light c rew o xygen m ask r egulators

, having P art N umber (P/N) MC10 , MF10

and MF20 series

, with serial numbers (s/n) as listed in Appendix 1 of this AD.

The affected f light c rew o xygen m asks r egulators are known to be installed on,

but not limited to, aeroplanes manufactured by Airbus, ATR, Boeing,

Bombardier (formerly Canadair, De Havilland Canada), Cessna, Gulfstream

and McDonnell Douglas.

Reason: In a repair station, improper maintenance on oxygen mask regulators was

reported to Intertechnique : d uring an inspection of the oxygen test bench by its

manufacturer, incorrect settings were noticed. This test bench setting

discrepancy on the oxygen mask regulator could cause an improper mask

dilution schedule.

This condition, if not detected and corrected, could lead, in case of a diversion

above 10 000 f ee t after a depressurization event, to the inhalation of air with

improper content of oxygen, due to the bad dilution settings , thereby providing

inadequate protection to the affected flight crew member against hypoxia,

which can start from a headache and drowsiness and lead eventually to

unconsciousness with severe consequen ce in term of aeroplane controllability.

For the reasons described above, this AD requires the identification and

re placement of all potentially affected units . This AD also requires installation of

a placard and implementation of an operational pro c ed ure pending replacement

of the affected units.E ASA AD No.: 2012

paragraph (2) of this AD within 30 days after the effective date of the original

issue of this AD.

Effective Date: Revision 1 : 2 1 December 2012

Origin a l issue: 13 December 2012

Required

A ction(s) and

Compliance

Time(s) : Required as indicated, unless accomplished previously:

(1) Within 30 days after 13 December 2012 [ the effective date of the original

issue of th is AD ]

, i nspect each flight crew oxygen mask regulator to identify

the P/N and s / n in accordance with the instructions of Intertechnique

Service Bulletin (SB) MCF

- SBU

- 001

.

A review of aeroplane maintenance records is acceptable to make the

determination as specified in this paragraph, provided those records can

be relied upon for that purpose, and each flight crew oxygen mask

regulator can be conclusively identified from that review.

(2) If the P/N and s/n

, identified as required by paragraph ( 1 ) of this AD, are

listed in Appendix 1 of this AD

, within 30 days after 13 December 2012 [the

effective date of the original issue of this AD]

, accomplish the actions of

either paragraph (2.1) or (2.2) of this AD :

(2.1) Replace each affected f light c rew o xygen m ask r egulator with a

serviceable part

, not having a P/N and s/n as listed in Appendix 1 of

this AD , or with a part that has passed the test in accordance with

the instructions of paragraph 3.A.(4) of Intertechnique SB MCF

.

(2.2) A mend the Aircraft Flight Manual (AFM) and install a placard, as

follows:

Aircraft Flight Manual

In case of depressurisation, both pilots must use the mask regulator

on 100% Demand mode or Emergency mode only.

Insertion of a copy of this procedure into the applicable AFM is

acceptable to comply with this requirement

NOTE 1 : For oxygen over

- consumption , refer to applicable

aeroplane type certificate holder limitations, if existing, depending on

the aeroplane configuration and/or flight plan.

NOTE 2: I t is the operators’ responsibility to assess the operational

consequences of the oxygen over

- consumption and ensure that the

operational requirements with regard to Supplemental o xygen and

Crew protective breathing equipment are still complied with.

Operators are expected to amend , as applicable, their operations

manual(s) accordingly.

Placard installation

Fabricate and install a placard on the flight crew oxygen mask

container that states:

USE SELECTOR on “ 100% ” OR “ EMERGENCY ” ONLY

(3) Within 12 months after 13 December 2012 [the effective date of the original

issue of this AD]

, unless already accomplished as required by paragraph

(2.1) of this AD, replace each affected flight crew oxygen mask regulator

with a serviceable part, not having a P/N and s/n as listed in Appendix 1 of

this AD, or with a part that has passed the test in accordance with the

instructions of paragraph 3.A.(4) of Intertechnique SB MCF
