We propose to adopt a new airworthiness directive (AD) for certain Zodiac Aerotechnics (formerly Intertechnique Aircraft Systems) flightcrew oxygen mask regulators as installed on, but not limited to, various transport and small airplanes. This proposed AD was prompted by a report that improper maintenance on oxygen mask regulators was found. This proposed AD would require the identification and replacement of all potentially affected units. This proposed AD also would require installation of a placard and revision of the airplane flight manual to include an operational procedure for use in case of depressurization. We are proposing this AD to detect and correct affected oxygen mask regulators, which could lead to inadequate protection to the affected flightcrew against hypoxia. Hypoxia can start from a headache and drowsiness and lead eventually to unconsciousness with severe consequence in terms of airplane controllability.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Zodiac Aerotechnics (formerly Intertechnique Aircraft Systems) 
flightcrew oxygen mask regulators as installed on, but not limited to, 
various transport and small airplanes. This proposed AD was prompted by 
a report that improper maintenance on oxygen mask regulators was found. 
This proposed AD would require the identification and replacement of 
all potentially affected units. This proposed AD also would require 
installation of a placard and revision of the airplane flight manual to 
include an operational procedure for use in case of depressurization. 
We are proposing this AD to detect and correct affected oxygen mask 
regulators, which could lead to inadequate protection to the affected 
flightcrew against hypoxia. Hypoxia can start from a headache and 
drowsiness and lead eventually to unconsciousness with severe 
consequence in terms of airplane controllability.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2012-0254R1, dated December 21, 2012 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    In a repair station, improper maintenance on [flightcrew] oxygen 
mask regulators was reported to Intertechnique: during 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 feet 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 flightcrew member against hypoxia, which 
can start from a headache and drowsiness and lead eventually to 
unconsciousness with severe consequence in term of aeroplane 
controllability.
    For the reasons described above, this [EASA] AD requires the 
identification and replacement of all potentially affected units. 
This [EASA] AD also requires installation of a placard and [a 
revision to the airplane flight manual to include] . . . an 
operational procedure [in case of depressurization] pending 
replacement of the affected units.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating it in Docket No. 
FAA-2015-0927.

Related Service Information Under 1 CFR Part 51

    Zodiac Services has issued Zodiac Aerospace Service Bulletin MCF-
SBU-35-001, Revision 1, dated December 3, 2012. The service information 
describes procedures for the identification and replacement of all 
potentially affected units. The actions described in this service 
information are intended to correct the unsafe condition identified in 
the MCAI. This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section of this 
NPRM.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects 13 appliances installed 
on, but not limited to, various transport and small airplanes of U.S. 
registry.
    We also estimate that it would take about 3 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost about $225 
per product. Based on these figures, we estimate the cost of this 
proposed AD on U.S. operators to be $6,240, or $480 per product.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a substantial direct effect on the States, on the relationship 
between the national Government and the States, or on the distribution 
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Zodiac Aerotechnics (formerly Intertechnique Aircraft Systems): 
Docket No. FAA-2015-0927; Directorate Identifier 2013-NM-172-AD.

(a) Comments Due Date

    We must receive comments by June 8, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Zodiac Aerotechnics (formerly Intertechnique 
Aircraft Systems) flightcrew oxygen mask regulators having part 
number MC10, MF10, and MF20 series, with serial numbers listed in 
Appendix 1 of Zodiac Services Service Bulletin MCF-SBU-35-001, 
Revision 01, dated December 3, 2012. These oxygen mask regulators 
are installed on various transport and small airplanes, certificated 
in any category, including, but not limited to, the airplanes of the 
manufacturers specified in paragraphs (c)(1), (c)(2), (c)(3), 
(c)(4), (c)(5), (c)(6), and (c)(7) of this AD. An oxygen mask 
regulator

[[Page 22440]]

having part number MC10-04-127 with serial number 48573 is affected 
only if it is part of part number MSE101-27 with serial number 7521.
    (1) Airbus.
    (2) ATR--GIE Avions de Transport R[eacute]gional.
    (3) The Boeing Company.
    (4) Bombardier, Inc.
    (5) Cessna Aircraft Company.
    (6) Gulfstream Aerospace Corporation.
    (7) Gulfstream Aerospace LP.

(d) Subject

    Air Transport Association (ATA) of America Code 26, Fire 
Protection.

(e) Reason

    This AD was prompted by a report that improper maintenance on 
oxygen mask regulators was found. During an inspection of the oxygen 
test bench, incorrect settings were noticed. This test bench setting 
discrepancy on the oxygen mask regulator could cause an improper 
mask dilution schedule. We are issuing this AD to detect and correct 
affected oxygen mask regulators, which could lead, in case of mask 
usage at or above 10,000 feet 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 flightcrew against hypoxia. Hypoxia can start from a 
headache and drowsiness and lead eventually to unconsciousness with 
severe consequence in terms of airplane controllability.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Inspection

    Within 30 days after the effective date of this AD, inspect each 
flightcrew oxygen mask regulator to identify the part number and 
serial number, in accordance with the Accomplishment Instructions of 
Zodiac Aerospace Service Bulletin MCF-SBU-35-001, Revision 1, dated 
December 3, 2012. A review of airplane 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 
flightcrew oxygen mask regulator can be conclusively identified from 
that review.

(h) Action for Affected Regulators

    If the part number and serial number, identified as required by 
paragraph (g) of this AD, are listed in Appendix 1 of Zodiac 
Aerospace Service Bulletin MCF-SBU-35-001, Revision 1, dated 
December 3, 2012, within 30 days after the effective date of this 
AD, accomplish the actions specified in paragraph (h)(1) or (h)(2) 
of this AD.
    (1) Replace each affected flightcrew oxygen mask regulator with 
a part identified in paragraph (h)(1)(i) or (h)(1)(ii) of this AD.

    Note 1 to paragraph (h)(2)(i) of this AD:  For oxygen over-
consumption, refer to applicable airplane type certificate holder 
limitations, if existing, depending on the airplane configuration 
and/or flight plan.


    Note 2 to paragraph (h)(2)(i) of this AD:  It is the operators' 
responsibility to assess the operational consequences of the oxygen 
over-consumption and ensure that the operational requirements with 
regard to supplemental oxygen and crew protective breathing 
equipment are still done. Operators are expected to amend, as 
applicable, their operations manual(s) accordingly.

    (ii) Fabricate and install a placard on the flightcrew oxygen 
mask container that states: ``USE SELECTOR on ``100%'' OR 
``EMERGENCY'' ONLY.''

(i) Regulator Replacement

    Within 12 months after the effective date of this AD, unless 
already accomplished as specified in paragraph (h)(1) of this AD, 
replace each affected flightcrew oxygen mask regulator identified in 
paragraph (h) of this AD with a part identified in paragraph (i)(1) 
or (i)(2) of this AD. After replacement of all affected flightcrew 
oxygen mask regulators on an airplane, the actions specified in 
paragraph (h)(2) of this AD are no longer required, the AFM revision 
specified in paragraph (h)(2)(i) of this AD may be removed from the 
AFM, and the placard identified in paragraph (h)(2)(ii) of this AD 
may be removed from the airplane.
    (1) A serviceable part, not having a part number and serial 
number listed in Appendix 1 of Zodiac Aerospace Service Bulletin
