SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Zodiac Aerotechnics (formerly Intertechnique Aircraft Systems) flightcrew oxygen mask regulators as installed on, but not limited to, various transport and small airplanes. The NPRM published in the Federal Register on April 22, 2015 (80 FR 22438). 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 VerDate Sep<11>2014 17:28 Nov 19, 2015 Jkt 238001 Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Zodiac Aerotechnics (formerly Intertechnique Aircraft Systems) flightcrew oxygen mask regulators as installed on, but not limited to, various transport and small airplanes. 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/ #!documentDetail;D=FAA-2015-09270004. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (80 FR 22438, April 22, 2015) and the FAA’s response to each comment. Boeing concurred with the contents of the NPRM. Request To Revise the Air Transport Association (ATA) Code Horizon Air requested that we change the ATA code specified in paragraph (d) of the proposed AD (80 FR 22438, April 22, 2015) to ‘‘35.’’ The commenter stated that the correct ATA code for oxygen is ATA 35. We agree with the commenter because this AD addresses an unsafe condition for certain oxygen mask regulators. We have removed the ATA code of ‘‘28’’ and instead we have referred to ATA code ‘‘35’’ in paragraph (d) of this AD. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the PO 00000 Frm 00023 Fmt 4700 Sfmt 4700 72577 public interest require adopting this AD with the change described previously and minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (80 FR 22438, April 22, 2015) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (80 FR 22438, April 22, 2015). We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. 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. 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 AD. Costs of Compliance We estimate that this AD affects 13 airplanes of U.S. registry. We also estimate that it will take about 3 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $225 per product. Based on these figures, we estimate the cost of this 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. E:\FR\FM\20NOR1.SGM 20NOR1 72578 Federal Register / Vol. 80, No. 224 / Friday, November 20, 2015 / Rules and Regulations Regulatory Findings We determined that this AD will not have federalism implications under Executive Order 13132. This AD will 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 that this AD: 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.

Airworthiness Directives; Zodiac Aerotechnics (Formerly 
Intertechnique Aircraft Systems)

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting 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 AD was prompted by a report 
that improper maintenance on oxygen mask regulators was found. This AD 
requires the identification and replacement of all potentially affected 
units. This AD also requires installation of a placard and revision of 
the airplane flight manual to include an operational procedure for use 
in case of depressurization. We are issuing this AD to detect and 
correct affected oxygen mask regulators, which could lead to inadequate 
protection to the affected flightcrew against hypoxia.

[[Page 72577]]

Hypoxia can start from a headache and drowsiness and lead eventually to 
unconsciousness with severe consequence in terms of airplane 
controllability.

DATES: This AD becomes effective December 28, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 28, 
2015.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Zodiac Aerotechnics 
(formerly Intertechnique Aircraft Systems) flightcrew oxygen mask 
regulators as installed on, but not limited to, various transport and 
small airplanes. The NPRM published in the Federal Register on April 
22, 2015 (80 FR 22438).
    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 certain Zodiac 
Aerotechnics (formerly Intertechnique Aircraft Systems) flightcrew 
oxygen mask regulators as installed on, but not limited to, various 
transport and small airplanes. 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/#!documentDetail;D=FAA-2015-0927-0004.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (80 
FR 22438, April 22, 2015) and the FAA's response to each comment. 
Boeing concurred with the contents of the NPRM.

Request To Revise the Air Transport Association (ATA) Code

    Horizon Air requested that we change the ATA code specified in 
paragraph (d) of the proposed AD (80 FR 22438, April 22, 2015) to 
``35.'' The commenter stated that the correct ATA code for oxygen is 
ATA 35.
    We agree with the commenter because this AD addresses an unsafe 
condition for certain oxygen mask regulators. We have removed the ATA 
code of ``28'' and instead we have referred to ATA code ``35'' in 
paragraph (d) of this AD.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the change described previously and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (80 FR 22438, April 22, 2015) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 22438, April 22, 2015).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

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. 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 AD.

Costs of Compliance

    We estimate that this AD affects 13 airplanes of U.S. registry.
    We also estimate that it will take about 3 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts will cost about $225 per 
product. Based on these figures, we estimate the cost of this 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 AD will not have federalism implications 
under Executive Order 13132. This AD will 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 that this AD:
    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.

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

2015-23-09 Zodiac Aerotechnics (formerly Intertechnique Aircraft 
Systems): Amendment 39-18325. FAA-2015-0927; Directorate Identifier 
2013-NM-172-AD.

(a) Effective Date

    This AD becomes effective December 28, 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 1, 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 having part number MC10-04-127 with serial number 48573 is

    (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 35, Oxygen.

(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.

    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.''
