Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF–2019–26, dated July 9, 2019 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc., Model CL–600–1A11 (600), CL–600– 2A12 (601), and CL–600–2B16 (601–3A, 601–3R, and 604 Variants) airplanes. This proposed AD was prompted by a report that fast and easy access to the portable oxygen bottle may be prevented by the portable oxygen bottle installation’s upper bracket latch assembly catching on the pressure gauge tube or on the pressure gauge bezel of the portable oxygen bottle. The FAA is proposing this AD to address this condition, which, if not detected and corrected, could prevent fast and easy access to the portable oxygen bottle in an emergency situation. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 Bombardier has issued the following service information: • Bombardier Service Bulletin 600– 0772, dated June 29, 2018; • Bombardier Service Bulletin 601– 0646, dated June 29, 2018; • Bombardier Service Bulletin 604– 35–006, dated June 29, 2018; E:\FR\FM\23MRP1.SGM 23MRP1 Federal Register / Vol. 85, No. 56 / Monday, March 23, 2020 / Proposed Rules • Bombardier Service Bulletin 605– 35–005, dated June 29, 2018; • Bombardier Service Bulletin 650– 35–001, dated June 29, 2018. This service information describes procedures for a check to identify the manufacturer and part number of the portable oxygen bottle installation, and, if necessary, modification of the portable oxygen bottle installation. These documents are distinct since they apply to different airplane models. 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. FAA’s Determination This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to a bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI and service information referenced above. The FAA is proposing this AD because the agency evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed Requirements of This NPRM This proposed AD would require accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Differences Between this Proposed AD and the MCAI or Service Information.’’ 16285 Differences Between This Proposed AD and the MCAI or Service Information The MCAI specifies that airplanes having serial numbers not listed in the applicable service information must do certain actions in accordance with the applicable service information. This proposed AD would require airplanes having serial numbers not listed in the applicable service information to do those actions in accordance with the procedures specified in paragraph (j)(2) of this proposed AD. Costs of Compliance The FAA estimates that this proposed AD affects 188 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product 3 work-hours × $85 per hour = $255 per installation.. $1,530 per installation .................. $1,785 per installation .................. 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. The FAA is 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. jbell on DSKJLSW7X2PROD with PROPOSALS Regulatory Findings The FAA 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: VerDate Sep<11>2014 16:52 Mar 20, 2020 Jkt 250001 (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and (3) 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.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2019-26, dated July 9, 
2019 (referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for 
certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), 
and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes.
    This proposed AD was prompted by a report that fast and easy access 
to the portable oxygen bottle may be prevented by the portable oxygen 
bottle installation's upper bracket latch assembly catching on the 
pressure gauge tube or on the pressure gauge bezel of the portable 
oxygen bottle. The FAA is proposing this AD to address this condition, 
which, if not detected and corrected, could prevent fast and easy 
access to the portable oxygen bottle in an emergency situation. See the 
MCAI for additional background information.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued the following service information:
     Bombardier Service Bulletin 600-0772, dated June 29, 2018;
     Bombardier Service Bulletin 601-0646, dated June 29, 2018;
     Bombardier Service Bulletin 604-35-006, dated June 29, 
2018;

[[Page 16285]]

     Bombardier Service Bulletin 605-35-005, dated June 29, 
2018;
     Bombardier Service Bulletin 650-35-001, dated June 29, 
2018.
    This service information describes procedures for a check to 
identify the manufacturer and part number of the portable oxygen bottle 
installation, and, if necessary, modification of the portable oxygen 
bottle installation. These documents are distinct since they apply to 
different airplane models. 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.

FAA's Determination

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to a bilateral agreement with the State of Design Authority, the FAA 
has been notified of the unsafe condition described in the MCAI and 
service information referenced above. The FAA is proposing this AD 
because the agency evaluated all the relevant information and 
determined the unsafe condition described previously is likely to exist 
or develop on other products of the same type design.

Proposed Requirements of This NPRM

    This proposed AD would require accomplishing the actions specified 
in the service information described previously, except as discussed 
under ``Differences Between this Proposed AD and the MCAI or Service 
Information.''

Differences Between This Proposed AD and the MCAI or Service 
Information

    The MCAI specifies that airplanes having serial numbers not listed 
in the applicable service information must do certain actions in 
accordance with the applicable service information. This proposed AD 
would require airplanes having serial numbers not listed in the 
applicable service information to do those actions in accordance with 
the procedures specified in paragraph (j)(2) of this proposed AD.

Costs of Compliance

    The FAA estimates that this proposed AD affects 188 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
              Labor cost                      Parts cost            Cost per product      Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
3 work-hours x $85 per hour = $255     $1,530 per installation  $1,785 per installation  $335,580 per
 per installation..                                                                       installation
----------------------------------------------------------------------------------------------------------------

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.
    The FAA is 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

    The FAA 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) Will not affect intrastate aviation in Alaska, and
    (3) 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.

(d) Subject

    Air Transport Association (ATA) of America Code 35, Oxygen.

(e) Reason

    This AD was prompted by a report that fast and easy access to 
the portable oxygen bottle may be prevented by the portable oxygen 
bottle installation's upper bracket latch assembly catching on the 
pressure gauge tube or on the pressure gauge bezel of the portable 
oxygen bottle. The FAA is proposing this AD to address this 
condition, which, if not detected and corrected, could prevent fast 
and easy access to the portable oxygen bottle in an emergency 
situation.

(f) Compliance

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