PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF–2019–18, dated May 10, 2019 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc., Model BD–700–1A10 and BD–700– 1A11 airplanes. The MCAI states: Bombardier Inc. has discovered that easy removal of the portable oxygen bottle from its support bracket may not always be possible on some portable oxygen bottle installations due to the latch of the upper bracket assembly catching on the pressure gauge tube or on the pressure gauge bezel of the portable oxygen bottle. The portable oxygen bottle is required to be accessible for use by cabin crew members in emergency situations. This [Canadian] AD requires installation of a modified top bracket and new middle bracket on all affected portable oxygen bottle installations to improve portable oxygen bottle accessibility. You may examine the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2019– 0725. Related Service Information Under 1 CFR Part 51 Bombardier has issued the following service information. The service information describes procedures for installation of a modified top bracket and new middle bracket on all affected portable oxygen bottle installations. These documents are distinct since they apply to different airplane models in different configurations. • Service Bulletin 700–1A11–35–013, dated July 3, 2018. • Service Bulletin 700–35–014, dated July 3, 2018. • Service Bulletin 700–35–5003, Revision 01, dated November 23, 2018. • Service Bulletin 700–35–6003, Revision 02, dated November 23, 2018. 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 our bilateral agreement with the State of E:\FR\FM\29OCP1.SGM 29OCP1 57830 Federal Register / Vol. 84, No. 209 / Tuesday, October 29, 2019 / Proposed Rules 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 the relevant information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. Costs of Compliance Proposed Requirements of This NPRM This proposed AD would require accomplishing the actions specified in the service information described previously. The FAA estimates that this proposed AD affects 108 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 2 work-hours × $85 per hour = $170 per installation ...... $1,575 per installation ....... $1,745 per installation ....... According to the manufacturer, some or all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all known costs in the cost estimate. 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. This proposed AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes and associated appliances to the Director of the System Oversight Division. Regulatory Findings The FAA determined that this proposed AD would not have federalism implications under Executive Order VerDate Sep<11>2014 20:38 Oct 28, 2019 Jkt 250001 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by 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 1.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2019-18, dated May 10, 
2019 (referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for 
certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. 
The MCAI states:

    Bombardier Inc. has discovered that easy removal of the portable 
oxygen bottle from its support bracket may not always be possible on 
some portable oxygen bottle installations due to the latch of the 
upper bracket assembly catching on the pressure gauge tube or on the 
pressure gauge bezel of the portable oxygen bottle. The portable 
oxygen bottle is required to be accessible for use by cabin crew 
members in emergency situations. This [Canadian] AD requires 
installation of a modified top bracket and new middle bracket on all 
affected portable oxygen bottle installations to improve portable 
oxygen bottle accessibility.

    You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2019-
0725.

Related Service Information Under 1 CFR Part 51

     Service Bulletin 700-35-014, dated July 3, 2018.
     Service Bulletin 700-35-5003, Revision 01, dated November 
23, 2018.
     Service Bulletin 700-35-6003, Revision 02, dated November 
23, 2018.
    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 our bilateral agreement with the State of

[[Page 57830]]

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 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.

Costs of Compliance

    The FAA estimates that this proposed AD affects 108 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
----------------------------------------------------------------------------------------------------------------
2 work-hours x $85 per hour = $170     $1,575 per installation  $1,745 per installation  $188,460 per
 per installation.                                                                        installation.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some or all of the costs of this 
proposed AD may be covered under warranty, thereby reducing the cost 
impact on affected individuals. The FAA does not control warranty 
coverage for affected individuals. As a result, the FAA has included 
all known costs in the cost estimate.

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.
    This proposed AD is issued in accordance with authority delegated 
by the Executive Director, Aircraft Certification Service, as 
authorized by FAA Order 8000.51C. In accordance with that order, 
issuance of ADs is normally a function of the Compliance and 
Airworthiness Division, but during this transition period, the 
Executive Director has delegated the authority to issue ADs applicable 
to transport category airplanes and associated appliances to the 
Director of the System Oversight Division.

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.

List of Subjects in 14 CFR Part 39
