Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF–2020–14, dated April 30, 2020 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Airbus Canada Limited Partnership Model BD–500– 1A10 and BD–500–1A11 airplanes. 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–2020– 0971. This proposed AD was prompted by a report that threaded fuel couplings were incorrectly installed at final assembly and in service. The FAA is proposing this AD to address loose fuel couplings, which could eventually disconnect and could lead to fuel starvation of the APU and pose a risk of fire. See the MCAI for additional background information. Related Service Information Under 1 CFR part 51 Airbus Canada has issued Service Bulletin BD500–282009, Issue 003, dated August 14, 2020. This service information describes procedures for repetitive functional tests of the APU fuel feed line shroud, a general visual inspection of the APU feed line shroud for any loose couplings, and tightening of any loose couplings if necessary. The inspection and tightening of the APU fuel feed line shroud couplings terminates the repetitive functional tests of the APU fuel feed line shroud. 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 the FAA’s 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 FAA 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 22 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS jbell on DSKJLSW7X2PROD with PROPOSALS Labor cost Up to 42 work-hours × $85 per hour = Up to $3,570 The FAA estimates the following costs to do any necessary on-condition actions that would be required based on VerDate Sep<11>2014 17:14 Oct 27, 2020 Jkt 253001 Parts cost Cost per product $0 Up to $3,570 ............................................................... the results of any required actions.

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. jbell on DSKJLSW7X2PROD with PROPOSALS List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-
500-1A11 airplanes. This proposed AD was prompted by a report that 
threaded fuel couplings were incorrectly installed at final assembly 
and in service. This proposed AD would require repetitive functional 
tests of the auxiliary power unit (APU) fuel feed line shroud, a 
general visual inspection of the APU feed line shroud for any loose 
couplings; and tightening any loose couplings, which would terminate 
the repetitive functional tests. The FAA is proposing this AD to 
address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by December 
14, 2020.

ADDRESSES: You may send comments, using the procedures found in 14 CFR

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2020-14, dated April 
30, 2020 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Airbus Canada Limited Partnership Model BD-500-
1A10 and BD-500-1A11 airplanes. 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-2020-0971.
    This proposed AD was prompted by a report that threaded fuel 
couplings were incorrectly installed at final assembly and in service. 
The FAA is proposing this AD to address loose fuel couplings, which 
could eventually disconnect and could lead to fuel starvation of the 
APU and pose a risk of fire. See the MCAI for additional background 
information.

Related Service Information Under 1 CFR part 51

    Airbus Canada has issued Service Bulletin BD500-282009, Issue 003, 
dated August 14, 2020. This service information describes procedures 
for repetitive functional tests of the APU fuel feed line shroud, a 
general visual inspection of the APU feed line shroud for any loose 
couplings, and tightening of any loose couplings if necessary. The 
inspection and tightening of the APU fuel feed line shroud couplings 
terminates the repetitive functional tests of the APU fuel feed line 
shroud. 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 the FAA's 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 FAA 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 22 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
----------------------------------------------------------------------------------------------------------------
Up to 42 work-hours x $85 per hour =                $0   Up to $3,570............  Up to $78,540.
 Up to $3,570.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any 
required actions. The FAA has no way of determining the number of 
aircraft that might need these on-condition actions:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
8 work-hours x $85 per hour = $680....              $0             $680
------------------------------------------------------------------------

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.

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:
