Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background Transport Canada, which is the aviation authority for Canada, has issued Transport Canada AD CF–2022– 08, dated March 3, 2022 (Transport Canada AD CF–2022–08) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all Airbus Canada Limited Partnership (Type Certificate previously held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Model BD–500–1A10 and BD–500– 1A11 airplanes. The MCAI states there have been several in-service findings of mechanical wear damage on the engine fuel feed system tubes and fuel tube connections on airplanes that are ‘‘postSB BD500–282004’’ or that have the production equivalent. Transport Canada AD CF–2019–19R1, dated November 1, 2019 (Transport Canada AD CF–2019–19R1), among other actions, mandates modifying the fuel feed line installations in the fuel collector tanks using ACLP Service Bulletin BD500–282004, Issue 1, dated August 30, 2019. Transport Canada AD CF–2019–19R1 corresponds to FAA AD 2022–02–07, Amendment 39–21904 (87 FR 7027, February 8, 2022). This proposed AD would require repetitive inspections of the fuel feed system for damage and replacement if necessary, as specified in Transport Canada AD CF–2022–08, which is proposed for incorporation by reference. The FAA is proposing this AD to address mechanical wear damage on the engine fuel feed system tubes and fuel tube connections. The unsafe condition, if not addressed, could result in failure of the affected fuel tubes and subsequent failure of the gravity transfer system, which could lead to a fuel imbalance resulting in a reduction in aircraft functional capabilities and PO 00000 Frm 00010 Fmt 4702 Sfmt 4702 increased crew workload. See the MCAI for additional background information. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2022–1566. Related Service Information Under 1 CFR Part 51 Transport Canada AD CF–2022–08 specifies procedures for repetitive general visual inspections for mechanical wear damage (damage includes cracks, scores, scratches, nicks, and gouges) of the fuel feed system (the fuel feed tubes, related attaching hardware, and the area where the saddle clamp was installed), and rectification, such as replacement if any discrepancy is found after measuring any damage found during any inspection. This material is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in ADDRESSES. 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, it has notified the FAA of the unsafe condition described in the MCAI described above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in Transport Canada AD CF–2022–08 described previously, as incorporated by reference, except for any group identified as exceptions in the regulatory text of this proposed AD. Explanation of Required Compliance Information In the FAA’s ongoing efforts to improve the efficiency of the AD process, the FAA developed a process to use some civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, the FAA proposes to incorporate Transport Canada AD CF– 2022–08 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with Transport Canada AD CF–2022–08 in its entirety through that incorporation, E:\FR\FM\06DEP1.SGM 06DEP1 Federal Register / Vol. 87, No. 233 / Tuesday, December 6, 2022 / Proposed Rules except for any differences identified as exceptions in the regulatory text of this proposed AD. Service information required by Transport Canada AD CF– 2022–08 for compliance will be available at regulations.gov under Docket No. FAA–2022–1566 after the FAA final rule is published. Interim Action The FAA considers that this proposed AD would be an interim action. This AD is considered interim action and further AD action may follow. 74529 Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 69 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 74 work-hours × $85 per hour = $6,290 ..................................................................................... $0 $6,290 $434,010 ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost 7 work-hours × $85 per hour = $595 ................................................................................................................... $57,284 The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some or all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected operators. 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. lotter on DSK11XQN23PROD with PROPOSALS1 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. VerDate Sep<11>2014 17:01 Dec 05, 2022 Jkt 259001 For the reasons discussed above, I certify this proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Would not affect intrastate aviation in Alaska, and (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

Background

    Transport Canada, which is the aviation authority for Canada, has 
issued Transport Canada AD CF-2022-08, dated March 3, 2022 (Transport 
Canada AD CF-2022-08) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for all Airbus Canada Limited Partnership (Type Certificate previously 
held by C Series Aircraft Limited Partnership (CSALP); Bombardier, 
Inc.) Model BD-500-1A10 and BD-500-1A11 airplanes. The MCAI states 
there have been several in-service findings of mechanical wear damage 
on the engine fuel feed system tubes and fuel tube connections on 
airplanes that are ``post-SB BD500-282004'' or that have the production 
equivalent. Transport Canada AD CF-2019-19R1, dated November 1, 2019 
(Transport Canada AD CF-2019-19R1), among other actions, mandates 
modifying the fuel feed line installations in the fuel collector tanks 
using ACLP Service Bulletin BD500-282004, Issue 1, dated August 30, 
2019. Transport Canada AD CF-2019-19R1 corresponds to FAA AD 2022-02-
07, Amendment 39-21904 (87 FR 7027, February 8, 2022).
    This proposed AD would require repetitive inspections of the fuel 
feed system for damage and replacement if necessary, as specified in 
Transport Canada AD CF-2022-08, which is proposed for incorporation by 
reference. The FAA is proposing this AD to address mechanical wear 
damage on the engine fuel feed system tubes and fuel tube connections. 
The unsafe condition, if not addressed, could result in failure of the 
affected fuel tubes and subsequent failure of the gravity transfer 
system, which could lead to a fuel imbalance resulting in a reduction 
in aircraft functional capabilities and increased crew workload. See 
the MCAI for additional background information.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1566.

Related Service Information Under 1 CFR Part 51

    Transport Canada AD CF-2022-08 specifies procedures for repetitive 
general visual inspections for mechanical wear damage (damage includes 
cracks, scores, scratches, nicks, and gouges) of the fuel feed system 
(the fuel feed tubes, related attaching hardware, and the area where 
the saddle clamp was installed), and rectification, such as replacement 
if any discrepancy is found after measuring any damage found during any 
inspection.
    This material is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in ADDRESSES.

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, it 
has notified the FAA of the unsafe condition described in the MCAI 
described above. The FAA is issuing this NPRM after determining that 
the unsafe condition described previously is likely to exist or develop 
in other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in Transport Canada AD CF-2022-08 described previously, as incorporated 
by reference, except for any group identified as exceptions in the 
regulatory text of this proposed AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA developed a process to use some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, the 
FAA proposes to incorporate Transport Canada AD CF-2022-08 by reference 
in the FAA final rule. This proposed AD would, therefore, require 
compliance with Transport Canada AD CF-2022-08 in its entirety through 
that incorporation,

[[Page 74529]]

except for any differences identified as exceptions in the regulatory 
text of this proposed AD. Service information required by Transport 
Canada AD CF-2022-08 for compliance will be available at 
regulations.gov under Docket No. FAA-2022-1566 after the FAA final rule 
is published.

Interim Action

    The FAA considers that this proposed AD would be an interim action. 
This AD is considered interim action and further AD action may follow.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 69 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
74 work-hours x $85 per hour = $6,290........................              $0           $6,290         $434,010
----------------------------------------------------------------------------------------------------------------


                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
           Labor cost               Parts cost       Cost per  product
------------------------------------------------------------------------
7 work-hours x $85 per hour =           $57,284   Up to $57,879.
 $595.
------------------------------------------------------------------------

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some or all of the costs of 
this proposed AD may be covered under warranty, thereby reducing the 
cost impact on affected operators.

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) Would not affect intrastate aviation in Alaska, and
    (3) Would 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:
