Under section 5 of the Federal Reserve Act 1 and Regulation I,2 a member bank must subscribe to capital stock of the Reserve Bank of its district in an amount equal to six percent of the member bank’s capital and surplus. The member bank must pay for one-half of this subscription when the Reserve Bank issues the capital stock, while the remaining half of the subscription shall be subject to call by the Board.3 Section 7(a)(1) of the Federal Reserve Act 4 provides that Reserve Bank stockholders with $10 billion or less in total consolidated assets shall receive a six percent dividend on paid-in capital stock, while stockholders with more than $10 billion in total consolidated assets shall receive a dividend on paidin capital stock equal to the lesser of six percent and ‘‘the rate equal to the high yield of the 10-year Treasury note auctioned at the last auction held prior to the payment of such dividend.’’ Section 7(a)(1) requires that the Board adjust the threshold for total consolidated assets annually to reflect the change in the Gross Domestic Product Price Index, published by the BEA. Regulation I implements section 7(a)(1) of the Federal Reserve Act by (1) defining the term ‘‘total consolidated assets,’’ 5 (2) incorporating the statutory dividend rates for Reserve Bank stockholders 6 and (3) providing that the Board shall adjust the threshold for total consolidated assets annually to reflect the change in the Gross Domestic Product Price Index.7 The Board has explained that it ‘‘expects to make this adjustment [to the threshold for total consolidated assets] using the final second quarter estimate of the Gross Domestic Product Price Index for each year, published by the Bureau of Economic Analysis.’’ 8 II. Adjustment The Board annually adjusts the $10 billion total consolidated asset threshold based on the change in the Gross Domestic Product Price Index between the second quarter of 2015 (the baseline year) and the second quarter of the current year.9 The second quarter U.S.C. 287.

The Board 2024 Gross Domestic Product Price Index estimate published by the BEA in September 2024 (124.942) is 28.41 percent higher than the second quarter 2015 Gross Domestic Product Price Index estimate published by the BEA in September 2024 (97.302). Based on this change in the Gross Domestic Product Price Index, the threshold for total consolidated assets in Regulation I will be $12,841,000,000 as of January 1, 2025. III. Administrative Law Matters Administrative Procedure Act The provisions of 5 U.S.C. 553(b) relating to notice of proposed rulemaking have not been followed in connection with the adoption of these amendments. The amendments involve expected, ministerial adjustments that are required by statute and Regulation I and are consistent with a method previously set forth by the Board.10 Accordingly, the Board finds good cause for determining, and so determines, that notice in accordance with 5 U.S.C. 553(b) is unnecessary. Regulatory Flexibility Act The Regulatory Flexibility Act (RFA) does not apply to a rulemaking where a general notice of proposed rulemaking is not required.11 As noted previously, the Board has determined that it is unnecessary to publish a general notice of proposed rulemaking for this final rule. Accordingly, the RFA’s requirements relating to an initial and final regulatory flexibility analysis do not apply. Paperwork Reduction Act In accordance with the Paperwork Reduction Act of 1995,12 the Board has reviewed this final rule. No collections of information pursuant to the Paperwork Reduction Act are contained in the final rule.

SUPPLEMENTARY INFORMATION: VerDate Sep<11>2014 15:54 Nov 08, 2024 Jkt 265001 Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2021–09–03, Amendment 39–21516 (86 FR 20266, April 19, 2021); corrected April 27, 2021 (86 FR 22111) (AD 2021–09–03). AD 2021–09–03 applied to certain Airbus Canada Limited Partnership Model BD– 500–1A10 and BD–500–1A11 airplanes. AD 2021–09–03 required repetitive replacements of the ELT antenna and repetitive inspections of the exterior fuselage skin around the ELT antenna attachment area. The FAA issued AD 2021–09–03 to address ELT antenna failure, which can lead to the loss of the ELT antenna and the development of fuselage cracks that can result in an inability to maintain cabin pressure. The NPRM published in the Federal Register on March 11, 2024 (89 FR 17343). The NPRM was prompted by AD CF–2022–67, dated December 6, 2022 (Transport Canada AD CF–2022– 67) (also referred to as the MCAI), issued by Transport Canada, which is the aviation authority for Canada. The MCAI states that since Transport Canada AD CF–2021–10 (corresponds to AD 2021–09–03) was issued, an aluminum ELT antenna has been made available to prevent ELT antenna failures resulting from vibration loads induced by air vortices shed by the Gogo 2Ku antenna radome. In addition, there was an in-service failure of an ELT antenna that occurred before the repetitive replacement interval required by Transport Canada AD CF–2021–10 was reached. The MCAI also states installation of the aluminum ELT antenna terminates the requirements of Transport Canada CF–2022–67, and that the applicability has been limited to airplanes on which the aluminum ELT antenna has not been installed in production. In the NPRM, the FAA proposed to continue to require the actions in AD 2021–09–03 and replacement of the ELT antenna with a new ELT antenna, inspection of the exterior fuselage skin around the ELT antenna attachment holes, and repair if necessary, as specified in Transport Canada AD CF– 2022–67. The FAA is issuing this AD to address ELT antenna failure, which can lead to the loss of the ELT antenna and the development of fuselage cracks that can result in an inability to maintain cabin pressure. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2024–0464. PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 88879 Discussion of Final Airworthiness Directive Comments The FAA received one comment from a single commenter, Delta Air Lines (Delta). The following presents the comment received on the NPRM and the FAA’s response to each comment. Request To Clarify Applicability Delta requested the FAA revise the applicability of the proposed AD to clarify it does not apply to airplanes that are not equipped with a Gogo 2Ku antenna radome, part number (P/N) P23743–605 or P/N P23743–606, as identified in the applicability of Transport Canada AD CF–2022–67. Delta stated that for AD 2021–09–03 (corresponding to Transport Canada AD CF–2021–10), the FAA clarified that if an airplane is not equipped with the part numbers identified in the applicability of Transport Canada AD CF–2021–10, then the requirements of AD 2021–09–03 do not apply to that airplane. As justification for its request, Delta noted that the applicability of Transport Canada AD CF–2021–10 mirrors the applicability of Transport Canada AD CF–2022–67. The FAA agrees that if an airplane is not equipped with an affected part number identified in the MCAI referenced in paragraph (c) of this AD, then this AD does not apply to that airplane. The FAA has not changed this AD in this regard. Conclusion 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 this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA reviewed the relevant data, considered the comment received, and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Material Incorporated by Reference Under 1 CFR Part 51 Transport Canada AD CF–2022–67 specifies procedures for: • Repetitive replacements of the ELT antenna with a new ELT antenna and repetitive inspections for damage (including cracking) of the exterior E:\FR\FM\12NOR1.SGM 12NOR1 88880 Federal Register / Vol. 89, No. 218 / Tuesday, November 12, 2024 / Rules and Regulations fuselage skin around the ELT antenna attachment area, and • A one-time replacement of the ELT antenna with a new aluminum ELT antenna, and detailed inspection for damage (including cracking) of the exterior fuselage skin around the ELT antenna attachment holes, and repair of any damage, which terminate the repetitive replacements and inspections. 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 the ADDRESSES section. Costs of Compliance The FAA estimates that this AD affects 56 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost Retained actions from AD 2021–09–03 ......... New actions .................................................... 4 work-hours × $85 per hour = $340 ............. 4 work-hours × $85 per hour = $340 ............. The FAA estimates the following costs to do any necessary on-condition actions that are required based on the Parts cost results of any required actions. The FAA has no way of determining the number $4,230 5,561 Cost per product $4,570 5,901 Cost on U.S. operators $255,920 330,456 of aircraft that might need these oncondition actions: ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Cost per product 4 work-hours × $85 per hour = $340 ...................................................................................................................... $2,000 $2,340 khammond on DSKJM1Z7X2PROD with RULES According to the manufacturer, some or all of the costs of this 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. Regulatory Findings This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on VerDate Sep<11>2014 15:54 Nov 08, 2024 Jkt 265001 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) 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.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2021-09-
03, which applied to certain Airbus Canada Limited Partnership Model 
BD-500-1A10 and BD-500-1A11 airplanes. AD 2021-09-03 required 
repetitive replacements of the emergency locator

[[Page 88879]]

transmitter (ELT) antenna and repetitive inspections of the exterior 
fuselage skin around the ELT antenna attachment area. This AD was 
prompted by a report that there was an in-service failure of an ELT 
antenna that occurred before the repetitive replacement interval 
required by AD 2021-09-03, and that a terminating action was developed. 
This AD continues to require the actions in AD 2021-09-03 and requires 
replacement of the ELT antenna with a new ELT antenna, inspection of 
the exterior fuselage skin around the ELT antenna attachment holes, and

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2021-09-03, Amendment 39-21516 (86 FR 
20266, April 19, 2021); corrected April 27, 2021 (86 FR 22111) (AD 
2021-09-03). AD 2021-09-03 applied to certain Airbus Canada Limited 
Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2021-09-03 
required repetitive replacements of the ELT antenna and repetitive 
inspections of the exterior fuselage skin around the ELT antenna 
attachment area. The FAA issued AD 2021-09-03 to address ELT antenna 
failure, which can lead to the loss of the ELT antenna and the 
development of fuselage cracks that can result in an inability to 
maintain cabin pressure.
    The NPRM published in the Federal Register on March 11, 2024 (89 FR 
17343). The NPRM was prompted by AD CF-2022-67, dated December 6, 2022 
(Transport Canada AD CF-2022-67) (also referred to as the MCAI), issued 
by Transport Canada, which is the aviation authority for Canada. The 
MCAI states that since Transport Canada AD CF-2021-10 (corresponds to 
AD 2021-09-03) was issued, an aluminum ELT antenna has been made 
available to prevent ELT antenna failures resulting from vibration 
loads induced by air vortices shed by the Gogo 2Ku antenna radome. In 
addition, there was an in-service failure of an ELT antenna that 
occurred before the repetitive replacement interval required by 
Transport Canada AD CF-2021-10 was reached. The MCAI also states 
installation of the aluminum ELT antenna terminates the requirements of 
Transport Canada CF-2022-67, and that the applicability has been 
limited to airplanes on which the aluminum ELT antenna has not been 
installed in production.
    In the NPRM, the FAA proposed to continue to require the actions in 
AD 2021-09-03 and replacement of the ELT antenna with a new ELT 
antenna, inspection of the exterior fuselage skin around the ELT 
antenna attachment holes, and repair if necessary, as specified in 
Transport Canada AD CF-2022-67. The FAA is issuing this AD to address 
ELT antenna failure, which can lead to the loss of the ELT antenna and 
the development of fuselage cracks that can result in an inability to 
maintain cabin pressure.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-0464.

Discussion of Final Airworthiness Directive

Comments

    The FAA received one comment from a single commenter, Delta Air 
Lines (Delta). The following presents the comment received on the NPRM 
and the FAA's response to each comment.

Request To Clarify Applicability

    Delta requested the FAA revise the applicability of the proposed AD 
to clarify it does not apply to airplanes that are not equipped with a 
Gogo 2Ku antenna radome, part number (P/N) P23743-605 or P/N P23743-
606, as identified in the applicability of Transport Canada AD CF-2022-
67. Delta stated that for AD 2021-09-03 (corresponding to Transport 
Canada AD CF-2021-10), the FAA clarified that if an airplane is not 
equipped with the part numbers identified in the applicability of 
Transport Canada AD CF-2021-10, then the requirements of AD 2021-09-03 
do not apply to that airplane. As justification for its request, Delta 
noted that the applicability of Transport Canada AD CF-2021-10 mirrors 
the applicability of Transport Canada AD CF-2022-67.
    The FAA agrees that if an airplane is not equipped with an affected 
part number identified in the MCAI referenced in paragraph (c) of this 
AD, then this AD does not apply to that airplane. The FAA has not 
changed this AD in this regard.

Conclusion

    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 this State of Design Authority, it 
has notified the FAA of the unsafe condition described in the MCAI 
referenced above. The FAA reviewed the relevant data, considered the 
comment received, and determined that air safety requires adopting this 
AD as proposed. Accordingly, the FAA is issuing this AD to address the 
unsafe condition on this product. Except for minor editorial changes, 
this AD is adopted as proposed in the NPRM. None of the changes will 
increase the economic burden on any operator.

Material Incorporated by Reference Under 1 CFR Part 51

    Transport Canada AD CF-2022-67 specifies procedures for:
     Repetitive replacements of the ELT antenna with a new ELT 
antenna and repetitive inspections for damage (including cracking) of 
the exterior

[[Page 88880]]

fuselage skin around the ELT antenna attachment area, and
     A one-time replacement of the ELT antenna with a new 
aluminum ELT antenna, and detailed inspection for damage (including 
cracking) of the exterior fuselage skin around the ELT antenna 
attachment holes, and repair of any damage, which terminate the 
repetitive replacements and inspections.
    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 the ADDRESSES section.

Costs of Compliance

    The FAA estimates that this AD affects 56 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators

Retained actions from AD 2021-09-03...  4 work-hours x $85 per            $4,230          $4,570        $255,920
                                         hour = $340.
New actions...........................  4 work-hours x $85 per             5,561           5,901         330,456
                                         hour = $340.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition actions that are 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
------------------------------------------------------------------------
4 work-hours x $85 per hour = $340....          $2,000           $2,340
------------------------------------------------------------------------

    According to the manufacturer, some or all of the costs of this 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.

Regulatory Findings

    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) 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.
