Executive Order 12866 (Regulatory Planning and Review), Executive Order 13563 (Improving Regulation and Regulatory Review), and Executive Order 14094 (Modernizing Regulatory Review) Executive Orders 12866, 13563, and 14094 direct agencies to assess all costs and benefits of available regulatory alternatives, and, if regulation is necessary, to select regulatory approaches that maximize net benefits (including potential economic, environmental, public health and safety effects, distributive impacts, and equity). OMB’s Office of Information and Regulatory Affairs (OIRA) designated the implementation of the Uniform Guidance by OMB and more than 25 other agencies to be not significant in 2014. USAGM similar concludes that its implementation is not significant and therefore is not subject to mandatory prior review by the OIRA pursuant to Executive Orders 12866, 13563, or 14094. e. Executive Order 13132 (Federalism Assessment) Executive Order 13132 limits an agency’s ability to promulgate rules that have federalism implications, impose substantial compliance costs on state and local governments, or pre-empt state and local law. This proposed rule will not have sufficient federalism implications to warrant the preparation of a federalism assessment pursuant to Executive Order 13132. List of Subjects in 2 CFR Part 1900 Accounting, Administrative practice and procedure, Grant programs, Grants administration, Loan programs, Nonprofit organizations, Reporting and recordkeeping requirements. For the reasons discussed in the preamble, and under the authority of 5 U.S.C. 301 and 2 CFR part 200, the U.S. Agency for Global Media adds chapter XIX to 2 CFR subtitle B, consisting of parts 1900 through 1999, and removes 22 CFR part 518 as follows: Title 2—Grants and Agreements Subtitle B—Federal Agency Regulations for Grants and Agreements c. Unfunded Mandates Reform Act of 1995 The Unfunded Mandates Reform Act requires that agencies prepare a budgetary impact statement before promulgating a rule that may result in the expenditure by State, local, and tribal governments, or by the private sector, of $100 million or more in any one year. Upon first implementing the Uniform Guidance, OMB determined that its joint interim final rule will not result in expenditures by State, local, and tribal governments, or by the private sector, of $100 million or more in any one year. USAGM concurs. Therefore, no actions are necessary under the provisions of the Unfunded Mandates Reform Act of 1995, 2 U.S.C. 1532. CHAPTER XIX—U.S. AGENCY FOR GLOBAL MEDIA d. Regulatory Flexibility Act The Regulatory Flexibility Act requires an agency issuing a final rule to provide a final regulatory flexibility analysis or to certify that the rule will not have a significant economic impact on a substantial number of small entities. In accordance with the RFA, USAGM certifies that this rule will not have a significant economic impact on a substantial number of small entities, and thus no regulatory flexibility analysis is required under 5 U.S.C. 603. The United States Agency for Global Media adopts the Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards set forth at 2 CFR part 200. Thus, this part gives regulatory effect to the terms of 2 CFR part 200 (as effective October 1, 2024).

SUPPLEMENTARY INFORMATION: lotter on DSK11XQN23PROD with RULES1 Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Bombardier, Inc., Model BD–700–1A10 and BD–700–1A11 airplanes. The NPRM published in the Federal Register on March 4, 2024 (89 FR 15517). The NPRM was prompted by AD CF–2022–25, dated May 17, 2022 (referred to after this as the MCAI), issued by Transport Canada, which is the aviation authority for Canada. The MCAI states that new or more restrictive airworthiness limitations (life limits) for certain brake accumulators have been developed, following in-service failures of brake accumulators on other types of airplanes with similar components. A brake accumulator surpassing a life limit could fail and result in loss of hydraulic pressure on the associated hydraulic system, which services the main and emergency/parking brakes on the main landing gear. In the NPRM, the FAA proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations for certain brake accumulators and to determine the accumulated landings on the affected brake accumulators. The FAA is issuing this AD to address brake accumulators that could surpass a life limit and fail, resulting in loss of hydraulic pressure on the associated hydraulic system, which services the main and emergency/parking brakes on the main landing gear. The unsafe condition on these products could result in reduced or total loss of available braking and a possible runway excursion. VerDate Sep<11>2014 16:09 Dec 10, 2024 Jkt 265001 You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2024–0228. Discussion of Final Airworthiness Directive Comments The FAA received comments from three individuals who supported the NPRM without change. The FAA received an additional comment from an individual who stated that accounting for the accumulated landings is a better method of gauging the necessity of maintenance or inspection on the brake accumulators since the accumulator is used in ground towing operations and to dampen sudden pressure changes in the aircraft’s hydraulics during operation. The commenter stated another factor that might be accounted for is a potential difference in temperature during operation, especially if the brake accumulators in the Bombardier airplanes mentioned in the airworthiness directive have air (instead of nitrogen) as the fluid inside the accumulator. The FAA agrees that the accumulated landings is the appropriate method of establishing the intervals for maintenance or inspection of the brake accumulators, as specified in the TLMCs. Reference to difference in temperature is unnecessary, as the currently stated calendar time requirements and accumulated landing requirements adequately and appropriately define the timing requirements of the needed actions. This methodology is consistent with that used by Transport Canada. The FAA has not changed the AD with regards to this issue. 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 comments 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.

The FAA also reviewed the following material, which specifies procedures for determining the accumulated landings on the brake accumulators. Knowing the accumulated landings is necessary to comply with the life limit. These documents are distinct because they apply to different airplane configurations. • Bombardier Service Bulletin 700– 1A11–32–030, Revision 02, dated March 2, 2023. • Bombardier Service Bulletin 700– 32–043, Revision 02, dated March 2, 2023. • Bombardier Service Bulletin 700– 32–5020, Revision 02, dated March 2, 2023. • Bombardier Service Bulletin 700– 32–5506, Revision 02, dated March 2, 2023. • Bombardier Service Bulletin 700– 32–6020, Revision 02, dated March 2, 2023. • Bombardier Service Bulletin 700– 32–6506, Revision 02, dated March 2, 2023. 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 117 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: The FAA has determined that revising the maintenance or inspection program takes an average of 90 work-hours per operator, although the agency recognizes that this number may vary from operator to operator. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. Therefore, the agency estimates the average total cost per operator to be $7,650 (90 work-hours × $85 per work-hour). lotter on DSK11XQN23PROD with RULES1 ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 1.5 work-hours × $85 per hour = $128 ....................................................................................... $0 $128 $14,976 Authority for This Rulemaking Regulatory Findings 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 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.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain Bombardier, 
Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published 
in the Federal Register on March 4, 2024 (89 FR 15517). The NPRM was 
prompted by AD CF-2022-25, dated May 17, 2022 (referred to after this 
as the MCAI), issued by Transport Canada, which is the aviation 
authority for Canada. The MCAI states that new or more restrictive 
airworthiness limitations (life limits) for certain brake accumulators 
have been developed, following in-service failures of brake 
accumulators on other types of airplanes with similar components. A 
brake accumulator surpassing a life limit could fail and result in loss 
of hydraulic pressure on the associated hydraulic system, which 
services the main and emergency/parking brakes on the main landing 
gear.
    In the NPRM, the FAA proposed to require revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations for certain brake 
accumulators and to determine the accumulated landings on the affected 
brake accumulators. The FAA is issuing this AD to address brake 
accumulators that could surpass a life limit and fail, resulting in 
loss of hydraulic pressure on the associated hydraulic system, which 
services the main and emergency/parking brakes on the main landing 
gear. The unsafe condition on these products could result in reduced or 
total loss of available braking and a possible runway excursion.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-0228.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from three individuals who supported the 
NPRM without change.
    The FAA received an additional comment from an individual who 
stated that accounting for the accumulated landings is a better method 
of gauging the necessity of maintenance or inspection on the brake 
accumulators since the accumulator is used in ground towing operations 
and to dampen sudden pressure changes in the aircraft's hydraulics 
during operation. The commenter stated another factor that might be 
accounted for is a potential difference in temperature during 
operation, especially if the brake accumulators in the Bombardier 
airplanes mentioned in the airworthiness directive have air (instead of 
nitrogen) as the fluid inside the accumulator.
    The FAA agrees that the accumulated landings is the appropriate 
method of establishing the intervals for maintenance or inspection of 
the brake accumulators, as specified in the TLMCs. Reference to 
difference in temperature is unnecessary, as the currently stated 
calendar time requirements and accumulated landing requirements 
adequately and appropriately define the timing requirements of the 
needed actions. This methodology is consistent with that used by 
Transport Canada. The FAA has not changed the AD with regards to this 
issue.

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 
comments 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.

    The FAA also reviewed the following material, which specifies 
procedures for determining the accumulated landings on the brake 
accumulators. Knowing the accumulated landings is necessary to comply 
with the life limit. These documents are distinct because they apply to 
different airplane configurations.

    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 117 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:
    The FAA has determined that revising the maintenance or inspection 
program takes an average of 90 work-hours per operator, although the 
agency recognizes that this number may vary from operator to operator. 
Since operators incorporate maintenance or inspection program changes 
for their affected fleet(s), the FAA has determined that a per-operator 
estimate is more accurate than a per-airplane estimate. Therefore, the 
agency estimates the average total cost per operator to be $7,650 (90 
work-hours x $85 per work-hour).

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.

reduced or total loss of available braking and a possible runway 
excursion.

(f) Compliance

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

(g) Maintenance or Inspection Program Revision

    Within 90 days after the effective date of this AD, revise the 
existing maintenance or inspection program, as applicable, to 
incorporate the information in the tasks specified in table 1 to 
paragraph (g) of this AD of Section 5-10-11, ``Life Limits 
(Systems),'' of Part 2, ``Airworthiness Limitations,'' of the 
applicable Time Limits/Maintenance Checks (TLMC) Manual. The initial
