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. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed the following Bombardier material.

                     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). Estimated Costs for Required Actions

 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.
