Airworthiness Directives; Bombardier, Inc., Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. 
This AD was prompted by a determination that new or more restrictive 
airworthiness limitations for certain brake accumulators are necessary. 
This AD requires revising the existing maintenance or inspection 
program, as applicable, to incorporate new or more restrictive 
airworthiness limitations. This AD also requires determining the 
accumulated landings on the affected brake accumulators. The FAA is 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective January 15, 2025.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of January 15, 
2025.

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 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.

(e) Reason

    This AD was prompted by a determination that new or more 
restrictive airworthiness limitations for certain brake accumulators 
are necessary. 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, if not addressed, could result in 
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 
compliance time for doing the tasks is at the time specified in the 
tasks specified in table 1 to paragraph (g) of this AD, or within 90
