Airworthiness Directives; Bombardier, Inc., Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11
airplanes. This proposed AD was prompted by a determination that new or
more restrictive airworthiness limitations for certain brake
accumulators are necessary. This proposed AD would require revising the
existing maintenance or inspection program, as applicable, to
incorporate new or more restrictive airworthiness limitations. This
proposed AD would also require determining the accumulated landings on
the affected brake accumulators. The FAA is proposing this AD to
address the unsafe condition on these products.

Background
Transport Canada, which is the aviation authority for Canada, has
issued Transport Canada AD CF-2022-25, dated May 3, 2022 (Transport
Canada AD CF-2022-25) (also referred to after this as the MCAI), to
correct an unsafe condition on certain Bombardier, Inc., Model BD-700-
1A10 and BD-700-1A11 airplanes. 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. The unsafe condition, if not addressed, could result in reduced
or total loss of available braking and a possible runway excursion.
The FAA is proposing this AD to address the unsafe condition on
these products. You may examine the MCAI in the AD docket at
regulations.gov under Docket No. FAA-2024-0228.

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 this State of Design Authority,
the FAA has been notified of the unsafe condition described in the MCAI
and service information referenced above. The FAA is proposing this AD
because the FAA evaluated all the relevant information and determined
the unsafe condition described previously is likely to exist or develop
on other products of the same type design.
Proposed Requirements of This NPRM
This proposed AD would require revising the existing maintenance or
inspection program, as applicable, to incorporate new or more
restrictive airworthiness limitations for certain brake accumulators.
This proposed AD also would require determining the accumulated
landings on the affected brake accumulators.
This proposed AD would require revisions to certain operator
maintenance documents to include new actions (e.g., inspections).
Compliance with these actions is required by 14 CFR 91.403(c). For
airplanes that have been previously modified, altered, or repaired in
the areas addressed by this proposed AD, the operator may not be able
to accomplish the actions described in the revisions. In this
situation, to comply with 14 CFR 91.403(c), the operator must request
approval for an alternative method of compliance according to paragraph
(k)(1) of this proposed AD.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 117 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
The FAA has determined that revising the maintenance or inspection
program
[[Page 15519]]
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).
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
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

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:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
Bombardier, Inc.: Docket No. FAA-2024-0228; Project Identifier MCAI-
2022-00599-T.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by April 18, 2024.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Bombardier, Inc., Model BD-700-1A10 and BD-
700-1A11 airplanes, serial numbers 9002 through 9998 inclusive, and
60001 through 60046 inclusive.
(d) Subject
Air Transport Association (ATA) of America Code 05, Time Limits/
Maintenance Checks; 32, Landing Gear.
(e) Reason
This AD was prompted by a determination that new or more

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
days after the effective date of this AD, whichever occurs later.
