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 E:\FR\FM\04MRP1.SGM 04MRP1 15519 Federal Register / Vol. 89, No. 43 / Monday, March 4, 2024 / Proposed Rules 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 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 estimates the average total cost per operator to be $7,650 (90 work-hours × $85 per work-hour). 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 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 khammond on DSKJM1Z7X2PROD with PROPOSALS 16:26 Mar 01, 2024 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by 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 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive: ■ 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 VerDate Sep<11>2014 (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.

RIN 2120-AA64


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.

DATES: The FAA must receive comments on this proposed AD by April 18, 
2024.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

this rulemaking.

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).

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

    Air transportation, Aircraft, Aviation safety, Incorporation by 
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-

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
