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:

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 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 89, No. 43 / Monday, March 4, 2024 / Proposed Rules 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 × 

$85 per work-hour). 

ESTIMATED COSTS FOR REQUIRED ACTIONS

product 

Cost on U.S.

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 

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 

■ 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: 

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 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 days after the effective date of this AD, 

whichever occurs later.
