Federal Register / Vol. 90, No. 22 / Tuesday, February 4, 2025 / Proposed Rules 8915 

the proposed AD clarify that those 

airplanes that have not yet met the 

requirements of AD 2023–08–04 must 

still meet the inspection requirements of 

Boeing Alert Requirements Bulletin 

B787–81205–SB380021–00 RB, Issue 

001, dated August 12, 2022. 

The FAA agrees that the applicability 

of the NPRM did not include Model 

787–10 airplanes. Those airplanes had 

been removed from the applicability of 

the proposed AD because Boeing had 

originally stated that Model 787–10 

airplanes were delivered with safetystrap clamshell couplings on affected 

potable water lines, so those airplanes 

were not included in Boeing 

Requirements Bulletin B787–81205– 

SB250299–00 RB, Issue 001, dated July 

31, 2023 (the service information 

specified in paragraph (j) of the 

proposed AD). Accordingly, the NPRM 

stated that Model 787–10 airplanes were 

no longer subject to the unsafe 

condition and therefore not included in 

the applicability. However, as Boeing 

stated, there is a possibility that some 

Model 787–10 airplanes may have been 

in storage and not inspected as required 

by AD 2023–08–04 (and restated in 

retained paragraph (g) of the proposed 

AD). Therefore, if appropriate, those 

airplanes will be included in future 

rulemaking that addresses the unsafe 

condition. Because the NPRM is 

withdrawn, no further action is 

necessary for this NPRM. 

FAA’s Conclusions 

Upon further consideration, the FAA 

has determined that the NPRM would 

not adequately address the identified 

unsafe condition. Accordingly, the 

NPRM is withdrawn. AD 2023–08–04 

remains in effect unless it is later 

superseded. 

Regulatory Findings 

Since this action only withdraws an 

NPRM, it is neither a proposed nor a 

final rule. This action therefore is not 

covered under Executive Order 12866, 

the Regulatory Flexibility Act, or DOT 

Regulatory Policies and Procedures (44 

FR 11034, February 26, 1979).

This proposed AD was prompted by a 

determination that new or more 

restrictive airworthiness limitations are 

necessary. This proposed AD would 

require revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations. 

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–2023– 

65, dated October 3, 2023 (Transport 

Canada AD CF–2023–65) (also referred 

to after this as the MCAI), to correct an 

unsafe condition for certain Bombardier, 

Inc., Model BD–700–1A10 and BD–700– 

1A11 airplanes. The MCAI states that 

new or more restrictive airworthiness 

limitations have been developed. 

The FAA is proposing this AD to 

address new or more restrictive 

airworthiness limitations. Failure to 

adhere to the specified airworthiness 

limitations could adversely affect the 

stability and controllability of the 

airplane on landing and could result in 

damage to the airplane. You may 

examine the MCAI in the AD docket at 

regulations.gov under Docket No. FAA– 

2025–0016.

This material specifies new or more 

restrictive airworthiness limitations for 

safe life limits (for certain main landing 

gear and nose landing gear components) 

and certification maintenance 

requirements (for the shock strut axle 

and service door, pitch trim actuator, 

and nose landing gear shock-strut 

assembly to retraction-actuator mainfitting joint). These documents are 

distinct since they apply to different 

airplane models in different 

configurations. This material is 

reasonably available because the 

interested parties have access to it 

through their normal course of business 

or by the means identified in the 

ADDRESSES section. 

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 material 

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. 

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 (j)(1) of this proposed AD. 

Differences Between This Proposed AD 

and the MCAI 

Although the applicability of 

Transport Canada AD CF–2023–65 

includes Bombardier, Inc., Model BD– 

700–1A10 airplane having serial 

number 9001, that airplane is not 

included on the U.S. type certificate 

data sheet. Therefore, the applicability 

of this proposed AD does not include 

that airplane. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 484 

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 

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). 

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 


lotter on DSK11XQN23PROD with PROPOSALS1
Federal Register / Vol. 90, No. 22 / Tuesday, February 4, 2025 / Proposed Rules 8917 

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.

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–2025– 

0016; Project Identifier MCAI–2023– 

01047–T. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by March 21, 

2025. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Bombardier, Inc., 

Model BD–700–1A10 and BD–700–1A11 

airplanes, certificated in any category, having 

serial numbers (S/Ns) 9002 through 9879 

inclusive, 9998, and 60001 through 60065 

inclusive. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 05, Time Limits/Maintenance 

Checks. 

(e) Unsafe Condition 

This AD was prompted by a determination 

that new or more restrictive airworthiness 

limitations are necessary. The FAA is issuing 

this AD to address new or more restrictive 

airworthiness limitations. Failure to adhere 

to the specified airworthiness limitations 

could adversely affect the stability and 

controllability of the airplane on landing and 

could result in damage to the airplane. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Maintenance or Inspection Program 

Revision 

Within 60 days after the effective date of 

this AD, revise the existing maintenance or 

inspection program, as applicable, to 

incorporate the information specified in the 

tasks identified in table 1 to paragraph (g) of 

this AD, of Part 2, ‘‘Airworthiness 

Limitations,’’ of the applicable time limits/ 

maintenance checks (TLMC) manual 

identified in table 2 of this AD. The initial 

compliance time for doing the tasks is at the 

time specified in the applicable TLMC 

manual identified in table 2 to paragraph (g) 

of this AD, or within 60 days after the 

effective date of this AD, whichever occurs 

later, except as provided by paragraph (h) of 

this AD.

SUPPLEMENTARY INFORMATION: 

Authority for This Rulemaking 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

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. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority as it would 

amend the Class E airspace extending 

upward from 700 feet above the surface 

at Union County Airport, Marysville, 

OH, to support IFR operations at this 

airport. 

Comments Invited 

The FAA invites interested persons to 

participate in this rulemaking by 

submitting written comments, data, or 

views. Comments are specifically 

invited on the overall regulatory, 

aeronautical, economic, environmental, 

and energy-related aspects of the 

proposal. The most helpful comments 

reference a specific portion of the 

proposal, explain the reason for any 

recommended change, and include 

supporting data. To ensure the docket 

does not contain duplicate comments, 

commenters should submit only one 

time if comments are filed 

electronically, or commenters should 

send only one copy of written 

comments if comments are filed in 

writing. 

The FAA will file in the docket all 

comments it receives, as well as a report 

summarizing each substantive public 

contact with FAA personnel concerning 

this proposed rulemaking. Before acting 

on this proposal, the FAA will consider 

all comments it received on or before 

the closing date for comments. The FAA 

will consider comments filed after the 

comment period has closed if it is 

possible to do so without incurring
