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 the 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: 

■ a. Removing Airworthiness Directive 

2023–12–17, Amendment 39–22475 (88 

FR 42604, July 3, 2023); and 

■ b. Adding the following new AD: 

Pilatus Aircraft Ltd.: Docket No. FAA–2024– 

0045; Project Identifier MCAI–2023– 

01088–A. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by March 18, 

2024. 

(b) Affected ADs 

This AD replaces AD 2023–12–17, 

Amendment 39–22475 (AD 2023–12–17). 

(c) Applicability 

This AD applies to Pilatus Aircraft Ltd. 

Model PC–12, PC–12/45, PC–12/47, and PC–

Background 

Transport Canada, which is the 

aviation authority for Canada, has 

issued Transport Canada AD CF–2023– 

41, dated June 15, 2023 (Transport 

Canada AD CF–2023–41) (also referred 

to as the MCAI), to correct an unsafe 

condition on certain MHI RJ Aviation 

ULC Model CL–600–2B19 (Regional Jet 

Series 100 & 440) airplanes. The MCAI 

states that a more restrictive 

airworthiness limitation has been 

developed due to reports of an unclear 

effectivity for airworthiness limitation 

(AWL) task number 53–41–180 in the 

Maintenance Requirements Manual 

(MRM), Part 2. If the revised task, AWL 

number 53–41–180, is not performed at 

the required intervals, failures of the 

strap modification to the fuselage 

station (FS) 409 and 128 bulkhead could 

remain undetected and could result in 

the loss of the structural integrity of the 

airplane. 

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–2024–0219. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Transport Canada 

AD CF–2023–41, which specifies a more 

restrictive airworthiness limitation for 

AWL task number 53–41–180. 

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 ADDRESSES. 

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, it has notified the 

FAA of the unsafe condition described 

in the MCAI referenced above. The FAA 

is issuing this NPRM after determining 

that the unsafe condition described 

previously is likely to exist or develop 

in other products of the same type 

design. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

revising the existing maintenance or 

inspection program, as applicable, to 

incorporate or a more restrictive 

airworthiness limitation, which is 

specified in Transport Canada AD CF– 

2023–41 described previously, as 

incorporated by reference. Any 

difference with Transport Canada AD 

CF–2023–41 are identified as exceptions 

in the regulatory text of this proposed 

AD. 

This proposed AD would require 

revisions to certain operator 

maintenance documents to include new 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 89, No. 23 / Friday, February 2, 2024 / Proposed Rules 7301 

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 (AMOC) 

according to paragraph (j)(1) of this 

proposed AD. 

Explanation of Required Compliance 

Information 

In the FAA’s ongoing efforts to 

improve the efficiency of the AD 

process, the FAA developed a process to 

use some civil aviation authority (CAA) 

ADs as the primary source of 

information for compliance with 

requirements for corresponding FAA 

ADs. The FAA has been coordinating 

this process with manufacturers and 

CAAs. As a result, the FAA proposes to 

incorporate Transport Canada AD CF– 

2023–41 by reference in the FAA final 

rule. This proposed AD would, 

therefore, require compliance with 

Transport Canada AD CF–2023–41 in its 

entirety through that incorporation, 

except for any differences identified as 

exceptions in the regulatory text of this 

proposed AD. Service information 

required by Transport Canada AD CF– 

2023–41 for compliance will be 

available at regulations.gov under 

Docket No. FAA–2024–0219 after the 

FAA final rule is published. 

Airworthiness Limitation ADs Using 

the New Process 

The FAA’s process of incorporating 

by reference MCAI ADs as the primary 

source of information for compliance 

with corresponding FAA ADs has been 

limited to certain MCAI ADs (primarily 

those with service bulletins as the 

primary source of information for 

accomplishing the actions required by 

the FAA AD). However, the FAA is now 

expanding the process to include MCAI 

ADs that require a change to 

airworthiness limitation documents, 

such as airworthiness limitation 

sections. 

For these ADs that incorporate by 

reference an MCAI AD that changes 

airworthiness limitations, the FAA 

requirements are unchanged. Operators 

must revise the existing maintenance or 

inspection program, as applicable, to 

incorporate the information specified in 

the new airworthiness limitation 

document. The airworthiness 

limitations must be followed according 

to 14 CFR 91.403(c) and 91.409(e). 

The previous format of the 

airworthiness limitation ADs included a 

paragraph that specified that no 

alternative actions (e.g., inspections) or 

intervals may be used unless the actions 

and intervals are approved as an AMOC 

in accordance with the procedures 

specified in the AMOC paragraph under 

‘‘Additional AD Provisions.’’ This new 

format includes a ‘‘Provisions for 

Alternative Actions and Intervals’’ 

paragraph that does not specifically 

refer to AMOCs, but operators may still 

request an AMOC to use an alternative 

action or interval. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 78 

airplanes of U.S. registry. The FAA 

estimates the following costs to comply 

with this proposed AD: 

The FAA has determined that revising 

the existing maintenance or inspection 

program takes an average of 90 workhours 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 

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.

Airworthiness Directives; Airbus 

Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for all 

Airbus Helicopters Model AS332C, 

AS332C1, AS3322L, AS332L1, 

AS332L2, and EC225LP helicopters. 

This proposed AD was prompted by a 

report of cracks on the fuel filter bowl 

(bowl) due to over-torquing. This 

proposed AD would require visually 

inspecting the bowls of the right hand 

(RH) and left hand (LH) fuel filters for 

any cracks and seepage. Depending on 

the inspection results, this proposed AD 

would require removing an affected fuel 

filter from service and replacing that 

part. This proposed AD would also 

allow a certain fuel filter to be installed 

on a helicopter if certain actions are 

accomplished, as specified in a 

European Union Aviation Safety Agency 

(EASA) AD, which is proposed for 

incorporation by reference. 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 March 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:
