SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2023–03–09, 

Amendment 39–22334 (88 FR 12139, 

February 27, 2023) (AD 2023–03–09). 

AD 2023–03–09 applied to certain ATR– 

GIE Avions de Transport Re ́gional 

Model ATR72–101, –102, –201, –202, 

–211, –212, and –212A airplanes. AD 

2023–03–09 required revising the 

existing maintenance or inspection 

program, as applicable, to incorporate 

new or more restrictive airworthiness 

limitations. The FAA issued AD 2023– 

03–09 to address fatigue cracking and 

damage in principal structural elements, 

which could result in reduced structural 

integrity of the airplane. 

The NPRM published in the Federal 

Register on August 20, 2024 (89 FR 

67329). The NPRM was prompted by 

AD 2024–0053, dated February 23, 

2024, issued by EASA, which is the 

Technical Agent for the Member States 

of the European Union (EASA AD 2024– 

0053) (also referred to as the MCAI). The 

MCAI states that new or more restrictive 

airworthiness limitations have been 

developed. 

In the NPRM, the FAA proposed to 

continue to require the actions in AD 

2023–03–09 and to require revising the 

existing maintenance or inspection 

program, as applicable, to incorporate 

new or more restrictive airworthiness 

limitations, as specified in EASA AD 

2024–0053. The FAA is issuing this AD 

to address fatigue cracking and damage 

in principal structural elements, which 

could result in reduced structural 

integrity of the airplane. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2024–2128. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from 

Air Line Pilots Association, 

International (ALPA), who supported 

the NPRM without change. 

Conclusion 

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 

reviewed the relevant data, considered 

the comment received, and determined 

that air safety requires adopting this AD 

as proposed. Accordingly, the FAA is 

issuing this AD to address the unsafe 

condition on this product. Except for 

minor editorial changes, this AD is 

adopted as proposed in the NPRM. 

None of the changes will increase the 

economic burden on any operator. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

EASA AD 2024–0053, dated February 

23, 2024, specifies new or more 

restrictive airworthiness limitations for 

airplane structures and safe life limits. 

EASA AD 2024–0053 states that the new 

limitations include repetitive 

operational tests as required by EASA 

AD 2020–0249R1, dated November 30, 

2021 (EASA AD 2020–0249R1). 

This AD also requires EASA AD 

2022–0201, dated September 26, 2022, 

which the Director of the Federal 

Register approved for incorporation by 

reference as of April 3, 2023 (88 FR 

12139, February 27, 2023). 

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. 

Related AD 

EASA AD 2020–0249, dated 

November 11, 2020, corresponds to FAA 

AD 2020–26–17, Amendment 39–21372 

(85 FR 81795, December 17, 2020) (AD 

2020–26–17), which applies to Model 

ATR42 and ATR72 airplanes. 

Accomplishing the revision of the 

existing maintenance or inspection 

program required by paragraph (j) of this 

AD terminates the requirements of AD 

2020–26–17 for Model ATR72 airplanes. 

Costs of Compliance 

The FAA estimates that this AD 

affects 41 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this 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. 

The FAA estimates the total cost per 

operator for the new actions to be 

$7,650 (90 work-hours × $85 per workhour). 

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 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will 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 that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Will not affect intrastate aviation 

in Alaska, and 

(3) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2023–05– 

02, which applied to certain Airbus SAS 

Model A318, A319, A320, and A321 

series airplanes. AD 2023–05–02 

required revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations. 

This AD was prompted by a 

determination that new or more 

restrictive airworthiness limitations are 

necessary. This AD requires revising the 

existing maintenance or inspection 

program, as applicable, to incorporate 

additional new or more restrictive 

airworthiness limitations, as specified 

in a European Union Aviation Safety 

Agency (EASA) AD, which is 

incorporated by reference. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective January 13, 

2025. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of January 13, 2025. 

The Director of the Federal Register

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2023–05–02, 

Amendment 39–22371 (88 FR 15600, 

March 14, 2023) (AD 2023–05–02). AD 

2023–05–02 applied to certain Airbus 

SAS Model A318, A319, A320, and 

A321 series airplanes. AD 2023–05–02 

required revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations. 

The FAA issued AD 2023–05–02 to 

address the risks associated with the 

effects of aging on airplane systems. 

The NPRM published in the Federal 

Register on September 11, 2024 (89 FR 

73608). The NPRM was prompted by 

AD 2024–0046, dated February 19, 

2024, issued by EASA, which is the 

Technical Agent for the Member States 

of the European Union (EASA AD 2024– 

0046) (also referred to as the MCAI). The 

MCAI states that new or more restrictive 

airworthiness limitations have been 

developed. 

In the NPRM, the FAA proposed to 

retain all of the requirements of EASA 

AD 2023–05–02. The FAA also 

proposed to require revising the existing 

maintenance or inspection program, as 

applicable, to incorporate additional 

new or more restrictive airworthiness 

limitations, as specified in EASA AD 

2024–0046. The FAA is issuing this AD 

to address the risks associated with the 

effects of aging on airplane systems. 

Such effects could change system 

characteristics. The unsafe condition, if 

not addressed, could result in an 

increased potential for failure of certain 

life-limited parts, and reduced 

structural integrity of the airplane. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2024–2139. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from 

three commenters, including Air Line 

Pilots Association, International (ALPA) 

and two individuals, who supported the 

NPRM without change. 

Conclusion 

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 

reviewed the relevant data, considered 

the comments received, and determined
