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 


ddrumheller on DSK120RN23PROD with RULES1
97506 Federal Register / Vol. 89, No. 236 / Monday, December 9, 2024 / Rules and Regulations 

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 2024–0046 specifies new or 

more restrictive airworthiness 

limitations for airplane structures and 

safe life limits. 

This AD also requires EASA AD 

2022–0102, dated June 8, 2022, which 

the Director of the Federal Register 

approved for incorporation by reference 

as of April 18, 2023 (88 FR 15600, 

March 14, 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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 1,920 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this AD: 

The FAA estimates the total cost per 

operator for the retained actions from 

AD 2023–05–02 to be $7,650 (90 workhours × $85 per work-hour). 

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.
