SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2023–02–08, 

Amendment 39–22315 (88 FR 7867, 

February 7, 2023) (AD 2023–02–08). AD 

2023–02–08 applied to certain ATR–GIE 

Avions de Transport Re ́gional Model 

ATR42–500 airplanes. AD 2023–02–08 

required revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations. 

The FAA issued AD 2023–02–08 to 

prevent reduced structural integrity of 

the airplane. 

The NPRM published in the Federal 

Register on June 13, 2024 (89 FR 50241). 

The NPRM was prompted by AD 2024– 

0052, dated February 23, 2024, issued 

by EASA, which is the Technical Agent 

for the Member States of the European 

Union (EASA AD 2024–0052) (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 the requirements of AD 2023–02– 

08. The NPRM also proposed to require 

revising the existing maintenance or 

inspection program, as applicable, to 

incorporate new or more restrictive 

airworthiness limitations, as specified 

in EASA AD 2024–0052. The FAA is 

issuing this AD to address among other 

things, fatigue cracking and damage in 

principal structural elements. The 

unsafe condition, if not addressed, 

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–2024–1482.

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 

The FAA reviewed EASA AD 2024– 

0052 that revises the ATR42–400/–500 

Time Limits Document and incorporates 

EASA AD 2020–0249R1, which required 

a repetitive operational test for 

discrepancies of the stall warning 

system and stick pusher in the flight 

configuration for ATR–GIE Avions de 

Transport Re ́gional Model ATR42–500 

and ATR72 airplanes. This service 

information specifies new or more 

restrictive airworthiness limitations for 

airplane structures and safe life limits. 

EASA AD 2020–0249R1 revises EASA 

AD 2020–0249, which corresponds to 

FAA AD 2020–26–17, Amendment 39– 

21372 (85 FR 81795, December 17, 

2020) (AD 2020–26–17). 

This AD also requires EASA AD 

2022–0200, dated September 26, 2022, 

which the Director of the Federal 

Register approved for incorporation by 

reference as of March 14, 2023 (88 FR 

7867, February 7, 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 17 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 2023–02–08 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. 

List of Subjects in 14 CFR Part 39
