Airworthiness Directives; Airbus SAS 

Airplanes 

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 SAS Model A321–251NX, 

–252NX, –253NX, –271NX, and –272NX 

airplanes. This proposed AD was 

prompted by discovery of two bushes 

that had migrated on the latch shaft of 

an emergency overwing exit door 

(OWED) during accomplishment of an 

inspection on an in-service airplane. 

This proposed AD would require 

repetitive detailed inspections (DETs) of 

the affected parts and, in case of 

discrepancies, modification of the 

affected parts, and would prohibit the 

installation of affected parts, as 

specified in a European Union Aviation 

Safety Agency (EASA) AD, which is 

proposed for incorporation by reference 

(IBR). 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 7, 2025. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this NPRM 

contain commercial or financial 

information that is customarily treated 

as private, that you actually treat as 

private, and that is relevant or 

responsive to this NPRM, it is important 

that you clearly designate the submitted 

comments as CBI. Please mark each 

page of your submission containing CBI 

as ‘‘PROPIN.’’ The FAA will treat such 

marked submissions as confidential 

under the FOIA, and they will not be 

placed in the public docket of this 

NPRM. Submissions containing CBI 

should be sent to Timothy Dowling, 

Aviation Safety Engineer, FAA, 1600 

Stewart Avenue, Suite 410, Westbury,

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2024–0187, 

dated September 25, 2024 (EASA AD 

2024–0187) (also referred to as the 

MCAI), to correct an unsafe condition 

for all Airbus SAS Model A321–251NX, 

–252NX, –253NX, –271NX, and –272NX 

airplanes. The MCAI states during 

accomplishment of an inspection on an 

in-service airplane, two bushes were 

found migrated on the latch shaft of an 

OWED. This condition, if not detected 

and corrected, could affect the fatigue 

life of the lower beam of the OWED and, 

consequently, 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–2025–0008.

6842 Federal Register / Vol. 90, No. 12 / Tuesday, January 21, 2025 / Proposed Rules 

Material Incorporated by Reference 

Under 1 CFR Part 51 

EASA AD 2024–0187 specifies 

procedures for repetitive DETs for 

discrepancies of the affected parts and, 

in case of discrepancies, modification of 

discrepant parts. Accomplishment of 

the modification terminates the 

repetitive inspections. Discrepancies 

include any signs of bush migration or 

deterioration of the sealant between the 

bush and latch bracket. EASA AD 2024– 

0187 also prohibits the installation of 

affected parts. 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, 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 

accomplishing the actions specified in 

EASA AD 2024–0187 described 

previously, except for any differences 

identified as exceptions in the 

regulatory text 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 EASA AD 2024–0187 by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2024–0187 

in its entirety through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD. 

Using common terms that are the same 

as the heading of a particular section in 

EASA AD 2024–0187 does not mean 

that operators need comply only with 

that section. For example, where the AD 

requirement refers to ‘‘all required 

actions and compliance times,’’ 

compliance with this AD requirement is 

not limited to the section titled 

‘‘Required Action(s) and Compliance 

Time(s)’’ in EASA AD 2024–0187. 

Material required by EASA AD 2024– 

0187 for compliance will be available at 

regulations.gov under Docket No. FAA– 

2025–0008 after the FAA final rule is 

published. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 284 

airplanes of U.S. registry. The FAA 

estimates the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product Cost on U.S. operators 

3 work-hours × $85 per hour = $255 ........................... $0 $255 $72,420 per inspection cycle. 

The FAA estimates the following 

costs to do any on-condition action that 

would be required based on the results 

of any required actions. The FAA has no 

way of determining the number of 

aircraft that might need this oncondition action: 

ESTIMATED COSTS OF ON-CONDITION ACTIONS

Labor cost Parts cost Cost per 

product 

51 work-hours × $85 per hour = $4,335 ................................................................................................................. $2,150 $6,485 

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.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 


ddrumheller on DSK120RN23PROD with PROPOSALS1
Federal Register / Vol. 90, No. 12 / Tuesday, January 21, 2025 / Proposed Rules 6843 

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: 

Airbus SAS: Docket No. FAA–2025–0008; 

Project Identifier MCAI–2024–00563–T. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by March 7, 

2025. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all Airbus SAS Model 

A321–251NX, –252NX, –253NX, –271NX, 

and –272NX airplanes, certificated in any 

category. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 52, Doors. 

(e) Unsafe Condition 

This AD was prompted by discovery of two 

bushes that had migrated on the latch shaft 

of an emergency overwing exit door (OWED) 

during accomplishment of an inspection on 

an in-service airplane. The FAA is issuing 

this AD to address bush migration on the 

latch shaft. The unsafe condition, if not 

addressed, could affect the fatigue life of the 

lower beam of the OWED and, consequently, 

the structural integrity of the airplane. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraphs (h) and 

(i) of this AD: Comply with all required 

actions and compliance times specified in, 

and in accordance with, European Union 

Aviation Safety Agency AD 2024–0187, dated 

September 25, 2024 (EASA AD 2024–0187). 

(h) Exceptions to EASA AD 2024–0187 

(1) Where EASA AD 2024–0187 refers to its 

effective date, this AD requires using the 

effective date of this AD. 

(2) Where paragraph (2) of EASA AD 2024– 

0187 states ‘‘discrepancies, as defined in the 

ISB,’’ this AD requires replacing that text 

with ‘‘any signs of bush migration or 

deterioration of the sealant between the bush 

and latch bracket.’’ 

(3) This AD does not adopt the ‘‘Remarks’’ 

section of EASA AD 2024–0187. 

(i) No Reporting Requirement 

Although the material referenced in EASA 

AD 2024–0187 specifies to submit certain 

information to the manufacturer, this AD 

does not include that requirement. 

(j) Additional AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, AIR–520, Continued 

Operational Safety Branch, FAA, has the 

authority to approve AMOCs for this AD, if 

requested using the procedures found in 14 

CFR 39.19. In accordance with 14 CFR 39.19, 

send your request to your principal inspector 

or responsible Flight Standards Office, as 

appropriate. If sending information directly 

to the manager of the Continued Operational 

Safety Branch, send it to the attention of the 

person identified in paragraph (k) of this AD 

and email to: AMOC@faa.gov. Before using 

any approved AMOC, notify your appropriate 

principal inspector, or lacking a principal 

inspector, the manager of the responsible 

Flight Standards Office. 

(2) Contacting the Manufacturer: For any 

requirement in this AD to obtain instructions 

from a manufacturer, the instructions must 

be accomplished using a method approved 

by the Manager, AIR–520, Continued 

Operational Safety Branch, FAA; or EASA; or 

Airbus SAS’s EASA Design Organization 

Approval (DOA). If approved by the DOA, 

the approval must include the DOAauthorized signature. 

(3) Required for Compliance (RC): Except 

as required by paragraph (i) and (j)(2) of this 

AD, if any material contains procedures or 

tests that are identified as RC, those 

procedures and tests must be done to comply 

with this AD; any procedures or tests that are 

not identified as RC are recommended. Those 

procedures and tests that are not identified 

as RC may be deviated from using accepted 

methods in accordance with the operator’s 

maintenance or inspection program without 

obtaining approval of an AMOC, provided 

the procedures and tests identified as RC can 

be done and the airplane can be put back in 

an airworthy condition. Any substitutions or 

changes to procedures or tests identified as 

RC require approval of an AMOC.
