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 

certain Airbus SAS Model A318, A319, 

A320, and A321 airplanes. This 

proposed AD was prompted by a 

determination that new or more 

restrictive airworthiness limitations are 

necessary. This proposed AD would 

require revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations, 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 December 15, 

2023. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

Information (CBI) as described in the 

following paragraph, and other 

information as described in 14 CFR 

11.35, the FAA will post all comments 

received, without change, to 

regulations.gov, including any personal 

information you provide. The agency 

will also post a report summarizing each 

substantive verbal contact received 

about this NPRM. 

Confidential Business Information 

CBI is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

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, 

NY 11590; telephone 206–231–3367; 

email Timothy.P.Dowling@faa.gov. Any 

commentary that the FAA receives 

which is not specifically designated as 

CBI will be placed in the public docket 

for this rulemaking. 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2023–0138, 

dated July 13, 2023 (also referred to as 

the MCAI), to correct an unsafe 

condition for all Airbus SAS Model 

A318–111, A318–112, A318–121, A318– 

122, A319–111, A319–112, A319–113, 

A319–114, A319–115, A319–131, A319– 

132, A319–133, A319–151N, A319– 

153N, A319–171N, A320–211, A320– 

212, A320–214, A320–215, A320–216, 

A320–231, A320–232, A320–233, A320– 

251N, A320–252N, A320–253N, A320– 

271N, A320–272N, A320–273N, A321– 

111, A321–112, A321–131, A321–211, 

A321–212, A321–213, A321–231, A321– 

232, A321–251N, A321–251NX, A321– 

252N, A321–252NX, A321–253N, 

A321–253NX, A321–271N, A321– 

271NX, A321–272N and A321–272NX 

airplanes. Model A320–215 airplanes 

are not certificated by the FAA and are 

not included on the U.S. type certificate 

data sheet; this proposed AD therefore 

does not include those airplanes in the 

applicability. Airplanes with an original 

airworthiness certificate or original 

export certificate of airworthiness 

issued after May 12, 2023 must comply 

with the airworthiness limitations 

specified as part of the approved type 

design and referenced on the type 

certificate data sheet; this proposed AD 

therefore does not include those 

airplanes in the applicability. The MCAI 

states that new airworthiness limitations 

have been developed. 

EASA AD 2023–0138 specifies that it 

requires tasks (limitations) related to the 

lower deck cargo compartment (LDCC) 

fire protection system (FPS) already in 

Airbus A318/A319/A320/A321 ALS 

Part 3 Certification Maintenance 

Requirements (CMR), Revision 08, that 

is required by EASA AD 2022–0091 

dated May 20, 2022 (which corresponds 

to FAA AD 2023–04–06, Amendment 

39–22353 (88 FR 13665, March 6, 2023) 

(AD 2023–04–06)), and that 

incorporation of EASA AD 2023–0138 

invalidates (terminates) prior 

instructions for those tasks. This 

proposed AD therefore would terminate 

the limitations for task numbers: 

262300–00001–2–C, 262300–00001–3– 

C, 262300–00002–2–C, 262300–00004– 

2–C, 262300–00005–2–C, 262300– 

00006–2–C, 262300–00007–2–C, and 

262300–00008–1–C, as required by 

paragraph (o) of AD 2023–04–06. The 

EASA AD 2023–0138 also requires new 

tasks related to the air stop valve and 

cargo compartment fire extinguisher, 

respectively. 

The FAA is proposing this AD to 

address safety-significant latent failures 

(that are not annunciated), which, in 

combination with one or more other 

specific failures or events, could result 

in a hazardous or catastrophic failure 

condition. You may examine the MCAI 

in the AD docket at regulations.gov 

under Docket No. FAA–2023–2138. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed EASA AD 2023– 

0138, which specifies new or more 

restrictive airworthiness limitations. 

This service information 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 and service information 

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 new or more restrictive 

airworthiness limitations, which are 

specified in EASA AD 2023–0138 

described previously, as incorporated by 

reference. Any differences with EASA 

AD 2023–0138 are identified as 

exceptions in the regulatory text of this 

proposed AD. 


lotter on DSK11XQN23PROD with PROPOSALS1
74378 Federal Register / Vol. 88, No. 209 / Tuesday, October 31, 2023 / Proposed Rules 

This proposed AD would require 

revisions to certain operator 

maintenance documents to include new 

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 (k)(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 EASA AD 2023–0138 by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2023–0138 

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 2023–0138 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 2023–0138. 

Service information required by EASA 

AD 2023–0138 for compliance will be 

available at regulations.gov by searching 

for and locating Docket No. FAA–2023– 

2138 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 ‘‘New 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 1,680 

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 has 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.
