Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2025-11-02, which applies to certain Airbus SAS Model A319-151N, -153N, -171N, and -173N airplanes; A320-251N, -252N, -253N, -271N, -272N, and -273N airplanes; A321-251N, -251NX, -252N, -252NX, -253N, -253NX, - 253NY, -271N, -271NX, -272N, and -272NX airplanes. AD 2025-11-02 requires revising the existing airplane flight manual (AFM) by providing instructions to address dual loss of radio management panel (RMP) data synchronization. Since the FAA issued AD 2025-11-02, a software modification for the digital radio and audio integrating management system (DRAIMS) has been developed to address the unsafe condition. This proposed AD would continue to require the actions in AD 2025-11-02 and would require modification of the DRAIMS and add Model A321-271NY airplanes to the applicability. This proposed AD would also prohibit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; Airbus SAS Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2025-11-02, which applies to certain Airbus SAS Model A319-151N, -153N,
-171N, and -173N airplanes; A320-251N, -252N, -253N, -271N, -272N, and
-273N airplanes; A321-251N, -251NX, -252N, -252NX, -253N, -253NX, -
253NY, -271N, -271NX, -272N, and -272NX airplanes. AD 2025-11-02
requires revising the existing airplane flight manual (AFM) by
providing instructions to address dual loss of radio management panel
(RMP) data synchronization. Since the FAA issued AD 2025-11-02, a
software modification for the digital radio and audio integrating
management system (DRAIMS) has been developed to address the unsafe
condition. This proposed AD would continue to require the actions in AD
2025-11-02 and would require modification of the DRAIMS and add Model
A321-271NY airplanes to the applicability. This proposed AD would also
prohibit the installation of affected parts. The FAA is proposing this
AD to address the unsafe condition on these products.

Background
The FAA issued AD 2025-11-02, Amendment 39-23048 (90 FR 22199, May
27, 2025) (AD 2025-11-02), for Airbus SAS Model A319-151N, -153N, -
171N, and -173N airplanes; A320-251N, -252N, -253N, -271N, -272N, and -
273N airplanes; A321-251N, -251NX, -252N, -252NX, -253N, -253NX, -
253NY, -271N, -271NX, -272N, and -272NX airplanes having Airbus
modification 162344 or 168460, except those having Airbus modification
165670 installed in production. AD 2025-11-02 was prompted by an MCAI
originated by EASA, which is the Technical Agent for the Member States
of the European Union. EASA issued AD 2025-0037, dated February 12,
2025 (EASA AD 2025-0037), to correct an unsafe condition. EASA AD 2025-
0037 stated that occurrences of lost synchronization between RMPs were
reported, and that these occurrences led to loss of communications
means (RMP data synchronization and very high frequency (VHF)
communications) on the DRAIMS. Airbus issued instructions for regaining
communication and transponder means in certain failure conditions. EASA
AD 2025-0037 also stated the AD was considered an interim action and
that further AD action might follow.
AD 2025-11-02 requires revising the existing AFM by providing
instructions to address dual loss of RMP data synchronization. The FAA
issued AD 2025-11-02 to address loss of communications means (RMP data
synchronization and VHF communications) on the DRAIMS. This condition,
if not corrected, could result in total loss of radio communications,
including transponder functionality and standby navigation.
Actions Since AD 2025-11-02 Was Issued
Since the FAA issued AD 2025-11-02, EASA superseded EASA AD 2025-
0037 with EASA AD 2025-0118, dated February 12, 2025, which in turn was
revised by EASA AD 2025-0118R1, dated July 15, 2025 (EASA AD 2025-
0118R1) (also referred to as the MCAI), to correct an unsafe condition
for all Airbus SAS Model A319-151N, -153N, -171N, and -173N airplanes;
A320-251N, -252N, -253N, -271N, -272N, and -273N airplanes; A321-251N,
-251NX, -252N, -252NX, -253N, -253NX, -253NY, -271N, -271NX, -271NY, -
272N, and -272NX airplanes. The MCAI states that Airbus issued service
information to upgrade DRAIMS to the software L4.3 standard.
The preamble to AD 2025-11-02 explains that the FAA considers that
AD an interim action and that the FAA might consider further rulemaking
once the modification is developed, approved, and available. The DRAIMS
software L4.3 standard would address the unsafe condition and would
terminate the AFM revision required by AD 2025-11-02. Therefore, the
FAA has determined this modification should be required.
The FAA is proposing this AD to address the unsafe condition on
these products. You may examine the MCAI in the AD docket at
<a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2026-3481.
Material Incorporated by Reference Under 1 CFR Part 51
EASA AD 2025-0118R1 specifies procedures for revising the existing
AFM by providing instructions to address dual loss of RMP data
synchronization; and modifying the airplane by upgrading DRAIMS to the
software L4.3 standard, which includes upgrading the audio management
and RMP software and modifying the wiring at the 3rd occupant human-
machine interface input. EASA AD 2025-0118R1 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
These products have been approved by the civil aviation authority
of another country and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with this State of Design
Authority, that authority 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 retain all requirements of AD 2025-11-02.
This proposed AD would require accomplishing the actions specified in
EASA AD 2025-0118R1 described previously, except for any differences
identified as exceptions in the regulatory text of this proposed AD.
Compliance With AFM Revisions
EASA AD 2025-0118R1 requires operators to ``inform all flight
crews'' of revisions to the AFM, and thereafter to ``operate the
aeroplane accordingly.'' However, this proposed AD would not
specifically require those actions as those actions are already
required by FAA regulations. FAA regulations require operators furnish
to pilots any changes to the AFM (for example, 14 CFR 121.137), and to
ensure the pilots are familiar with the AFM (for example, 14 CFR
91.505). As with any other
[[Page 18794]]
flightcrew training requirement, training on the updated AFM content is
tracked by the operators and recorded in each pilot's training record,
which is available for the FAA to review. FAA regulations also require
pilots to follow the procedures in the existing AFM including all
updates. Section 91.9 requires that any person operating a civil
aircraft must comply with the operating limitations specified in the
AFM. Therefore, including a requirement in this proposed AD to operate
the airplane according to the revised AFM would be redundant and
unnecessary.
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 2025-0118R1 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2025-0118R1 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 2025-0118R1 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 2025-
0118R1. Material required by EASA AD 2025-0118R1 for compliance will be
available at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2026-3481 after the
FAA final rule is published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 544 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Retained actions from AD 2025-11-02...... 1 work-hour x $85 per hour $0 $85 $46,240
= $85.
New proposed action...................... Up to 7 work-hours x $85 774 1,369 744,736
per hour = $595.
----------------------------------------------------------------------------------------------------------------
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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

(l) 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 (m)(1) of this AD and email to:
<a href="/cdn-cgi/l/email-protection#43020e0c00032522226d242c35"><span class="__cf_email__" data-cfemail="febfb3b1bdbe989f9fd0999188">[email protected]</span></a>.
(i) Before using any approved AMOC, notify your appropriate
principal inspector, or lacking a principal inspector, the manager
of the responsible Flight Standards Office.
(ii) AMOCs approved previously for AD 2025-11-02 are approved as
AMOCs for the corresponding provisions of paragraph (g) of this AD.
(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 DOA-authorized signature.
(3) Required for Compliance (RC): Except as required by
paragraph (l)(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.
