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 James Clary, Aviation Safety Engineer, FAA, 2200 South 216th St., Des Moines, WA 98198; telephone: 817–222–5138; email: james.clary@ 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 2024–0190, dated October 10, 2024; corrected October 11, 2024 (EASA AD 2024–0190) (also referred to as the MCAI), to correct an unsafe condition for all Airbus SAS Model A350–941, A350–1041, A380– 841, and A380–842 airplanes. The MCAI states the applicable AFM was providing an incorrect value for maximum cumulative taxi time in freezing fog conditions, which could lead to multiple engine surges in a critical flight phase and possibly result in loss of control of the airplane. The FAA is proposing this AD to address the unsafe condition on these products. E:\FR\FM\26MRP1.SGM 26MRP1 13708 Federal Register / Vol. 90, No. 57 / Wednesday, March 26, 2025 / Proposed Rules You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2025–0475. Material Incorporated by Reference Under 1 CFR Part 51 EASA AD 2024–0190 specifies procedures for an AFM amendment to correct the maximum cumulative taxi time in freezing fog conditions. 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 2024–0190 described previously, except for any differences identified as exceptions in the regulatory text of this proposed AD and except as discussed under ‘‘Differences Between This NPRM and the MCAI.’’ Compliance With AFM Revisions EASA AD 2024–0190 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 that 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 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. 14 CFR 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 2024–0190 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2024–0190 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 2024–0190 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 2024–0190. Material required by EASA AD 2024– 0190 for compliance will be available at regulations.gov under Docket No. FAA– 2025–0475 after the FAA final rule is published. Differences Between This NPRM and the MCAI This proposed AD does not include the Airbus S.A.S. Model A380–841 and –842 airplanes that are specified in the MCAI. Instead, the FAA has added the MCAI to the required airworthiness actions list (RAAL) for the Model A380 airplanes. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 32 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 1 work-hour × $85 per hour = $85 .............................................................................................. $0 $85 $2,720 khammond on DSK9W7S144PROD with PROPOSALS 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 VerDate Sep<11>2014 16:00 Mar 25, 2025 Jkt 265001 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 PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 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.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2024-0190, dated October 10, 2024; 
corrected October 11, 2024 (EASA AD 2024-0190) (also referred to as the 
MCAI), to correct an unsafe condition for all Airbus SAS Model A350-
941, A350-1041, A380-841, and A380-842 airplanes. The MCAI states the 
applicable AFM was providing an incorrect value for maximum cumulative 
taxi time in freezing fog conditions, which could lead to multiple 
engine surges in a critical flight phase and possibly result in loss of 
control of the airplane.
    The FAA is proposing this AD to address the unsafe condition on 
these products.

[[Page 13708]]

    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2025-0475.

Material Incorporated by Reference Under 1 CFR Part 51

    EASA AD 2024-0190 specifies procedures for an AFM amendment to 
correct the maximum cumulative taxi time in freezing fog conditions. 
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 2024-0190 described previously, except for any differences 
identified as exceptions in the regulatory text of this proposed AD and 
except as discussed under ``Differences Between This NPRM and the 
MCAI.''

Compliance With AFM Revisions

    EASA AD 2024-0190 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 that 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 
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. 14 CFR 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 2024-0190 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2024-0190 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 2024-0190 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-
0190. Material required by EASA AD 2024-0190 for compliance will be 
available at regulations.gov under Docket No. FAA-2025-0475 after the 
FAA final rule is published.

Differences Between This NPRM and the MCAI

    This proposed AD does not include the Airbus S.A.S. Model A380-841 
and -842 airplanes that are specified in the MCAI. Instead, the FAA has 
added the MCAI to the required airworthiness actions list (RAAL) for 
the Model A380 airplanes.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 32 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

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, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13   [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

Airbus SAS: Docket No. FAA-2025-0475; Project Identifier MCAI-2024-
00600-T.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by May 12, 2025.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Airbus SAS Model A350-941 and -1041 
airplanes, certificated in any category.

(d) Subject

    Air Transport Association (ATA) of America Code 71, Powerplant.

(e) Unsafe Condition

    This AD was prompted by a determination that the applicable 
aircraft flight manual (AFM) was providing an incorrect value for 
maximum cumulative taxi time in freezing fog conditions. The FAA is 
issuing this AD to address the incorrect maximum cumulative taxi 
time in freezing fog conditions. The unsafe condition, if not 
addressed, could lead to multiple engine surges in a critical flight 
phase and possibly result in loss of control of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with, European Union Aviation Safety Agency (EASA) AD 
2024-0190, dated October 10, 2024; corrected October 11, 2024 (EASA 
AD 2024-0190).

(h) Exceptions to EASA AD 2024-0190

    (1) Where EASA AD 2024-0190 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) Where paragraph (1) of EASA AD 2024-0190 specifies 
``implement the AFM DU revision,'' this AD requires replacing that 
text with ``revise the applicable existing AFM by incorporating the 
applicable AFM DU revision.''
    (3) Where paragraph (1) of EASA AD 2024-0190 specifies to 
``inform all flight crews, and thereafter, operate the aeroplane 
accordingly,'' this AD does not require those actions as those 
actions are already required by existing FAA operating regulations 
(see 14 CFR 91.9, 14 CFR 91.505, and 14 CFR 121.137).
    (4) This AD does not adopt the ``Remarks'' section of EASA AD 
2024-0190.

(i) 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

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 (j) of this AD and email to: 
[email protected]. 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 DOA-authorized signature.
