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– 0058R1, dated April 16, 2024 (EASA AD 2024–0058R1) (also referred to as the MCAI), to correct an unsafe condition for all Airbus SAS Model A350–941 and A350–1041 airplanes. The MCAI states that during a maintenance inspection, thrust reverser and pylon thermal blankets were found damaged due to air leaking from the PCE. This condition, if not detected and corrected, could result in thermal blanket damage that, if combined with an independent event of engine fire, could lead to a temporary uncontrolled fire. E:\FR\FM\01JYP1.SGM 01JYP1 54394 Federal Register / Vol. 89, No. 126 / Monday, July 1, 2024 / Proposed Rules 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. 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–2024–1701. Proposed AD Requirements in This NPRM Related Material Under 1 CFR Part 51 EASA AD 2024–0058R1 specifies a repetitive air leak test of the PCE and reporting the results. If a leak is detected, EASA AD 2024–0058R1 specifies to replace the PCE and visually inspect the thrust reverser and pylon thermal blankets and replace if damaged. EASA AD 2024–0058R1 also requires performing an air leak test on any newly installed PCE. 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 ADDRESSES section. This proposed AD would require accomplishing the actions specified in EASA AD 2024–0058R1 described previously, except for any differences identified as exceptions in the regulatory text of this proposed AD. Explanation of Required Compliance Information 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 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 2024–0058R1 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2024– 0058R1 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 2024–0058R1 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 2024–0058R1. Service information required by EASA AD 2024–0058R1 for compliance will be available at regulations.gov under Docket No. FAA–2024–1701 after the FAA final rule is published. Interim Action The FAA considers that this proposed AD would be an interim action. If final action is later identified, the FAA might consider further rulemaking then. 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 3 work-hours × $85 per hour = $255 .......................................................................................... $0 $255 $8,160 ddrumheller on DSK120RN23PROD with PROPOSALS1 ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Up to 24 work-hours × $85 per hour = Up to $2,040 ................................................... Up to $18,844 .................... Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB Control Number. The OMB Control Number for this information collection is 2120–0056. Public reporting for this collection of information is estimated to take approximately 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. All responses to this collection of VerDate Sep<11>2014 16:45 Jun 28, 2024 Jkt 262001 information are mandatory. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to: Information Collection Clearance Officer, Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177–1524. 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 PO 00000 Frm 00026 Fmt 4702 Sfmt 4702 Cost per product Up to $20,884. 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 E:\FR\FM\01JYP1.SGM 01JYP1 Federal Register / Vol. 89, No. 126 / Monday, July 1, 2024 / Proposed Rules 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. 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 1.

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 A350-941 and A350-1041 airplanes. This 
proposed AD was prompted by a report the thrust reverser and pylon 
thermal blankets were found damaged due to air leaking from the pre-
cooler exchanger (PCE). This proposed AD would require repetitively 
testing the PCE for air leaks and reporting the results, and depending 
on findings, replacing the PCE and inspecting the thermal blankets for 
damage, as specified in a European Union Aviation Safety Agency (EASA) 
AD, which is proposed for incorporation by reference. The FAA is 
proposing this AD to address the unsafe condition on these products.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2024-0058R1, dated April 16, 2024 
(EASA AD 2024-0058R1) (also referred to as the MCAI), to correct an 
unsafe condition for all Airbus SAS Model A350-941 and A350-1041 
airplanes. The MCAI states that during a maintenance inspection, thrust 
reverser and pylon thermal blankets were found damaged due to air 
leaking from the PCE. This condition, if not detected and corrected, 
could result in thermal blanket damage that, if combined with an 
independent event of engine fire, could lead to a temporary 
uncontrolled fire.

[[Page 54394]]

    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-2024-1701.

Related Material Under 1 CFR Part 51

    EASA AD 2024-0058R1 specifies a repetitive air leak test of the PCE 
and reporting the results. If a leak is detected, EASA AD 2024-0058R1 
specifies to replace the PCE and visually inspect the thrust reverser 
and pylon thermal blankets and replace if damaged. EASA AD 2024-0058R1 
also requires performing an air leak test on any newly installed PCE.
    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 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 2024-0058R1 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 2024-0058R1 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2024-0058R1 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 2024-0058R1 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-
0058R1. Service information required by EASA AD 2024-0058R1 for 
compliance will be available at regulations.gov under Docket No. FAA-
2024-1701 after the FAA final rule is published.

Interim Action

    The FAA considers that this proposed AD would be an interim action. 
If final action is later identified, the FAA might consider further 
rulemaking then.

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:

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to a penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to take 
approximately 1 hour per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Send comments regarding this burden estimate 
or any other aspect of this collection of information, including 
suggestions for reducing this burden, to: Information Collection 
Clearance Officer, Federal Aviation Administration, 10101 Hillwood 
Parkway, Fort Worth, TX 76177-1524.

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

[[Page 54395]]

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.

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-2024-1701; Project Identifier MCAI-2024-
00153-T.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by August 15, 2024.

(b) Affected ADs

    None.

(c) Applicability

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

(d) Subject

    Air Transport Association (ATA) of America Code 36, Pneumatic.

(e) Unsafe Condition

    This AD was prompted by a report the thrust reverser and pylon 
thermal blankets were found damaged due to air leaking from the pre-
cooler exchanger (PCE). The FAA is issuing this AD to address the 
PCE leaking air. The unsafe condition, if not addressed, could 
result in thermal blanket damage that, if combined with an 
independent event of engine fire, could lead to a temporary 
uncontrolled fire.

(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 
2024-0058R1, dated April 16, 2024 (EASA AD 2024-0058R1).

(h) Exceptions to EASA AD 2024-0058R1

    (1) Where EASA AD 2024-0058R1 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) Where paragraph (4) of EASA AD 2024-0058R1 specifies ``if 
any discrepancy is detected, before next flight, contact Airbus for 
approved instructions and accomplish those instructions 
accordingly,'' this AD requires replacing that text with ``if any 
discrepancy is detected, the discrepancy must be repaired before 
further flight using a method approved by the Manager, International 
Validation 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) Paragraph (6) of EASA AD 2024-0058R1 specifies to report air 
leak test results to Airbus within a certain compliance time. For 
this AD, report test results at the applicable time specified in 
paragraph (h)(3)(i) or (ii) of this AD.
    (i) If the test was done on or after the effective date of this 
AD: Submit the report within 30 days after the test.
    (ii) If the test was done before the effective date of this AD: 
Submit the report within 30 days after the effective date of this 
AD.
    (4) This AD does not adopt the ``Remarks'' section of EASA AD 
2024-0058R1.

(i) Additional AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Validation 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 
International Validation Branch, mail it to the address identified 
in paragraph (j) of this AD. Information may be emailed 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, International 
Validation Branch, FAA; or EASA; or Airbus SAS's EASA DOA. If 
approved by the DOA, the approval must include the DOA-authorized 
signature.
    (3) Required for Compliance (RC): Except as required by 
paragraph (i)(2) of this AD, if any material referenced in EASA AD 
2024-0058R1 contains paragraphs that are labeled as RC, the 
instructions in RC paragraphs, including subparagraphs under an RC 
paragraph, must be done to comply with this AD; any paragraphs, 
including subparagraphs under those paragraphs, that are not 
identified as RC are recommended. The instructions in paragraphs, 
including subparagraphs under those paragraphs, 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 instructions identified as RC can 
be done and the airplane can be put back in an airworthy condition. 
Any substitutions or changes to instructions identified as RC 
require approval of an AMOC.
