SUPPLEMENTARY INFORMATION: SUMMARY: 1. The authority citation for part 130 continues to read as follows: ■ § 130.110 Final rule. Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would PO 00000 Frm 00025 Fmt 4700 Sfmt 4700 17717 apply to all Airbus SAS Model A350– 941 and –1041 airplanes. The NPRM published in the Federal Register on November 3, 2023 (88 FR 75520). The NPRM was prompted by AD 2023–0102, dated May 17, 2023, issued by EASA, which is the Technical Agent for the Member States of the European Union (EASA AD 2023–0102) (also referred to as the MCAI). The MCAI states there are reports of corrosion on lavatory floor fittings at various locations on Model A350 airplanes. In the NPRM, the FAA proposed to require repetitive general visual inspections of the affected parts, applicable corrective actions, and reporting of inspection results, as specified in EASA AD 2023–0102. The FAA is issuing this AD to address the corrosion, which could lead to lavatory module detachment, with consequent injury to cabin crew and passengers, and possibly result in reduced evacuation capacity from the airplane in case of an emergency. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–2141. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the cost to the public. Conclusion 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 reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Related Service Information Under 1 CFR Part 51 EASA AD 2023–0102 specifies procedures for repetitive general visual inspections for corrosion and other damage (including cracks, pitting, discoloration, and dents) of the affected lavatory floor fittings and, depending on findings, corrective actions including repair or replacement. EASA AD 2023– 0102 also requires reporting of the inspection results after each inspection.

Interim Action Costs of Compliance The FAA considers this AD an interim action. If final action is later identified, the FAA might consider further rulemaking then. The FAA estimates that this AD would affect 32 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 2 work-hours × $85 per hour = $170 .......................................................................................... $0 $170 $5,440 The FAA estimates the following costs to do any necessary on-condition actions 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 these on-condition actions: ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Cost per product 3 work-hours × $85 per hour = $255 ...................................................................................................................... $10 $265 The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected operators. khammond on DSKJM1Z7X2PROD with RULES 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 currently valid OMB Control Number. The OMB Control Number for this information collection is 2120–0056.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to all Airbus SAS Model 
A350-941 and -1041 airplanes. The NPRM published in the Federal 
Register on November 3, 2023 (88 FR 75520). The NPRM was prompted by AD 
2023-0102, dated May 17, 2023, issued by EASA, which is the Technical 
Agent for the Member States of the European Union (EASA AD 2023-0102) 
(also referred to as the MCAI). The MCAI states there are reports of 
corrosion on lavatory floor fittings at various locations on Model A350 
airplanes.
    In the NPRM, the FAA proposed to require repetitive general visual 
inspections of the affected parts, applicable corrective actions, and 
reporting of inspection results, as specified in EASA AD 2023-0102. The 
FAA is issuing this AD to address the corrosion, which could lead to 
lavatory module detachment, with consequent injury to cabin crew and 
passengers, and possibly result in reduced evacuation capacity from the 
airplane in case of an emergency.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-2141.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    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 reviewed the relevant data and determined 
that air safety requires adopting this AD as proposed. Accordingly, the 
FAA is issuing this AD to address the unsafe condition on this product. 
Except for minor editorial changes, this AD is adopted as proposed in 
the NPRM. None of the changes will increase the economic burden on any 
operator.

Related Service Information Under 1 CFR Part 51

    EASA AD 2023-0102 specifies procedures for repetitive general 
visual inspections for corrosion and other damage (including cracks, 
pitting, discoloration, and dents) of the affected lavatory floor 
fittings and, depending on findings, corrective actions including 
repair or replacement. EASA AD 2023-0102 also requires reporting of the 
inspection results after each inspection.

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.

Interim Action

    The FAA considers this AD 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 would affect 32 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------

----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition actions 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 these on-condition actions:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
3 work-hours x $85 per hour = $255....             $10             $265
------------------------------------------------------------------------

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some or all of the costs of 
this AD may be covered under warranty, thereby reducing the cost impact 
on affected operators.

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 currently 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

    This AD will not have federalism implications under Executive Order 
13132. This AD will 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 that this AD:

The Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 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.


Sec.  39.13  [Amended]

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

2024-03-03 Airbus SAS: Amendment 39-22672; Docket No. FAA-2023-2141; 
Project Identifier MCAI-2023-00689-T.

(a) Effective Date

    This airworthiness directive (AD) is effective April 16, 2024.

(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 25, Equipment/
Furnishings.

(e) Unsafe Condition

    This AD was prompted by reports of corrosion on lavatory floor 
fittings at various

[[Page 17719]]

locations on Model A350 airplanes. The unsafe condition, if not 
addressed, could lead to lavatory module detachment, with consequent 
injury to cabin crew and passengers, and possibly result in reduced 
evacuation capacity from the airplane in case of an emergency.

(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 
2023-0102, dated May 17, 2023 (EASA AD 2023-0102).

(h) Exceptions to EASA AD 2023-0102

    (1) Where EASA AD 2023-0102 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) This AD does not adopt the ``Remarks'' section of EASA AD 
2023-0102.
    (3) Paragraph (4) of EASA AD 2023-0102 specifies to report 
inspection results to Airbus within a certain compliance time. For 
this AD, report inspection results at the applicable time specified 
in paragraph (h)(3)(i) or (ii) of this AD.
    (i) For each inspection done on or after the effective date of 
this AD: Submit the report within 30 days after the inspection.
    (ii) For any inspection done before the effective date of this 
AD: Submit the report within 30 days after the effective date of 
this AD.
    (4) Where paragraph (2) of EASA AD 2023-0102 specifies ``any 
discrepancy, as defined in the SB, is detected,'' this AD requires 
replacing those words with ``any corrosion and other damage is 
detected.''

(i) No Requirement for Return of Parts

    Although the service information referenced in EASA AD 2023-0102 
specifies to return parts 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, 
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 International 
Validation Branch, send it to the attention of the person identified 
in paragraph (k) 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 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 (j)(2) of this AD, if any service information 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.
