Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Airbus SAS Model A350-941 and A350-1041 airplanes. This AD was

[[Page 67362]]

prompted by a determination that in the event of rapid decompression at 
a specific location of the airplane, possible deflections of the 
passenger floor cross beams may result in wiring damages, leading to 
potential system losses. This AD requires amending the operator's 
existing airplane flight manual (AFM) to update the landing performance 
database, as specified in a European Union Aviation Safety Agency 
(EASA) AD, which is incorporated by reference. The FAA is issuing this 
AD to address the unsafe condition on these products.

DATES: This AD is effective December 13, 2022.

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov under 
Docket No. FAA-2022-0817; or in person at Docket Operations between 9

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 certain Airbus A350-941 
and A350-1041 airplanes. The NPRM published in the Federal Register on 
July 12, 2022 (87 FR 41265). The NPRM was prompted by AD 2022-0054, 
dated March 23, 2022, issued by EASA, which is the Technical Agent for 
the Member States of the European Union (referred to after this as the 
MCAI). The MCAI states that in the event of rapid decompression at a 
specific location of the airplane, possible deflections of the 
passenger floor cross beams may result in wiring damages, leading to 
potential system losses.
    In the NPRM, the FAA proposed to require revising the operator's 
existing Airbus A350 AFM to update the landing performance database, as 
specified in EASA AD 2022-0054. The FAA is issuing 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-2022-0817.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from the Air Line Pilots Association and 
three individuals, who supported the NPRM without change. One 
individual did not support the NPRM but did not justify this position 
or request any changes to the NPRM.

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 the 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, considered the 
comments received, 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 2022-0054 specifies procedures for revising the operator's 
existing Airbus A350 AFM to update the landing performance database.
    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.

Costs of Compliance

    The FAA estimates that this AD would affect 30 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this 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

    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

[[Page 67363]]

responsibilities among the various levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) Will 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 Amendment

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

2022-20-13 Airbus SAS: Amendment 39-22197; Docket No. FAA-2022-0817; 
Project Identifier MCAI-2022-00369-T.

(a) Effective Date

    This airworthiness directive (AD) is effective December 13, 
2022.

(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 53, Fuselage.

(e) Unsafe Condition

    This AD was prompted by a determination that, in the event of 
rapid decompression at a specific location of the airplane, possible 
deflections of the passenger floor crossbeams may result in wiring 
damages, leading to potential system losses. The FAA is issuing this 
AD to address this unsafe condition, which could lead to an increase 
of the landing distance, exceeding the value provided in the current 
in-flight failure data file for landing, and potentially resulting 
in a runway excursion.

(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 
2022-0054, dated March 23, 2022 (EASA AD 2022-0054).

(h) Exceptions to EASA AD 2022-0054

    (1) Where EASA AD 2022-0054 refers to March 30, 2022 (the 
effective date of EASA AD 2022-0045, dated March 16, 2022), this AD 
requires using the effective date of this AD.
    (2) Where EASA AD 2022-0054 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.
    (3) Where the ``AFM Amendment'' paragraph of EASA AD 2022-0054 
specifies implementing an AFM [airplane flight manual] revision, for 
this AD, replace the text ''implement the AFM revision, as defined 
in this [EASA] AD'' with ``revise the operator's existing AFM to 
incorporate the aircraft performance database specified in the AFM 
revision, as defined in this [EASA] AD.''
    (4) The ``Remarks'' section of EASA AD 2022-0054 does not apply 
to this AD.

(i) Additional AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Large Aircraft Section, 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 Large Aircraft Section, International Validation Branch, send it 
to the attention of the person 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 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 (i)(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.
