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 2023–0052, dated March 14, 2023 (EASA AD 2023– 0052) (also referred to as the MCAI), to correct an unsafe condition for certain Airbus A330–201, A330–202, A330– 203, A330–223, A330–223F, A330–243, PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 A330–243F, A330–301, A330–302, A330–303, A330–321, A330–322, A330– 323, A330–341, A330–342, A330–343, A330–743L, A330–841, and A330–941 airplanes. Model A330–743L airplanes are not certificated by the FAA and are not included on the U.S. type certificate data sheet; this proposed AD therefore does not include those airplanes in the applicability. The MCAI states that a determination has been made that the differential pressure test across Rib 3, part of the production ground test procedure used to confirm inner fuel tank integrity, was not properly accomplished on airplanes delivered before July 2021. The FAA is issuing this AD to address lack of inner fuel tank integrity that, in the case of an uncontained engine rotor failure and subsequent fuel tank puncture, could lead to insufficient fuel available to ensure continued safe flight and landing. 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–2023–1498. Related Service Information Under 1 CFR Part 51 EASA AD 2023–0052 specifies procedures for performing a leak test of the inner fuel tanks for discrepancies (i.e., leaks; a leak test is failed if, during a secondary recording of capacitance values, the aft inner tank probe FIN 25QT1(FIN 25QT2) and FIN 123QT1(FIN 123QT2) values reduce by 2pF when compared with those in the initial recording) and, depending on findings, accomplishing applicable corrective action. Corrective actions include performing the applicable fault isolation and rectification. Airbus Service Bulletin A330–28– 3141, dated December 16, 2022, specifies serial numbers of affected airplanes. 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. 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 and service information referenced above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is E:\FR\FM\20JYP1.SGM 20JYP1 Federal Register / Vol. 88, No. 138 / Thursday, July 20, 2023 / Proposed Rules 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 2023–0052 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 2023–0052 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2023–0052 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 2023–0052 does not mean that operators need comply only with that section. For example, where the AD 46701 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 2023–0052. Service information required by EASA AD 2023–0052 for compliance will be available at regulations.gov under Docket No. FAA–2023–1498 after the FAA final rule is published. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 128 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 4 work-hours × $85 per hour = $340 .......................................................................................... $0 $340 $43,520 The FAA has received no definitive data on which to base the cost estimates for the on-condition actions specified in 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. lotter on DSK11XQN23PROD with PROPOSALS1 Regulatory Findings 16:16 Jul 19, 2023 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. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 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. VerDate Sep<11>2014 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. Jkt 259001 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive: ■ Airbus SAS: Docket No. FAA–2023–1498; Project Identifier MCAI–2023–00459–T.

Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Airbus SAS Model A330-200, A330-200 Freighter, A330-300, 
A330-800, and A330-900 series airplanes. This proposed AD was prompted 
by a determination that part of a certain production ground test 
procedure used to confirm inner fuel tank integrity was not 
accomplished properly on certain airplanes. This proposed AD would 
require a fuel tank leak test and, depending on findings, 
accomplishment of applicable corrective action, as specified in a 
European Union Aviation Safety Agency (EASA) AD, which is proposed for 
incorporation by reference (IBR). The FAA is proposing this AD to

[[Page 46700]]

address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION: 

Comments Invited

    The FAA invites you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under ADDRESSES. Include ``Docket No. FAA-2023-1498; Project Identifier 
MCAI-2023-00459-T'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the proposal, explain the 
reason for any recommended change, and include supporting data. The FAA 
will consider all comments received by the closing date and may amend 
this proposal because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
regulations.gov, including any personal information you provide. The 
agency will also post a report summarizing each substantive verbal 
contact received about this NPRM.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. 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 Tim 
Dowling, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, 
Westbury, NY 11590; phone: 206-231-3667; email: 
[email protected]. 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 2023-0052, dated March 14, 2023 
(EASA AD 2023-0052) (also referred to as the MCAI), to correct an 
unsafe condition for certain Airbus A330-201, A330-202, A330-203, A330-
223, A330-223F, A330-243, A330-243F, A330-301, A330-302, A330-303, 
A330-321, A330-322, A330-323, A330-341, A330-342, A330-343, A330-743L, 
A330-841, and A330-941 airplanes. Model A330-743L airplanes are not 
certificated by the FAA and are not included on the U.S. type 
certificate data sheet; this proposed AD therefore does not include 
those airplanes in the applicability. The MCAI states that a 
determination has been made that the differential pressure test across 
Rib 3, part of the production ground test procedure used to confirm 
inner fuel tank integrity, was not properly accomplished on airplanes 
delivered before July 2021. The FAA is issuing this AD to address lack 
of inner fuel tank integrity that, in the case of an uncontained engine 
rotor failure and subsequent fuel tank puncture, could lead to 
insufficient fuel available to ensure continued safe flight and 
landing.
    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-2023-1498.

Related Service Information Under 1 CFR Part 51

    EASA AD 2023-0052 specifies procedures for performing a leak test 
of the inner fuel tanks for discrepancies (i.e., leaks; a leak test is 
failed if, during a secondary recording of capacitance values, the aft 
inner tank probe FIN 25QT1(FIN 25QT2) and FIN 123QT1(FIN 123QT2) values 
reduce by 2pF when compared with those in the initial recording) and, 
depending on findings, accomplishing applicable corrective action. 
Corrective actions include performing the applicable fault isolation 
and rectification.
    Airbus Service Bulletin A330-28-3141, dated December 16, 2022, 
specifies serial numbers of affected airplanes.
    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.

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 and 
service information referenced above. The FAA is issuing this NPRM 
after determining that the unsafe condition described previously is

[[Page 46701]]

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 2023-0052 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 2023-0052 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2023-0052 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 2023-0052 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 2023-
0052. Service information required by EASA AD 2023-0052 for compliance 
will be available at regulations.gov under Docket No. FAA-2023-1498 
after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 128 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.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
4 work-hours x $85 per hour = $340...........................              $0             $340          $43,520
----------------------------------------------------------------------------------------------------------------

    The FAA has received no definitive data on which to base the cost 
estimates for the on-condition actions specified in 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.
