Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2022-08-
04, which applied to all Airbus SAS Model A300 series airplanes. AD 
2022-08-04 required revising the existing maintenance or inspection 
program, as applicable, to incorporate new or more restrictive 
airworthiness limitations. Since the FAA issued AD 2022-08-04, the FAA 
has determined new or more restrictive airworthiness limitations are 
necessary. This AD continues to require the actions of AD 2022-08-04, 
and requires new or more restrictive airworthiness limitations, 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 January 17, 2024.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of January 17, 
2024.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of June 
16, 2022 (87 FR 29037, May 12, 2022).

agency will also post a report summarizing each substantive verbal 
contact received about this final rule.

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 AD 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 AD, 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 AD. Submissions containing CBI should be sent to Dan 
Rodina, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, 
Westbury, NY 11590; telephone 206-231-3225; 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

    The FAA issued AD 2022-08-04, Amendment 39-22007 (87 FR 29037, May 
12, 2022) (AD 2022-08-04), for all Airbus SAS Model A300 series 
airplanes. AD 2022-08-04 was prompted by an MCAI originated by EASA, 
which is the Technical Agent for the Member States of the European 
Union. EASA issued AD 2021-0134, dated June 1, 2021 (EASA AD 2021-
0134), to correct an unsafe condition.
    AD 2022-08-04 required revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations described in Airbus A300

[[Page 18]]

Airworthiness Limitations Section (ALS) Part 2 Damage Tolerant 
Airworthiness Limitation Items (DT-ALI) Revision 03, Variation 3.2 
(Variation 3.2). The FAA issued AD 2022-08-04 to address possible 
reduced structural integrity of the airplane.

Actions Since AD 2022-08-04 Was Issued

    Since the FAA issued AD 2022-08-04, EASA superseded EASA AD 2021-
0134 and issued EASA AD 2023-0104, dated May 24, 2023 (EASA AD 2023-
0104) (also referred to as the MCAI), to correct an unsafe condition 
for all Airbus SAS Model A300 series airplanes. The FAA has removed 
Airbus SAS Model A300 B2-1A, B2-1C, B2K-3C, and B2-203 airplanes from 
the FAA type certificate. Therefore, this AD does not include those 
airplanes in the applicability.
    The MCAI states that since EASA AD 2021-0134 was issued, Airbus 
published Airbus A300 ALS Part 2 DT-ALI Revision 03, Variation 3.4 
(Variation 3.4), which supersedes Variation 3.2. Variation 3.4, as 
defined in EASA AD 2023-0104, contains new and more restrictive tasks 
and introduces Maintenance Program Publication Triggers (MPPT), 
reflecting the limit of validity (LOV) of the engineering data that 
supports the structural maintenance program. Therefore, EASA AD 2023-
0104 takes over the requirements of EASA AD 2021-0134 and requires 
accomplishment of the actions and compliance with the new MPPT 
specified in Variation 3.4.
    The MCAI also stated it had previously issued AD 2017-0207, dated 
October 12, 2017 (EASA AD 2017-0207); AD 2020-0110R1, dated May 27, 
2020 (EASA AD 2020-0110R1); AD 2021-0134; and AD 2021-0181, dated July 
30, 2021 (EASA AD 2021-0181); requiring the actions described in Airbus 
A300 Airbus A300 ALS Part 2 DT-ALI Revision 03, Variation 3.1, 
Variation 3.2, and Variation 3.3, respectively. EASA AD 2017-0207 
corresponds to FAA AD 2018-19-17, Amendment 39-19417 (83 FR 48207, 
September 24, 2018). EASA AD 2020-0110R1 corresponds to certain actions 
in FAA AD 2020-23-11, Amendment 39-21327 (85 FR 75838, November 27, 
2020). EASA AD 2021-0181 corresponds to FAA AD 2022-05-06, Amendment 
39-21957 (87 FR 10956, February 28, 2022). After those EASA ADs were 
issued, Airbus published Variation 3.4, as defined in EASA AD 2023-
0104. The MCAI states that it does not supersede EASA ADs 2017-0207, 
2020-0110R1, and 2021-0181. However, the MCAI does affect EASA AD 2017-
0207 and specifies that where it requires a task (limitation) that is 
required by EASA AD 2017-0207 (which corresponds to FAA AD 2018-19-17), 
the instructions of Variation 3.4 invalidate (terminate) the 
instructions of Airbus A300 Airbus A300 ALS Part 2 DT-ALI Revision 03. 
Therefore, accomplishing the actions required by paragraph (j) of this 
AD terminates the corresponding requirements of AD 2018-19-17 for the 
tasks identified in the service information referenced in EASA AD 2023-
0104 only. This AD also replaces the LOVs specified in paragraph 1.3 of 
Airbus A300 Airworthiness Limitations Section (ALS), Part 2--Damage 
Tolerant Airworthiness Limitation Items (DT-ALI), Revision 03, dated 
August 28, 2017, as required by FAA AD 2018-19-17.
    The FAA is issuing this AD to address possible reduced structural 
integrity of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-2243.

Related Service Information Under 1 CFR Part 51

    EASA AD 2023-0104 specifies procedures for new or more restrictive 
airworthiness limitations, which includes updated airplane LOV language 
and MPPTs.
    This AD also requires EASA AD 2021-0134, dated June 1, 2021, which 
the Director of the Federal Register approved for incorporation by 
reference as of June 16, 2022 (87 FR 29037, May 12, 2022).
    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 AD after determining that the 
unsafe condition described previously is likely to exist or develop on 
other products of the same type design.

Requirements of This AD

    This AD requires revising the existing maintenance or inspection 
program, as applicable, to incorporate new or more restrictive 
airworthiness limitations, which are specified in EASA AD 2023-0104 
described previously, as incorporated by reference.
    This AD requires revisions to certain operator maintenance 
documents to include new actions (e.g., inspections). Compliance with 
these actions is required by 14 CFR 91.403(c). For airplanes that have 
been previously modified, altered, or repaired in the areas addressed 
by this AD, the operator may not be able to accomplish the actions 
described in the revisions. In this situation, to comply with 14 CFR 
91.403(c), the operator must request approval for an alternative method 
of compliance (AMOC) according to paragraph (n)(1) of this 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 
incorporation by reference of EASA AD 2021-0134 is retained and EASA AD 
2023-0104 is incorporated by reference in this AD. This AD requires 
compliance with EASA AD 2021-0134 and EASA AD 2023-0104 in their 
entirety through that incorporation, except for any differences 
identified as exceptions in the regulatory text of this AD. Using 
common terms that are the same as the heading of a particular section 
in EASA AD 2021-0134 or EASA AD 2023-0104 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 2021-
0134 or EASA AD 2023-0104. Service information required by EASA AD 
2021-0134 and EASA AD 2023-0104 for compliance will be available at 
regulations.gov under Docket No. FAA-2023-2243 after this AD is 
published.

Airworthiness Limitation ADs Using the New Process

    The FAA's process of incorporating by reference MCAI ADs as the 
primary source of information for compliance with corresponding FAA ADs 
has been limited to certain MCAI ADs (primarily those with service 
bulletins as the primary source of information for accomplishing the 
actions required by the FAA AD). However, the FAA is now

[[Page 19]]

expanding the process to include MCAI ADs that require a change to 
airworthiness limitation documents, such as airworthiness limitation 
sections.
    For these ADs that incorporate by reference an MCAI AD that changes 
airworthiness limitations, the FAA requirements are unchanged. 
Operators must revise the existing maintenance or inspection program, 
as applicable, to incorporate the information specified in the new 
airworthiness limitation document. The airworthiness limitations must 
be followed according to 14 CFR 91.403(c) and 91.409(e).
    The previous format of the airworthiness limitation ADs included a 
paragraph that specified that no alternative actions (e.g., 
inspections) or intervals may be used unless the actions and intervals 
are approved as an AMOC in accordance with the procedures specified in 
the AMOCs paragraph under ``Additional AD Provisions.'' This new format 
includes a ``New Provisions for Alternative Actions and Intervals'' 
paragraph that does not specifically refer to AMOCs, but operators may 
still request an AMOC to use an alternative action or interval.

FAA's Justification and Determination of the Effective Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and 
comment procedures for rules when the agency, for ``good cause,'' finds 
that those procedures are ``impracticable, unnecessary, or contrary to 
the public interest.'' Under this section, an agency, upon finding good 
cause, may issue a final rule without providing notice and seeking 
comment prior to issuance. Further, section 553(d) of the APA 
authorizes agencies to make rules effective in less than thirty days, 
upon a finding of good cause.
    There are currently no domestic operators of these products. 
Accordingly, notice and opportunity for prior public comment are 
unnecessary, pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the 
forgoing reason(s), the FAA finds that good cause exists pursuant to 5 
U.S.C. 553(d) for making this amendment effective in less than 30 days.

Regulatory Flexibility Act (RFA)

    The requirements of the RFA do not apply when an agency finds good 
cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and 
comment. Because the FAA has determined that it has good cause to adopt 
this rule without notice and comment, RFA analysis is not required.

Costs of Compliance

    Currently, there are no affected U.S.-registered airplanes. For any 
affected airplane that may be imported and placed on the U.S. Register 
in the future, the FAA provides the following cost estimates to comply 
with this AD:
    The FAA estimates the total cost per operator for the retained 
actions from AD 2022-08-04 to be $7,650 (90 work-hours x $85 per work-
hour).
    The FAA has determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although the agency recognizes that this number may vary from operator 
to operator. Since operators incorporate maintenance or inspection 
program changes for their affected fleet(s), the FAA has determined 
that a per-operator estimate is more accurate than a per-airplane 
estimate.
    The FAA estimates the total cost per operator for the new action to 
be $7,650 (90 work-hours x $85 per work-hour).

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:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866, and
    (2) Will not affect intrastate aviation in Alaska.

(h) Retained Exceptions to EASA AD 2021-0134, With No Changes

    This paragraph restates the exceptions specified in paragraph 
(h) of AD 2022-08-04, with no changes.
    (1) Where EASA AD 2021-0134 refers to its effective date, this 
AD requires using June 16, 2022 (the effective date of AD 2022-08-
04).
    (2) Where paragraph (1) of EASA AD 2021-0134 specifies ``This AD 
invalidates the LOV [limit of validity] as specified in Airbus A300 
ALS Part 2 Revision 03 [EASA AD 2017-0207],'' this AD replaces the 
LOVs specified in paragraph 1.3 of Airbus A300 Airworthiness 
Limitations Section (ALS), Part 2--Damage Tolerant Airworthiness 
Limitation Items (DT-ALI), Revision 03, dated August 28, 2017, as 
required by FAA AD 2018-19-17.
    (3) Paragraph (2) of EASA AD 2021-0134 specifies revising ``the 
approved AMP'' within 12 months after its effective date, but this 
AD requires revising the existing maintenance or inspection program, 
as applicable, within 90 days after June 16, 2022 (the effective 
date of AD 2022-08-04).
    (4) The ``Remarks'' section of EASA AD 2021-0134 does not apply 
to this AD.

(i) Retained Restrictions on Alternative Actions and Intervals With a 
New Exception

    This paragraph restates the requirements of paragraph (i) of AD 
2022-08-04, with a new exception. Except as required by paragraph 
(j) of this AD, after the existing maintenance or inspection program 
has been revised as required by paragraph (g) of this AD, no 
alternative actions (e.g., inspections) or intervals are allowed 
unless they are approved as specified in the provisions of the 
``Ref. Publications'' section of EASA AD 2021-0134.

(j) New Revision of the Existing Maintenance or Inspection Program

    Except as specified in paragraph (k) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with, EASA AD 2023-0104, dated May 24, 2023 (EASA AD 
2023-0104). Accomplishing the revision of the existing maintenance 
or inspection program required by this paragraph terminates the 
requirements of paragraph (g) of this AD.

(k) Exceptions to EASA AD 2023-0104

    (1) This AD does not adopt the requirements specified in 
paragraphs (1), (2), and (3) of EASA AD 2023-0104.
    (2) Where paragraph (4) of EASA AD 2023-0104 specifies ``Within 
12 months after the effective date of this AD, revise the AMP,'' 
this AD requires replacing those words with ``Within 90 days after 
the effective date of this AD, revise the existing maintenance or 
inspection program, as applicable.''
    (3) The initial compliance time for doing the tasks specified in 
paragraph (4) of EASA AD 2023-0104 is at the associated thresholds 
as incorporated by the requirements of paragraph (4) of EASA AD 
2023-0104, or within 90 days after the effective date of this AD, 
whichever occurs later.
    (4) This AD does not adopt the provisions specified in paragraph 
(5) of EASA AD 2023-0104.
    (5) This AD does not adopt the ``Remarks'' section of EASA AD 
2023-0104.

(l) Replacement of LOVs and Terminating Action for AD 2018-19-17

    (1) Accomplishing the actions required by paragraph (j) of this 
AD replaces the LOVs specified in paragraph 1.3 of Airbus A300 
Airworthiness Limitations Section (ALS), Part 2-Damage Tolerant 
Airworthiness Limitation Items (DT-ALI), Revision 03, dated August 
28, 2017, as required by AD 2018-19-17.
    (2) Accomplishing the actions required by paragraph (j) of this 
AD terminates the corresponding requirements of AD 2018-19-17 for 
the tasks identified in the service information referenced in AD 
2023-0104 only.

(m) New Provisions for Alternative Actions and Intervals

    After the existing maintenance or inspection program has been 
revised as required by paragraph (j) of this AD, no alternative 
actions (e.g., inspections) and intervals are allowed unless they 
are approved as specified in the provisions of the ``Ref. 
Publications'' section of EASA AD 2023-0104.

(n) 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 (o) 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 (n)(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
