SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2023-13-10, Amendment 39-22495 (88 FR 
50005, August 1, 2023) (AD 2023-13-10), and AD 2024-04-03, Amendment 
39-22682 (89 FR 18769, March 15, 2024) (AD 2024-04-03). AD 2023-13-10 
and AD 2024-04-03 applied to certain Airbus SAS Model A318, A319, A320, 
and A321 series airplanes. AD 2023-13-10 required revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations. AD 2024-04-03 required 
revising the existing maintenance or inspection program, as applicable, 
to incorporate additional new or more restrictive airworthiness 
limitations and terminated certain requirements of AD 2023-13-10. The 
FAA issued AD 2023-13-10 and AD 2024-04-03 to address fatigue cracking, 
accidental damage, or corrosion in principal structural elements, which 
could result in reduced structural integrity of the airplane.
    The NPRM published in the Federal Register on September 20, 2024 
(89 FR

[[Page 9596]]

77045). The NPRM was prompted by AD 2024-0031, dated January 31, 2024; 
corrected February 1, 2024, issued by EASA, which is the Technical 
Agent for the Member States of the European Union (EASA AD 2024-0031) 
(also referred to as the MCAI). The MCAI states that new or more 
restrictive airworthiness limitations have been developed.
    In the NPRM, the FAA proposed to continue to require all 
requirements of AD 2024-04-03 and certain requirements of AD 2023-13-
10. The FAA also proposed to require revising the existing maintenance 
or inspection program, as applicable, to incorporate additional new or 
more restrictive airworthiness limitations, as specified in EASA AD 
2024-0031. The FAA is issuing this AD to address fatigue cracking, 
accidental damage, or corrosion in principal structural elements, which 
could result in reduced structural integrity of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-2145.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from two commenters, Delta Air Lines 
(Delta) and United Airlines (United). The following presents the 
comments received on the NPRM and the FAA's response to each comment.

Request To Except Certain Tasks

    Delta requested that an exception be added to paragraph (o) of the 
proposed AD to exclude tasks in section 4 of Airbus A318/A319/A320/A321 
Airworthiness Limitations Section (ALS) Part 2 (ALS Part 2). In 
correspondence between Delta and Airbus, Delta noted certain ALS Part 2 
tasks did not include associated maintenance planning document (MPD) or 
airplane maintenance manual (AMM) references. Delta stated that Airbus 
replied that those tasks are in Section 4 of ALS Part 2 and are part of 
the Maintenance Program Publication Trigger (MPPT), and that the 
contents of section 4 have been excluded from the MPD because the 
requirements of section 4 are not applicable to any operator today. 
Airbus also stated that if the tasks in that section become applicable, 
they would be transferred to section 3 of that document.
    The FAA agrees with adding an exception to paragraph (o) of this AD 
to exclude incorporation of Section 4, ``Damage Tolerant--Airworthiness 
Limitations Items--tasks beyond MPPT,'' of ALS Part 2 and has revised 
this AD accordingly. Tasks listed under the MPPT are a placeholder with 
no maintenance instructions. According to the binding schedule between 
Airbus and the FAA, maintenance instructions for these tasks must be 
provided by Airbus prior to reaching the threshold of such task. The 
FAA acknowledges when such tasks become applicable, Airbus moves them 
into Section 3 of ALS Part 2 as new requirements. Therefore, it is not 
necessary to incorporate Section 4 of ALS Part 2 into the applicable 
existing maintenance or inspection program.

Request To Add a Paragraph Specifying AD 2017-22-03 Has Been Superseded

    Delta requested that a paragraph be added to the proposed AD 
stating AD 2017-22-03, Amendment 39-19083 (82 FR 49091, October 24, 
2017) (AD 2017-22-03), has been superseded and is historical in 
reference. Delta noted AD 2017-22-03 required incorporation of ALS Part 
1, Revision 02, and ALS Part 2, Revision 02. Delta also noted paragraph 
(j) of AD 2017-22-03 specified that incorporation of ALS Part 1, 
Revision 04, into the applicable maintenance or inspection program is a 
method of compliance for incorporation of ALS Part 1, Revision 02, and 
that this requirement was later terminated by AD 2018-17-19, Amendment 
39-19373 (83 FR 44460, August 31, 2018) (AD 2018-17-19), which mandated 
ALS Part 1, Revision 05. Delta stated AD 2018-17-19 was subsequently 
superseded by AD 2019-19-15, Amendment 39-19751 (84 FR 54480, October 
10, 2019) (AD 2019-19-15). Delta further stated while AD 2018-17-19 is 
noted as ``Historical'' in the FAA Dynamic Regulatory System (DRS), AD 
2017-22-03 shows as ``Current'' in DRS.
    The FAA agrees that all the requirements of AD 2017-22-03 have been 
terminated by previous ADs. After AD 2017-22-03 was issued, subsequent 
ALS Part 1 revisions and ALS Part 2 revisions were separated into 
different AD actions. The FAA acknowledges the requirements to 
incorporate ALS Part 1, Revision 02, were terminated by AD 2018-17-19, 
which was later terminated by AD 2019-19-15. The FAA subsequently 
issued AD 2020-21-11, Amendment 39-21284 (85 FR 65674, October 16, 
2020), to supersede AD 2018-17-19 and AD 2019-19-15. AD 2022-22-10, 
Amendment 39-22225 (87 FR 72374, November 25, 2022), is the AD that 
requires incorporation of ALS Part 1, Revision 08.
    The remaining requirements of AD 2017-22-03 pertaining to 
incorporation of ALS Part 2, Revision 02, were terminated by AD 2018-
25-02, Amendment 39-19513 (83 FR 62690, December 6, 2018) (AD 2018-25-
02), which was later terminated by AD 2019-23-01, Amendment 39-19794 
(84 FR 66579, December 5, 2019) (AD 2019-23-01). The FAA subsequently 
issued AD 2020-20-05, Amendment 39-21261 (85 FR 65197, October 15, 
2020) (AD 2020-20-05), to supersede AD 2018-25-02 and AD 2019-23-01. 
The FAA then issued AD 2023-13-10 (which requires incorporation of ALS 
Part 2, Revision 09) to supersede AD 2020-20-05. This AD requires 
incorporation of ALS Part 2, Revision 10, Issue 02, as specified in 
EASA AD 2024-0031.
    The FAA recognizes that AD 2017-22-03 should have been superseded 
with issuance of AD 2020-20-05 and AD 2020-21-11. Therefore, the FAA 
has revised this AD to supersede AD 2017-22-03. Note the requirements 
of AD 2017-22-03 are not restated in this AD because those requirements 
were terminated by previous ADs that mandated incorporation of later 
revisions to ALS Part 1 and ALS Part 2. After the effective date of 
this AD, the FAA will recategorize AD 2017-22-03 as historical in the 
DRS.

Request To Extend Compliance Time for Certain Tasks

    United requested that the proposed AD be revised to allow 
extensions provided in Airbus Statement of Compliance (ASAC) when it 
supports extensions to compliance times of specified ALS Part 2 tasks 
as an alternative method of compliance (AMOC). United noted that Airbus 
does not have the authority for Design Organization Approval (DOA) 
signatures on ASACs. United stated Airbus analysis and technical 
substantiations justify that the extensions in an ASAC provide an 
acceptable level of safety to ensure that the structural integrity of 
the aircraft is maintained.
    The FAA disagrees, since the FAA needs to review each individual 
extension request, which can then be supported through the AMOC 
process, provided sufficient justification is available. Sufficient 
justification, supported by an acceptable level of safety, is needed to 
grant such a request. In such situations, the operator should work with 
the FAA as early as possible. The FAA has not revised this AD in this 
regard.

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

[[Page 9597]]

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.

Material Incorporated by Reference Under 1 CFR Part 51

    EASA AD 2024-0031 specifies new or more restrictive airworthiness 
limitations for airplane structures and safe life limits.
    This AD also requires the following material, which the Director of 
the Federal Register approved for incorporation by reference as of 
September 5, 2023 (88 FR 50005, August 1, 2023):
    <bullet> EASA AD 2022-0085, dated May 12, 2022.
    <bullet> EASA AD 2023-0008, dated January 16, 2023.
    This AD also requires EASA AD 2023-0151, dated July 25, 2023, which 
the Director of the Federal Register approved for incorporation by 
reference as of April 19, 2024 (89 FR 18769, March 15, 2024).
    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 affects 1,898 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:
    The FAA estimates the total cost per operator for the retained 
actions from AD 2023-13-10 to be $7,650 (90 work-hours x $85 per work-
hour).
    The FAA estimates the total cost per operator for the retained 
actions from AD 2024-04-03 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 actions 
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,
    (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.

European Union Aviation Safety Agency (EASA) AD 2022-0085, dated May 
12, 2022 (EASA AD 2022-0085), and EASA AD 2023-0008, dated January 
16, 2023 (EASA AD 2023-0008). Where EASA AD 2023-0008 affects the 
same airworthiness limitations as those in EASA AD 2022-0085, the 
airworthiness limitations referenced in EASA AD 2023-0008 prevail. 
Accomplishing the revision of the existing maintenance or inspection 
program required by paragraph (n) of this AD terminates the 
requirements of this paragraph.

(h) Retained Exceptions to EASA AD 2022-0085 and EASA AD 2023-0008, 
With No Changes

    This paragraph restates the exceptions specified in paragraph 
(p) of AD 2023-13-10, with no changes.
    (1) The requirements specified in paragraphs (1) and (2) of EASA 
AD 2022-0085 and of EASA AD 2023-0008 do not apply to this AD.
    (2) Paragraph (3) of EASA AD 2022-0085 and of EASA AD 2023-0008 
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 September 5, 2023 (the effective date of AD 2023-13-10).
    (3) The initial compliance time for doing the tasks specified in 
paragraph (3) of EASA AD 2022-0085 and of EASA AD 2023-0008 is at 
the applicable ``thresholds'' as incorporated by the requirements of 
paragraph (3) of EASA AD 2022-0085 and of EASA AD 2023-0008, 
respectively, or within 90 days after September 5, 2023 (the 
effective date of AD 2023-13-10), whichever occurs later. Where EASA 
AD 2023-0008 affects the same airworthiness limitations as those in 
EASA AD 2022-0085, the airworthiness limitations referenced in EASA 
AD 2023-0008 prevail.
    (4) The provisions specified in paragraphs (4) and (5) of EASA 
AD 2022-0085 and of EASA AD 2023-0008 do not apply to this AD.
    (5) This AD does not adopt the ``Remarks'' section of EASA AD 
2022-0085 and of EASA AD 2023-0008.

(i) Retained Restrictions on Alternative Actions and Intervals From AD 
2023-13-10, With a New Exception

    This paragraph restates the requirements of paragraph (q) of AD 
2023-13-10, with a new exception. Except as required by paragraphs 
(j) and (n) 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) and intervals are allowed 
unless they are approved as specified in the provisions of the 
``Ref. Publications'' section of EASA AD 2022-0085 or EASA AD 2023-
0008, as applicable.

(j) Retained Revision of the Existing Maintenance or Inspection Program 
From AD 2024-04-03, With New Terminating Action

    This paragraph restates the requirements of paragraph (g) of AD 
2024-04-03, with new terminating action. For airplanes with an 
original airworthiness certificate or original export certificate of 
airworthiness issued on or before May 12, 2023: 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-
0151, dated July 25, 2023 (EASA AD 2023-0151). Accomplishing the 
revision of the existing maintenance or inspection program required 
by paragraph (n) of this AD terminates the requirements of this 
paragraph.

(k) Retained Exceptions to EASA AD 2023-0151, With No Changes

    This paragraph restates the exceptions specified in paragraph 
(h) of AD 2024-04-03, with no changes.
    (1) This AD does not adopt the requirements specified in 
paragraphs (1) and (2) of EASA AD 2023-0151.
    (2) Where paragraph (3) of EASA AD 2023-0151 specifies ``Within 
12 months after the effective date of this AD, revise the approved 
AMP,'' this AD requires replacing that text with ``Within 90 days 
after April 19, 2024 (the effective date of AD 2024-04-03), revise 
the existing maintenance or inspection program, as applicable.''
    (3) The initial compliance time for doing the tasks specified in 
paragraph (3) of EASA AD 2023-0151 is at the applicable ``associated 
thresholds'' as incorporated by the requirements of paragraph (3) of 
EASA AD 2023-0151, or within 90 days after April 19, 2024 (the 
effective date of AD 2024-04-03), whichever occurs later.
    (4) This AD does not adopt the provisions specified in paragraph 
(4) of EASA AD 2023-0151.
    (5) This AD does not adopt the ``Remarks'' section of EASA AD 
2023-0151.

(l) Retained Restrictions on Alternative Actions and Intervals From AD 
2024-04-03, With No Changes

    This paragraph restates the requirements of paragraph (i) of AD 
2024-04-03, with no changes. Except as required by paragraph (n) of 
this AD, after the existing maintenance or inspection program has 
been revised as required by paragraph (j) of this AD, no alternative
