Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2023-13-10 and AD 2024-04-03, which apply to certain Airbus SAS Model 
A318, A319, A320, and A321 series airplanes. AD 2023-13-10 and AD 2024-
04-03 require revising the existing maintenance or inspection program, 
as applicable, to incorporate new or more restrictive airworthiness 
limitations. Since the FAA issued AD 2023-13-10 and AD 2024-04-03, the 
FAA has determined that new or more restrictive airworthiness 
limitations are necessary. This proposed AD would continue to require 
certain actions in AD 2023-13-10 and all actions in AD 2024-04-03 and 
would require revising the existing maintenance or inspection program, 
as applicable, to incorporate new or more restrictive airworthiness 
limitations, 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 address the unsafe condition on these 
products.

DATES: The FAA must receive comments on this proposed AD by November 4, 
2024.

Background

    The FAA issued AD 2023-13-10, Amendment 39-22495 (88 FR 50005, 
August 1, 2023) (AD 2023-13-10), for certain Airbus SAS Model A318, 
A319, A320, and A321 series airplanes. AD 2023-13-10 was prompted by an 
MCAI originated by EASA, which is the Technical Agent for the Member 
States of the European Union. EASA issued AD 2023-0008, dated January 
16, 2023 (EASA AD 2023-0008) and AD 2022-0085, dated May 12, 2022 (EASA 
AD 2022-0085) (which correspond to FAA AD 2023-13-10), to correct an 
unsafe condition.
    AD 2023-13-10 requires revising the existing maintenance or 
inspection program, as applicable, to incorporate additional new or 
more restrictive airworthiness limitations. The FAA issued AD 2023-13-
10 to address fatigue cracking, accidental damage, or corrosion in 
principal structural elements, which could result in reduced structural 
integrity of the airplane.
    The FAA issued AD 2024-04-03, Amendment 39-22682 (89 FR 18769, 
March 15, 2024) (AD 2024-04-03), for certain Airbus SAS Model A318, 
A319, A320, and A321 series airplanes. AD 2024-04-03 was prompted by an 
MCAI originated by EASA. EASA issued AD 2023-0151, dated July 25, 2023 
(EASA AD 2022-0151) (which corresponds to FAA AD 2024-04-03), to 
correct an unsafe condition.
    AD 2024-04-03 requires revising the existing maintenance or 
inspection program, as applicable, to incorporate additional new or 
more restrictive airworthiness limitations. The FAA issued 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. AD 2024-04-03 specifies that accomplishing 
the revision required by that AD terminates certain requirements of AD 
2023-13-10.

Actions Since AD 2023-13-10 and AD 2024-04-03 Were Issued

    Since the FAA issued AD 2023-13-10 and AD 2024-04-03, EASA 
superseded AD 2022-0085, AD 2023-0008, and AD 2023-0151 and issued EASA 
AD 2024-0031, dated January 31, 2024; corrected February 1, 2024 (EASA 
AD 2024-0031) (referred to after this as the MCAI), for all Airbus SAS 
Model A318-111, -112, -121, and -122; A319-111, -112, -113, -114, -115, 
-131, -132, -133, -151N, -153N, and -171N; A320-211, -212, -214, -215, 
-216, -231, -232, -233, -251N, -252N, -253N, -271N, -272N, and -273N; 
and A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -251NX, 
-252N, -252NX, -253N, -253NX, -271N, -271NX, -272N, and -272NX 
airplanes. Model A320-215 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 new or more restrictive airworthiness limitations have 
been developed.
    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-2024-2145.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed EASA AD 2024-0031. This material specifies new or 
more restrictive airworthiness limitations for airplane structures and 
safe life limits.
    This proposed AD would also require 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
<bullet> EASA AD 2023-0008

    This proposed AD would also require EASA AD 2023-0151, 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.

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 NPRM after determining that 
the unsafe condition described previously is likely to exist or develop 
in other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would retain all requirements of AD 2024-04-03 and 
certain requirements of AD 2023-13-10. This proposed AD would also 
require revising the existing maintenance or inspection program, as 
applicable, to incorporate additional new or more restrictive 
airworthiness limitations, which are specified in EASA AD 2024-0031 
already described, as proposed for incorporation by reference. Any 
differences with EASA AD 2024-0031 are identified as exceptions in the 
regulatory text of this proposed AD.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections) and 
Critical Design Configuration Control Limitations (CDCCLs). Compliance 
with these actions and CDCCLs is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired in 
the areas addressed by this proposed 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 (q)(1) 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 retain the IBR of EASA AD 2022-0085, EASA AD 2023-0008, 
and EASA AD 2023-0151, and incorporate EASA AD 2024-0031 by reference 
in the FAA final rule. This proposed AD would, therefore, require 
compliance with

[[Page 77047]]

EASA AD 2022-0085, EASA AD 2023-0008, EASA AD 2023-0151, and EASA AD 
2024-0031 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 2022-0085, EASA AD 2023-0008, EASA AD 2023-0151, or 
EASA AD 2024-0031 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 2022-0085, EASA AD 2023-0008, EASA 
AD 2023-0151, or EASA AD 2024-0031. Material required by EASA AD 2022-
0085, EASA AD 2023-0008, EASA AD 2023-0151, and EASA AD 2024-0031 for 
compliance will be available at regulations.gov by searching for and 
locating Docket No. FAA-2024-2145 after the FAA final rule 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 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), intervals, or CDCCLs may be used unless the actions, 
intervals, and CDCCLs 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, Intervals, and CDCCLs'' paragraph that does not 
specifically refer to AMOCs, but operators may still request an AMOC to 
use an alternative action, interval, or CDCCL.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 1,898 airplanes of U.S. registry. The FAA estimates the 
following costs to comply with this proposed AD:
    The FAA estimates the total cost per operator for the retained 
actions from AD2023-13-10 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 proposed 
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

    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.

 (d) Subject

    Air Transport Association (ATA) of America Code 05, Time Limits/
Maintenance Checks.

 (e) Unsafe Condition

    This AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary. 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.

 (f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

 (g) Retained Revision of the Existing Maintenance or Inspection 
Program From AD 2023-13-10, With New Terminating Action

    This paragraph restates the requirements of paragraph (o) of AD 
2023-13-10, with new terminating action. For airplanes with an 
original airworthiness certificate or original export certificate of 
airworthiness issued on or before November 10, 2022: 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 2022-0085, 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
