reason for any recommended change, and include supporting data. The FAA 
will consider all comments received by the closing date and may amend 
this final rule 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 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 final rule, 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 final rule. Submissions containing CBI 
should be sent to Dan Rodina, Aerospace Engineer, Large Aircraft 
Section, International Validation Branch, FAA, 2200 South 216th St., 
Des Moines, WA 98198; 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

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2022-0172, dated August 22, 2022 
(EASA AD 2022-0172) (also referred to as the MCAI), to correct an 
unsafe condition for all Airbus SAS Model A310-203, A310-204, A310-221, 
A310-222, A310-203C, A310-304, A310-308, A310-322, A310-324, and A310-
325 airplanes. Model A310-203C and A310-308 airplanes are not 
certificated by the FAA and are not included on the U.S. type 
certificate data sheet; this AD therefore does not include those 
airplanes in the applicability. The MCAI states that new or more 
restrictive airworthiness limitations have been developed.
    EASA AD 2022-0172 specifies that it requires a task (limitation) 
related to the replacement of life-limited parts already in Airbus A310 
Airworthiness Limitations Section (ALS) Part 1 Safe Life Airworthiness 
Limitations Items (SL-ALI) Revision 02 that is required by EASA AD 
2017-0204 (which corresponds to FAA AD 2018-18-19, Amendment 39-19398 
(83 FR 47056, September 18, 2018) (AD 2018-18-19)), and that 
incorporation of EASA AD 2022-0172 invalidates (terminates) prior 
instructions for that task. This AD therefore terminates the 
limitations for SL-ALI, as required by paragraph (g)(3) of AD 2018-18-
19, for Model A310-203, -204, -221, -222, -304, -322, -324, and -325 
airplanes only.
    The FAA is issuing this AD to address fatigue damage in principal 
structural

[[Page 20747]]

elements. The unsafe condition, if not addressed, 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-2023-0173.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed EASA AD 2022-0172, which specifies new or more 
restrictive airworthiness limitations for airplane structures and safe 
life limits. This service information 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 
described 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.

AD Requirements

    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 2022-0172 
described previously, as incorporated by reference. Any differences 
with EASA AD 2022-0172 are identified as exceptions in the regulatory 
text of this AD.
    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 (k)(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, 
EASA AD 2022-0172 is incorporated by reference in this AD. This AD 
requires compliance with EASA AD 2022-0172 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 2022-0172 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-
0172. Service information required by EASA AD 2022-0172 for compliance 
will be available at regulations.gov under Docket No. FAA-2023-0173 
after this 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 
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.

Justification for Immediate Adoption 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 
foregoing 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

    The requirements of the Regulatory Flexibility Act (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 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

[[Page 20748]]

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.
