SUPPLEMENTARY INFORMATION:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0036R1, dated June 24, 2020 
(``EASA AD 2020-0036R1'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for all Airbus SAS Model A318 series airplanes; Model A319-
111, -112, -113, -114, -115, -131, -132, -133, -151N, and -153N 
airplanes; Model A320-211, -212, -214, -215, -216, -231, -232, -233, -
251N, -252N, -253N, -271N, -272N, and -273N airplanes; and Model A321 
series airplanes. EASA AD 2020-0036R1 revised EASA AD 2020-0036, dated 
February 26, 2020 (``EASA AD 2020-0036'') (which the FAA referred to as 
the appropriate source of service information for accomplishing the 
actions specified in the notice of proposed rulemaking (NPRM)), and 
superseded EASA AD 2018-0288 (which corresponds to FAA AD 2019-23-01 
(AD 2019-23-01, Amendment 39-19794 (84 FR 66579, December 5, 2019) 
(``AD 2019-23-01'')). Model A320-215 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 FAA issued a NPRM to amend 14 CFR part 39 to supersede AD 2019-
23-01, for certain Airbus SAS Model A318 series airplanes; A319-111, -
112, -113, -114, -115, -131, -132, and -133 airplanes; A320-211, -212, 
-214, -216, -231, -232, -233, -251N, -252N, and -271N airplanes; and 
A321 series airplanes. AD 2019-23-01 required revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations. AD 2019-23-01 required 
airworthiness limitations that are newer or more restrictive than those 
specified in AD 2018-25-02, Amendment 39-19513 (83 FR 62690, December 
6, 2018) (``AD 2018-25-02''). AD 2019-23-01 specified that 
accomplishing the revision required by paragraph (i) of AD 2019-23-01 
terminated all requirements of AD 2018-25-02. The NPRM published in the 
Federal Register on June 1, 2020 (85 FR 33046). The NPRM was prompted 
by a determination that new or more restrictive airworthiness 
limitations are necessary and models need to be added

[[Page 65198]]

to the applicability. The NPRM proposed to require revising the 
existing maintenance or inspection program, as applicable, to 
incorporate new or more restrictive airworthiness limitations.
    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. See the MCAI 
for additional background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The following presents the comments 
received on the NPRM and the FAA's response to each comment.

Request To Use Revised EASA AD

    United Airlines (UAL) and American Airlines (AAL) supported the 
NPRM and asked that the proposed AD refer to EASA AD 2020-0036R1 for 
accomplishing the required actions (EASA AD 2020-0036, dated February 
26, 2020, was referred to in the proposed AD). UAL stated that EASA AD 
2020-0036R1 will allow operators to use current requirements and 
prevent issuing a revised AD to require compliance with the revised 
EASA AD. AAL also noted that operators should be allowed to use the 
revised EASA AD.
    The FAA agrees with the commenters' requests. EASA AD 2020-0036R1 
does not substantively change the requirements of EASA AD 2020-0036. 
Instead, EASA AD 2020-0036R1 adds credit for EASA AMOC approval 
10071736 to EASA AD 2018-0288, and notes that Issue 02 of the ALS has 
been released. The FAA has changed all references in this AD from EASA 
AD 2020-0036 to EASA AD 2020-0036R1, added paragraph (l) to this AD to 
provide credit for Rev 0, and changed subsequent paragraphs of this AD 
accordingly.

Request To Confirm Intent To Allow Use of Later ALS Revisions

    Delta Air Lines (DAL) requested confirmation that the FAA intended 
to allow the use of later ALS revisions to comply with the proposed AD. 
The commenter noted that previous ADs required an alternative method of 
compliance (AMOC) to use a later ALS revision.
    The FAA confirms that it intends to allow the use of applicable 
later ALS revisions to comply with the requirements of this AD. This AD 
refers to EASA AD 2020-0036R1 as the appropriate source of service 
information for accomplishing the required actions. EASA AD 2020-0036R1 
includes the Ref. Publications section, which accepts the use of later 
approved variations or revisions of the referenced ALS document for 
compliance. Therefore, applicable later approved ALS revisions are 
acceptable.

Request To Allow AMOC Approval for Alternative Actions or Intervals 
After Revision of Maintenance or Inspection Program

    DAL requested that paragraph (k) of the proposed AD be changed to 
also allow alternative actions and intervals after the maintenance and 
inspection program has been revised, provided that the actions or 
intervals are approved as an alternative method of compliance (AMOC) in 
accordance with the procedures specified in paragraph (n)(1) of the 
proposed AD. Delta provided no reason or justification for the request.
    The FAA acknowledges the commenter's request and provides 
clarification that, if applicable, requesting an AMOC is always an 
option; therefore, it is not necessary to revise paragraph (k) of this 
AD. This AD has not been changed regarding this request.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
received, and determined that air safety and the public interest 
require adopting this final rule with the change described previously 
and minor editorial changes. The FAA has determined that these minor 
changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    The FAA also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this final 
rule.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2020-0036R1 describes new or more restrictive airworthiness 
limitations for damage tolerance of airplane structures.
    This AD also requires Airbus A318/A319/A320/A321 Airworthiness 
Limitations Section (ALS) Part 2-Damage Tolerant Airworthiness 
Limitation Items (DT-ALI), Revision 07, dated June 13, 2018, which the 
Director of the Federal Register approved for incorporation by 
reference as of January 9, 2020 (84 FR 66579, December 5, 2019).
    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 1,553 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 2019-23-01 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. In the past, the agency has estimated that this action 
takes 1 work-hour per airplane. 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

    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.

[[Page 65199]]

    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.
