Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2017-19-
24, which applies to Model A319-111, -112, -113, -114, -115, -131, -
132, and -133 airplanes; Model A320-211, -212, -214, -231, -232, and -
233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, 
and -232 airplanes. The FAA is also superseding AD 2018-16-04, which 
applies to Airbus SAS Model A320-216, -251N, and -271N airplanes; and 
Model A321-251N, -253N, and -271N airplanes; as well as the models in 
AD 2017-19-24. Those ADs required revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more

[[Page 65191]]

restrictive maintenance requirements and airworthiness limitations. 
Since AD 2018-16-04 was issued, the FAA has determined that new or more 
restrictive airworthiness limitations are necessary. This AD requires 
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 incorporated by reference. This AD was prompted by a determination 
that new or more restrictive airworthiness limitations are necessary. 
The FAA is issuing this AD to address the unsafe condition on these 
products.

DATES: This AD is effective November 19, 2020.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 19,

SUPPLEMENTARY INFORMATION:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0034, dated February 25, 2020 
(``EASA AD 2020-0034'') (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, A319-112, A319-113, A319-114, A319-115, A319-131, A319-132, A319-
133, A319-151N, and A319-153N airplanes; Model A320-211, A320-212, 
A320-214, A320-215, A320-216, A320-231, A320-232, A320-233, A320-251N, 
A320-252N, A320-253N, A320-271N, A320-272N, and A320-273N airplanes; 
and Model A321 series airplanes. EASA AD 2020-0034 superseded EASA AD 
2017-0170 (which corresponds to FAA AD 2018-16-04 (AD 2018-16-04, 
Amendment 39 19344 (83 FR 39581, August 10, 2018) (``AD 2018-16-04'')). 
Model A320-215 airplanes are not certified 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.
    Airplanes with an original airworthiness certificate or original 
export certificate of airworthiness issued after November 7, 2019, must 
comply with the airworthiness limitations specified as part of the 
approved type design and referenced on the type certificate data sheet; 
this AD therefore does not include those airplanes in the 
applicability.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2017-19-24, Amendment 39-19054 (82 FR 
44900, September 27, 2017) (``AD 2017-19-24''); and 2018-16-04; for all 
Model A318 series airplanes; Model A319-111, -112, -113, -114, -115, -
131, -132, -133, -151N, and -153N airplanes; Model A320 series 
airplanes; and Model A321 series airplanes. The NPRM published in the 
Federal Register on May 7, 2020 (85 FR 27167). The NPRM was prompted by 
a determination that new or more restrictive airworthiness limitations 
are necessary. The NPRM proposed to address the risks associated with 
the effects of aging on airplane systems. Such effects could change 
system characteristics, leading to an increased potential for failure 
of certain life-limited parts, and reduced structural integrity or 
controllability 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.

Support for the Proposed AD

    United Airlines and an anonymous commenter expressed support for 
the proposed AD.

Request To Confirm Intent To Allow Use of Later ALS Revisions

    Delta Air Lines (Delta) 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 variations or revisions in their entirety to comply with the 
requirements of this AD, as long as they follow the requirements of 
paragraph (k) of this AD--that they are approved in the provisions of 
the ``Ref. Publications'' section of EASA AD 2020-0034.

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

    Delta 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 (l)(1) of the 
proposed AD. Delta provided no reason or justification for the request.
    The FAA agrees to clarify. The previous format of the FAA's 
airworthiness limitation ADs included a paragraph that specified that 
no alternative actions (e.g., inspections) or intervals may be used 
unless the actions or intervals are approved as an alternative method 
of compliance

[[Page 65192]]

(AMOC) in accordance with the procedures specified in the AMOCs 
paragraph under ``Other FAA 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, interval, or CDCCL. 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 as proposed, except for minor 
editorial changes. The FAA has determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2020-0034 describes airworthiness limitations for system 
equipment maintenance requirements.
    This AD also requires Airbus SAS A318/A319/A320/A321 Airworthiness 
Limitations Section (ALS) Part 4, ``System Equipment Maintenance 
Requirements (SEMR),'' Revision 05, dated April 6, 2017, which the 
Director of the Federal Register approved for incorporation by 
reference as of September 14, 2018 (83 FR 39581, August 10, 2018).
    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 2018-16-04 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. 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 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.

(d) Subject

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

(e) Reason

    This AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary. The FAA is 
issuing this AD to address the risks associated with the effects of 
aging on airplane systems. Such effects could change system 
characteristics, leading to an increased potential for failure of 
certain life-limited parts, and reduced structural integrity or 
controllability of the airplane.

unless already done.

(g) Retained Maintenance or Inspection Program Revision, With No 
Changes

    This paragraph restates the requirements of paragraph (g) of AD 
2018-16-04, with no changes. Within 90 days after September 14, 2018 
(the effective date of AD 2018-16-04),

[[Page 65193]]

revise the existing maintenance or inspection program, as 
applicable, to incorporate Airbus SAS A318/A319/A320/A321 
Airworthiness Limitations Section (ALS) Part 4, ``System Equipment 
Maintenance Requirements (SEMR),'' Revision 05, dated April 6, 2017. 
The initial compliance time for doing the revised actions is at the 
applicable time specified in Airbus SAS A318/A319/A320/A321 ALS Part 
4, ``System Equipment Maintenance Requirements (SEMR),'' Revision 
05, dated April 6, 2017. Accomplishing the maintenance or inspection 
program revision required by paragraph (i) of this AD terminates the 
requirements of this paragraph.

(h) Retained No Alternative Actions or Intervals, With a New Exception

    This paragraph restates the requirements of paragraph (h) of AD 
2018-16-04, with a new exception. Except as required by paragraph 
(i) of this AD, after the maintenance or inspection program has been 
revised as required by paragraph (g) of this AD, no alternative 
actions (e.g., inspections) or intervals may be used unless the 
actions or intervals are approved as an alternative method of 
compliance (AMOC) in accordance with the procedures specified in 
paragraph (l)(1) of this AD.

(i) New Maintenance or Inspection Program Revision

    Except as specified in paragraph (j) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with, European Union Aviation Safety Agency (EASA) AD 
2020-0034, dated February 25, 2020 (``EASA AD 2020-0034''). 
Accomplishing the maintenance or inspection program revision 
required by this paragraph terminates the requirements of paragraph 
(g) of this AD.

(j) Exceptions to EASA AD 2020-0034

    (1) The requirements specified in paragraphs (1) and (2) of EASA 
AD 2020-0034 do not apply to this AD.
    (2) Paragraph (3) of EASA 2020-0034 specifies revising ``the 
AMP'' within 12 months after its effective date, but this AD 
requires revising the existing maintenance or inspection program, as 
applicable, to incorporate the ``tasks and associated thresholds and 
intervals'' specified in paragraph (3) of EASA 2020-0034 within 90 
days after the effective date of this AD.
    (3) The initial compliance time for doing the tasks specified in 
paragraph (3) of EASA 2020-0034 is at the applicable ``associated 
thresholds'' specified in paragraph (3) of EASA AD 2020-0034, or 
within 90 days after the effective date of this AD, whichever occurs 
later.
    (4) The provisions specified in paragraphs (4) and (5) of EASA 
AD 2020-0034 do not apply to this AD.
    (5) The ``Remarks'' section of EASA AD 2020-0034 does not apply 
to this AD.

(k) New Provisions for Alternative Actions and Intervals

    After the maintenance or inspection program has been revised as 
required by paragraph (i) of this AD, no alternative actions (e.g., 
inspections) and intervals are allowed unless they are approved in 
the provisions of the ``Ref. Publications'' section of EASA AD 2020-
0034.

(l) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Large Aircraft Section, 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 local Flight 
Standards District Office, as appropriate. If sending information 
directly to the Large Aircraft Section, International Validation 
Branch, send it to the attention of the person identified in 
paragraph (m) of this AD. Information may be emailed to: <a href="/cdn-cgi/l/email-protection#a69f8be7f0f58be7eff48b9195968be7ebe9e5e6c0c7c788c1c9d0"><span class="__cf_email__" data-cfemail="84bda9c5d2d7a9c5cdd6a9b3b7b4a9c5c9cbc7c4e2e5e5aae3ebf2">[email&#160;protected]</span></a>.
    (i) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (ii) AMOCs approved previously for AD 2018-16-04 are approved as 
AMOCs for the corresponding provisions of EASA AD 2020-0034 that are 
required by paragraph (g) of this AD.
    (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, Large Aircraft 
Section, 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): For any service information 
referenced in EASA AD 2020-0034 that contains RC procedures and 
tests: Except as required by paragraph (l)(2) of this AD, RC 
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 accepted methods in accordance with the 
operator's maintenance or inspection program without obtaining 
approval of an AMOC, provided the procedures and tests identified as 
RC can be done and the airplane can be put back in an airworthy 
condition. Any substitutions or changes to procedures or tests 
identified as RC require approval of an AMOC.
