SUMMARY: We are superseding Airworthiness Directive (AD) 2015-05-02, 
which applied to all Airbus Model

[[Page 49092]]

A318 and A319 series airplanes; Model A320-211, -212, -214, -231, -232, 
and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -
231, and -232 airplanes. AD 2015-05-02 required revising the 
maintenance or inspection program to incorporate new, more restrictive 
airworthiness limitations. This new AD requires revising the 
maintenance or inspection program to incorporate new or revised 
structural inspection requirements and adds airplanes to the 
applicability. This AD was prompted by an evaluation by the design 
approval holder (DAH), which indicates that principal structural 
elements and certain life-limited parts are subject to widespread 
fatigue damage (WFD). We are issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective November 28, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 28, 
2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of March 
2, 2015 (80 FR 3871, January 26, 2015).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 to supersede AD 2015-05-02, Amendment 39-18112 (80 
FR 15152, March 23, 2015) (``AD 2015-05-02''). AD 2015-05-02 applied to 
all Airbus Model A318 and A319 series 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 SNPRM published in the 
Federal Register on May 19, 2017 (82 FR 22910) (``the SNPRM''). We 
preceded the SNPRM with a notice of proposed rulemaking (NPRM) that 
published in the Federal Register on May 11, 2016 (81 FR 29198) (``the 
NPRM''). The NPRM was prompted by an evaluation by the DAH, which 
indicates that principal structural elements and certain life limited 
parts are subject to WFD. The NPRM proposed to require revising the 
maintenance or inspection program, as applicable, to incorporate new or 
revised structural inspection requirements. The SNPRM proposed to 
require more restrictive airworthiness limitations and add Model A320-
251N and -271N airplanes to the applicability. We are issuing this AD 
to prevent fatigue cracking, accidental damage, or corrosion in 
principal structural elements, and WFD, which could result in reduced 
structural integrity of the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2016-0239, dated December 2, 2016 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition. The MCAI states:

    The airworthiness limitations for Airbus A320 family aeroplanes 
are currently included in Airbus A318/A319/A320/A321 Airworthiness 
Limitations Section (ALS) documents. The Damage Tolerant 
Airworthiness Limitation Items are published in ALS Part 2, approved 
by EASA.
    The instructions contained in the ALS Part 2 have been 
identified as mandatory actions for continued airworthiness. Failure 
to comply with these instructions could result in an unsafe 
condition.
    Previously, EASA issued AD 2015-0083 to require accomplishment 
of all maintenance tasks as described in ALS Part 2 at Revision 03. 
Since that [EASA] AD was issued, Airbus issued Revision 04, and 
later on Revision 05 of the ALS Part 2, including new and/or more 
restrictive items, and new A320 models were certified.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2015-0083, which is superseded, expands the 
Applicability by adding the models A320-251N and A320-271N, requires 
accomplishment of all maintenance tasks as described in the ALS Part 
2, Revision 05 (hereafter referred to as `the ALS' in this [EASA] 
AD), and provides specific compliance times for ALS task 572021-01-1 
(Wide Spread Fatigue Damage related).

    The required action is revising the maintenance or inspection 
program to incorporate new or revised structural inspection 
requirements. The unsafe condition is fatigue cracking, accidental 
damage, or corrosion in principal structural elements, and WFD, which 
could result in reduced structural integrity of the airplane. You may 
examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
6429.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the SNPRM and 
the FAA's response to the comment.

Request To Reference Revised Service Information

    American Airlines (AAL) requested that we revise the SNPRM to 
incorporate Airbus A318/A319/A320/A321 ALS Part 1--Safe Life 
Airworthiness Limitation Items (SL--ALI), Revision 05, dated April 6, 
2017, including Variations 5.1 and 5.2; and Airbus A318/A319/A320/A321 
ALS Part 2--Damage Tolerant Airworthiness Limitation Items (DT--ALI), 
Revision 06, dated April 10, 2017.
    We partially agree with AAL's request. We agree that operators 
should use the latest service information, and we agree to account for 
AAL's request in this AD. However, we do not agree to require the 
revised service information in this final rule since it would expand 
the scope, requiring additional notice and comment. We find that 
delaying this action would be inappropriate in light of the identified 
unsafe condition. We are considering further rulemaking to supersede 
this final rule to require incorporating the revised service 
information.
    We have added paragraph (l)(1)(iii) to this AD to specify that the 
previous

[[Page 49093]]

alternative methods of compliance (AMOCs) that are approved for AD 
2015-05-02 are approved as AMOCs for the corresponding provisions of 
paragraphs (i) and (j) of this AD. The previous AMOCs include Airbus 
A318/A319/A320/A321 ALS Part 1--Safe Life Airworthiness Limitation 
Items (SL--ALI), Revision 05, dated April 6, 2017, including Variations 
5.1 and 5.2; and Airbus A318/A319/A320/A321 ALS Part 2--Damage Tolerant 
Airworthiness Limitation Items (DT--ALI), Revision 06, dated April 10, 
2017.

Conclusion

    We reviewed the available data, including the comment received, and 
determined that air safety and the public interest require adopting 
this AD as proposed except for minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
SNPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM.

Related Service Information Under 1 CFR Part 51

    Airbus has issued the following service information.
     A318/A319/A320/A321 ALS Part 1--Safe Life Airworthiness 
Limitation Items (SL--ALI), Revision 04, dated June 20, 2016. This 
service information describes mandatory instructions and airworthiness 
limitations for the ``safe-life'' structure.
     A318/A319/A320/A321 ALS Part 2--Damage Tolerant 
Airworthiness Limitation Items (DT--ALI), Revision 05, dated July 8, 
2016. This service information describes mandatory instructions and 
airworthiness limitations arising from fatigue and damage tolerance 
evaluation of damage tolerant structural elements.
    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 the ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 1,182 airplanes of U.S. registry.
    The actions required by AD 2015-05-02, and retained in this AD, 
take about 2 work-hours per product, at an average labor rate of $85 
per work-hour. Based on these figures, the estimated cost of the 
actions that are required by AD 2015-05-02 is $170 per product.
    We also estimate that it will take about 2 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $200,940, or $170 per product.

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.
    We are 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

Regulatory Findings

    We determined that 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. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.
