SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Airbus Model A318 
series airplanes and Model A319 series airplanes; all Model A320-211, -
212, -214, -216, -231, -232, and -233 airplanes; and all Model A321-
111, -112, -131, -211, -212, -213, -231, and -232 airplanes. The NPRM 
published in the Federal Register on January 12, 2018 (83 FR 1579) 
(``the NPRM''). The NPRM was prompted by an evaluation by the DAH 
indicating that the holes of the upper cleat to upper stringer 
attachments at certain areas of the left- and right-hand wings are 
subject to WFD. The NPRM proposed to require modifying the holes of the 
upper cleat to upper stringer attachments at certain areas of the left- 
and right-hand wings. We are issuing this AD to prevent fatigue 
cracking in the stringer attachment holes of the wings, which could 
result in reduced structural integrity of the wings.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0117, dated July 7, 2017 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Airbus Model A318 series airplanes and 
Model A319 series

[[Page 19926]]

airplanes; all Model A320-211, -212, -214, -216, -231, -232, and -233 
airplanes; and all Model A321-111, -112, -131, -211, -212, -213, -231, 
and -232 airplanes. The MCAI states:

    Within the scope of work of service life extension for A320 
aeroplanes and of widespread fatigue damage evaluations, it has been 
determined that a structural modification is required to allow the 
aeroplanes to continue operation up to the limit of validity (LoV).
    This condition, if not corrected, may affect the structural 
integrity of the wing.
    To address this potential unsafe condition, Airbus issued 
[service bulletin] SB A320-57-1208, providing instructions to 
oversize the holes of the upper cleat to upper stringer attachments 
at Rib 2 to Rib 7 (inclusive).
    For the reason described above, this [EASA] AD requires 
modification of the affected holes.

    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-2017-
1245.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM and 
the FAA's response to each comment. United Airlines agreed with the 
intent of the NPRM.

Request To Clarify Applicability

    Allegiant Air asked that we clarify the manufacturer serial numbers 
(MSNs) identified in the applicability section of the proposed AD. 
Allegiant Air stated that the effectivity specified in Airbus Service 
Bulletin A320-57-1208, dated November 21, 2016, identifies airplanes up 
to and including MSN 7493, and asked about airplanes having MSNs higher 
than 7493. Allegiant Air noted that it has 11 Model A320 airplanes with 
MSNs outside those listed in Airbus Service Bulletin A320-57-1208, 
dated November 21, 2016. Allegiant Air added that it understands the AD 
takes precedence over the service information, but there are several 
configurations listed therein. Allegiant Air also added that since the 
MSNs in question are not listed in the effectivity of the service 
information, an operator with an MSN outside the effectivity will not 
know which modification kit to order.
    We agree to clarify. The effectivity in Airbus Service Bulletin 
A320-57-1208, dated November 21, 2016, does not include all MSNs for 
Model A320 airplanes, and the applicability specified in paragraph (c) 
of this AD includes all MSNs for Model A320 airplanes, except for 
airplanes having certain modifications. We acknowledge that the 
referenced service information may not be adequate for certain airplane 
configurations. Therefore, we have revised paragraph (g) of this AD to 
provide an option for doing the modification, including identification 
of the appropriate modification kit, using a method approved by the 
Manager, International Section, Transport Standards Branch, FAA; or 
EASA; or Airbus's EASA Design Organization Approval (DOA).
    In addition, Airbus has informed us that Revision 1 of the 
referenced service information will expand the effectivity to include 
MSNs up to 8555. Airbus has also informed us that, upon request, it 
will issue a technical adaptation as an interim method of compliance 
until a revised service bulletin is issued.

Conclusion

    We reviewed the relevant data, considered the comments 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 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Airbus Service Bulletin A320-57-1208, dated 
November 21, 2016. This service information describes procedures for 
modifying the stringer attachments at rib 2 through rib 7 of the left- 
and right-hand wings. The modification includes oversizing the holes, 
doing an eddy current inspection of the affected holes for damage, and 
repair. 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 1,136 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs

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

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this AD.

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

[[Page 19927]]

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.
