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 all Airbus Model A310-203, 
-221, -222, -304, -322, -324, and -325 airplanes. The NPRM published in 
the Federal Register on February 8, 2018 (83 FR 5584) (``the NPRM'').
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0122, dated July 18, 2017 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for all Airbus Model A310-203, -221, -222, -304, -308, 
-322, -324, and -325 airplanes. The MCAI states:

    In response to the FAA Part 26 rule, wing structural items of 
the Airbus A310 design were assessed regarding Widespread Fatigue 
Damage (WFD) phenomenon. One outcome was that the outer wing lower 
junction is prone to WFD at level of the first fasteners row, close 
to Rib 1 between Frame (FR) 40 and FR 47.
    This condition, if not corrected, could reduce the structural 
integrity of the wing.
    Prompted by the conclusion of WFD analysis, Airbus issued 
Service Bulletin (SB) A310-57-2105 to provide modification 
instructions. The accomplishment of this modification at the 
specified time will recondition/renovate/extend the life of the 
fasteners holes at Rib 1, in order to reach the Limit Of Validity.
    For the reasons described above, this [EASA] AD requires cold 
working of the affected holes at Rib 1, stiffeners 1 to 14, on both 
outer wings between FR 40 and FR 47.

    Required actions include a modification of the fastener holes at 
rib 1, stiffeners 1 to 14, on both outer wings between FR 40 and FR 47 
by cold-working. The modification includes related investigative 
actions and applicable corrective actions. The related investigative 
actions include a rotating probe test of the fastener holes for cracks 
and checking the hole diameter for certain diameters. The corrective 
action is repair.
    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-2018-
0025.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We considered the comment received. FedEx supported 
the NPRM.

Conclusion

    We reviewed the relevant data, considered 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 
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 Service Bulletin A310-57-2105, Revision 00, dated 
November 23, 2016. The service information describes procedures for a 
modification of the fastener holes at rib 1, stiffeners 1 to 14, on 
both outer wings between FR 40 and FR 47 by cold-working and includes 
related investigative actions and corrective actions. This service 
information is reasonably available because the

[[Page 24398]]

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 13 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                                 Estimated Costs

    We estimate the following costs to do any necessary repair that 
will be required based on the results of the inspection. We have no way 
of determining the number of aircraft that might need this repair:

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.
