    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 SAS Model A318, A319, and A320 series airplanes, and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -253N, and -271N airplanes. The NPRM published in the Federal Register on April 2, 2018 (83 FR 13885). The NPRM was prompted by a revision of an airworthiness limitations document that specifies more restrictive maintenance requirements and airworthiness limitations. The NPRM proposed to require revising the maintenance or inspection program, as applicable, to incorporate the specified maintenance requirements and airworthiness limitations.

    We are 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.

    The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2017-0170, dated September 7, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Airbus SAS Model A318, A319, and A320 series airplanes, and Model A321-111, -211, -212, -213, -231, -232, -251N, -253N, and -271N airplanes. The MCAI states:

    The System Equipment Maintenance Requirements (SEMR) for Airbus A320 family aeroplanes, which are approved by EASA, are currently defined and published in the Airbus A318/A319/A320/A321 Airworthiness Limitations Section (ALS) Part 4 document. These instructions have been identified as mandatory for continued airworthiness.

    Failure to accomplish these instructions could result in an unsafe condition.

    Previously, EASA issued AD 2016-0093 [which corresponds to FAA AD 2017-19-24, Amendment 39-19054 (82 FR 44900, September 27, 2017) (“AD 2017-19-24”),] to require accomplishment of all maintenance tasks as described in ALS Part 4 at Revision 03. ALS Part 4 Revision 04 was not mandated because no significant changes were introduced with this Revision. The new ALS Part 4 Revision 05 (hereafter referred to as `the ALS' in this [EASA] AD) includes new and/or more restrictive requirements and extends the applicability to model A320-251N, A320-271N, A321-251N, A321-253N and A321-271N aeroplanes.

    For the reason described above, this [EASA] AD retains the requirements of EASA AD 2016-0093, which is superseded, and requires accomplishment of all tasks as described in the ALS.

    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-2018-0168.

    Comments

    We gave the public the opportunity to participate in developing this final rule. We have considered the comment received. United Airlines indicated that they had no objection to the NPRM.

    Explanation of Changes to Applicability

    We have revised the applicability of this AD to identify model designations as published in the most recent type certificate data sheet for the affected models.Start Printed Page 39582

    Conclusion

    We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this final rule 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 addressing 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 SAS has issued Airbus SAS A318/A319/A320/A321 Airworthiness Limitations Section (ALS) Part 4, “System Equipment Maintenance Requirements (SEMR),” Revision 05, dated April 6, 2017. This service information describes preventive maintenance requirements and includes updated inspections and intervals to be incorporated into the maintenance or inspection program. 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 1,133 airplanes of U.S. registry.

    We estimate the following costs to comply with this AD:

    We have determined that revising the maintenance or inspection program takes an average of 90 work-hours per operator, although this figure may vary from operator to operator. In the past, we have estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), we have determined that a per-operator estimate is more accurate than a per-airplane estimate. Therefore, we estimate the total cost per operator to be $7,650 (90 work-hours × $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.

    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 and associated appliances to the Director of the System Oversight Division.

    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) 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.
