    AGENCY:

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

    ACTION:

    Final rule.

    SUMMARY:

    The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This AD was prompted by a determination that ram air turbine (RAT) performance may be below the expected (certificated) level when the landing gear is extended. This AD requires installing flight control and guidance system (FCGS) software (SW) X11 Standard (STD), as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

    DATES:

    This AD is effective March 12, 2020.

    The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of March 12, 2020.

    SUPPLEMENTARY INFORMATION:

    Discussion

    The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019-0203, dated August 20, 2019 (“EASA AD 2019-0203”) (also referred to as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Airbus SAS Model A350-941 airplanes.

    The FAA 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 A350-941 airplanes. The NPRM published in the Federal Register on October 30, 2019 (84 FR 58073). The NPRM was prompted by a determination that RAT performance may be below the expected (certificated) level when the landing gear is extended. The NPRM proposed to require installing FCGS SW X11 STD.

    The FAA is issuing this AD to address this condition, which, if not corrected, could lead to partial or total loss of RAT electrical power generation when the RAT is deployed in an emergency situation, possibly resulting in reduced control 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 FAA has considered the comment received. The Air Line Pilots Association, International (ALPA) stated that it supports the NPRM.

    Conclusion

    The FAA 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. The FAA has 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 IBR Material Under 1 CFR Part 51

    EASA AD 2019-0203 describes procedures for installing FCGS SW X11 STD. 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.

    Interim Action

    The FAA considers this AD interim action. If final action is later identified, the FAA might consider further rulemaking then.

    Costs of Compliance

    The FAA estimates that this AD affects 13 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:

    Estimated Costs for Required Actions

    Labor costParts costCost per productCost on U.S. operators
    8 work-hours × $85 per hour = $680$4,650$5,330$69,290

    According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all known costs in the cost estimate.

    Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, Start Printed Page 6748section 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.

    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) 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.
