Discussion
The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019-0181, dated July 26, 2019 (``EASA AD 2019-0181'') (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.
This AD was prompted by a report of cracked external lugs of the aluminum cargo door latch fittings in the lower part of the forward and aft cargo doors. The FAA is issuing this AD to address this condition, which, if not detected and corrected, could result in rapid decompression or loss of structural integrity of the airplane. See the MCAI for additional background information.

EASA AD 2019-0181 describes procedures for repetitive detailed inspections of the external lugs of the aluminum cargo door latch fittings for cracks and corrective actions if necessary. Corrective actions include installation of new aluminum cargo door latch fittings. 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.
FAA's Determination
This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to a bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI referenced above. The FAA is issuing this AD because the agency evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.
Requirements of This AD
This AD requires accomplishing the actions specified in EASA AD 2019-0181 described previously, as incorporated by reference, except for any differences identified as exceptionsin the regulatory text of this AD.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD process, the FAA initially worked with Airbus and EASA to develop a process to use certain EASA ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has since coordinated with other manufacturers and civil aviation authorities (CAAs) to use this process. As a result, EASA AD 2019-0181 will be incorporated by reference in the FAA final rule. This AD, therefore, requires compliance with EASA AD 2019-0181 in its entirety, through that incorporation, except for any differences identified as exceptions in the regulatory text of this AD. Using common terms that are the same as the heading of a particular section in the EASA AD does not mean that operators need comply only with that section. For example, where the AD requirement refers to ``all required actions and compliance times,'' compliance with this AD requirement is not limited to the section titled ``Required Action(s) and Compliance Time(s)'' in the EASA AD. Service information specified in EASA AD 2019-0181 that is required for compliance with EASA AD 2019-0181 will be available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2019-0724 after the FAA final rule is published.
FAA's Justification and Determination of the Effective Date
Since there are currently no domestic operators of this product, notice and opportunity for public comment before issuing this AD are unnecessary. In addition, for the reasons stated above, the FAA finds that good cause exists for making this amendment effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight safety, and the FAA did not precede it by notice and opportunity for public comment. The FAA invites you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2019-0724; Product Identifier 2019-NM-134-AD'' at the beginning of your comments. The FAA specifically invites comments on the overall regulatory, economic, environmental, and energy aspects of this AD. The FAA will consider all comments received by the closing date and may amend this AD based on those comments.
The FAA will post all comments received, without change, to http://www.regulations.gov, including any personal information you provide. The FAA will also post a report summarizing each substantive verbal contact received about this AD.
Costs of Compliance
Currently, there are no affected U.S.-registered airplanes. If an affected airplane is imported and placed on the U.S. Register in the future, the following
[[Page 59715]]
are the cost estimates to comply with this AD:
Estimated Costs for Required Actions ------------------------------------------------------------------------
Cost per
Labor cost Parts cost product ------------------------------------------------------------------------ 6 work-hour x $85 per hour = $510..... $0 $510 ------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on- condition actions that would be required based on the results of any required actions. The FAA has no way of determining the number of aircraft that might need these on-condition action:
Estimated Costs of On-Condition Actions ----------------------------------------------------------------------------------------------------------------
Cost per
Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- 49 work-hours x $85 per hour = $4,165......................................... $83,600 $87,765 ----------------------------------------------------------------------------------------------------------------
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, section 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
The FAA has determined that this AD will not have federalism implications under Executive Order 13132. This AD will nothave 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.
