Discussion \n\n\n\tThe FAA issued AD 2020-03-12, Amendment 39-19837 (85 FR 7863, February 12, 2020) (''AD 2020-03-12''), which applied to all Airbus SAS Model A350-941 and -1041 airplanes. AD 2020-03-12 required revising the existing AFM to define a liquid-prohibited zone in the flight deck and provide procedures following liquid spillage on the center pedestal. The FAA issued AD 2020-03-12 to address the potential for dual-engine uncommanded engine inflight shutdown (IFSD), possibly resulting in a forced landing with consequent damage to the airplane and injury to occupants. \n\nActions Since AD 2020-03-12 Was Issued \n\n\n\tSince the FAA issued AD 2020-03-12, Airbus developed mod 116010, introducing a removable cover for the ICP, which protects the ICP completely, including engine master levers, thumbwheels, and rotary knob, and provided modification instructions. Airbus also published a new AFM temporary revision (TR) defining a liquid-prohibited zone inthe cockpit, procedures for ICP removable cover use, and the procedures to be followed in the case of inadvertent liquid spillage on the center pedestal. The FAA has determined that the removable ICP cover must be installed and the existing AFM must be revised to include these new procedures. \n\tThe EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020-0090, dated April 20, 2020 (''EASA AD 2020-0090'') (also referred to as the Mandatory Continuing Airworthiness Information, or ''the MCAI''), to correct an unsafe condition for certain Airbus SAS Model A350-941 and -1041 airplanes. EASA AD 2020-0090 supersedes EASA Emergency AD 2020-0020-E, dated February 5, 2020, corrected February 6, 2020 (which corresponds to FAA AD 2020-03-12). \n\tThis AD was prompted by two reports of abnormal operation of the components of the ENG START panel or Electronic Centralized Aircraft Monitoring (ECAM) Control Panel (ECP) due to liquid spillage in the system, and the subsequent uncommanded engine IFSD of one engine in each case. This AD was also prompted by the FAA's determination that a removable integrated control panel (ICP) cover must be installed to prevent damage from spillage and that the existing AFM must be revised. The FAA is issuing this AD to address the potential for dual-engine IFSD, possibly resulting in a forced landing with consequent damage to the airplane and injury to occupants. See the MCAI for additional background information. \n\nExplanation of Retained Requirements \n\n\n\tAlthough this AD does not explicitly restate the requirements of AD 2020-03-12, this AD retains all of the requirements of AD 2020-03-12. Those requirements are referenced in EASA AD 2020-0090, which, in turn, is referenced in paragraph (g) of this AD. \n\n((Page 30602)) \n\nRelated IBR Material Under 1 CFR Part 51 \n\n\n\tEASA AD 2020-0090 describes procedures for installation of the ICP removable cover in the cockpit and amendment of the AFM to define a liquid-prohibited zone in the cockpit, provide procedures for ICP removable cover use, and provide procedures following liquid spillage on the center pedestal. 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. \n\nFAA's Determination \n\n\n\tThis product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to the FAA's 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 FAA has 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. \n\nRequirements of This AD \n\n\n\tThis AD requires accomplishing the actions specified in EASA AD 2020-0090 describedpreviously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD. \n\nExplanation of Required Compliance Information \n\n\n\tIn 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, in EASA AD 2020- 0090 is incorporated by reference in this AD. This AD, therefore, requires compliance with EASA AD 2020-0090 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 2020-0090 that is required for compliance with EASA AD 2020-0090 is available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-0452. \n\nInterim Action \n\n\n\tThe FAA considers this AD interim action. If final action is later identified, the FAA might consider further rulemaking then. \n\nFAA's Justification and Determination of the Effective Date \n\n\n\tAn unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because abnormal operation of the components of the ENG START panel or ECP due to liquid spillage in the system could result in dual-engine IFSD, possibly resulting in a forced landing with consequent damage to the airplane and injury to occupants. Therefore, the FAA finds good cause that notice and opportunity for prior public comment are impracticable. In addition, for the reasons stated above, the FAA finds that good cause exists for making this amendment effective in less than 30 days. \n\nRegulatory Flexibility Act (RFA) \n\n\n\tThe requirements of the RFA do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without notice and comment, RFA analysis is not required. \n\nComments Invited \n\n\n\tThis 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-2020-0452; Product Identifier 2020-NM-062-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. \n\tThe FAA will post all comments received, without change, to https://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. \n\nCosts of Compliance \n\n\n\tThe FAA estimates that this AD affects 13 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: \n\n\n\tEstimated Costs for Required Actions ---------------------------------------------------------------------------------------------------------------- \n\tCostper Cost on U.S. \n\tActions Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Retained actions from AD 2020-03-12... 1 work-hour x $85 per $0 $85 $1,105 \n\thour = $85. New actions........................... 2 work-hours x $85 per * 0 170 2,210 \n\thour = $170. ---------------------------------------------------------------------------------------------------------------- \n* The FAA has received no definitive data regarding cost estimates for these parts.\n\n\n\n\tAccording 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 our cost estimate. \n\nAuthority for This Rulemaking \n\n\n\tTitle 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. \n\tThe FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: ''General requirements.'' Under \n\n((Page 30603)) \n\nthat 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. \n\nRegulatory Findings \n\n\n\tThe FAA 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. \n\tFor the reasons discussed above, I certify that this AD: \n\t(1) Is not a ''significant regulatory action'' under Executive Order 12866; and \n\t(2) Will not affect intrastate aviation in Alaska. \n\nList of Subjects in 14 CFR Part 39 \n\n\n\tAir transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
