SUPPLEMENTARY INFORMATION:  Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018-0154, dated July 19, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Airbus SAS Model A350-941 and -1041 airplanes. The MCAI states: During an inspection on the A350 final assembly line, after engine installation, protective caps were found still in place on fire extinguishing lines at engine zone 1 and zone 3. Further investigations indicated that this failure of removing them, as the standard instructions specify, may have occurred on other aeroplanes. Airbus has identified the [manufacturer serial numbers] MSN that may be affected. This condition, if not detected and corrected, could, in case of an engine fire, prevent extinguishing that engine fire, possibly resulting in reduced control of the aeroplane. To address this unsafe condition, Airbus published the [Alert Operators Transmission A26P004-18, Revision 00, dated June 26, 2018] AOT to provide inspection instructions. For the reasons described above, this [EASA] AD requires a one-time detailed inspection (DET) of the affected areas and, depending on findings, [corrective action]. Corrective action includes removal of the protective caps and cleaning out any melted protective caps. You may examine the MCAI on the internet at 
                    *http://www.regulations.gov*
                     by searching for and locating Docket No. FAA-2018-0766. Related Service Information Under 1 CFR Part 51 Airbus SAS has issued Alert Operators Transmission (AOT) A26P004-18, Revision 00, dated June 26, 2018. This service information describes procedures for inspection for the presence of protective caps on fire extinguishing lines, and corrective actions. 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. 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 our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we 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 the service information described previously. FAA's Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because protective caps still in place on fire extinguishing lines in certain areas of the engines could, in case of an engine fire, prevent extinguishing that engine fire, possibly resulting in reduced control of the airplane. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite 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-2018-0766; Product Identifier 2018-NM-111-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD based on those comments. We will post all comments we receive, without change, to 
                    *http://www.regulations.gov,*
                     including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. Costs of Compliance We estimate that this AD affects 11 airplanes of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs for Required Actions

 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.
