 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2017-0909; Product Identifier 2017-NM-081-AD]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Notice of proposed rulemaking (NPRM).
 SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. This proposed AD was prompted by reports of a loose screw on certain slat mechanical stop assemblies, and punctures in certain fuel caps. This proposed AD would require a one-time inspection, and corrective action if necessary. We are proposing this AD to address the unsafe condition on these products.
 DATES: We must receive comments on this proposed AD by December 8, 2017.
 ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: *Federal eRulemaking Portal:*

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2017-0106, dated June 19, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Dassault Aviation Model MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. The MCAI states: On some aeroplanes in-service, the screw of the slat mechanical stop assembly on slat tracks #6, #7 and #8 was found loose. In some cases, a puncture was found in the fuel cap. The results of the technical investigations concluded that the most probable reason for these events was improper installation of the lock washers on the screws during production or maintenance. This condition, if not detected and corrected, could lead to structural damage to the wing front spar, and consequent fuel leakage, possibly resulting in an uncontrolled fire. To address this potential unsafe condition, Dassault issued [Service Bulletin] SB F900-460 Revision 1, SB F900EX-508 Revision 3, SB F2000-433 Revision 1, and SB F2000EX-386 Revision 3 (hereafter collectively referred as `the applicable SB' in this [EASA] AD), as applicable to aeroplane type/model, to provide inspection instructions. For the reasons described above, this [EASA] AD requires a one-time [general visual] inspection of the slat tracks #6, #7 and #8 to verify the tightening torque of the screw and proper lock washer installation and, depending on findings, accomplishment of applicable corrective action(s). Applicable corrective actions include replacement, if necessary. You may examine the MCAI in the AD docket on the Internet at

                Dassault Service Bulletin F2000EX-386, Revision 3, dated February 10, 2017 This service information describes procedures for doing a one-time general visual inspection of the screw on the affected slat tracks, and replacement if necessary. These documents are distinct since they apply to different airplane models. The 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

                     section. FAA's Determination and Requirements of This Proposed AD 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 
                    ( print page 49150)
                    of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of these same type designs. Costs of Compliance We estimate that this proposed AD affects 65 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs

 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 proposed 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation: 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.
