 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2017-0908; Product Identifier 2017-NM-103-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 all Dassault Aviation Model FAN JET FALCON, FAN JET FALCON SERIES D, E, F, and G airplanes; and certain Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. This proposed AD was prompted by reports of the collapse of the main landing gear on touchdown. This proposed AD would require an electrical modification of the landing gear sequence logic. 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:*

                    ( print page 49152) Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2017-0130, dated July 26, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for all Dassault Aviation Model FAN JET FALCON, FAN JET FALCON SERIES D, E, F, and G airplanes; and certain Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. The MCAI states: An incident occurred in January 2016 on a Falcon 20-5 aeroplane where, upon touchdown, one main landing gear (MLG) collapsed, due to a sequence anomaly. This condition, if not corrected, could lead to additional events of MLG collapse, possibly resulting in damage to the aeroplane and injury to the occupants. Prompted by previous similar events, Dassault developed a modification, ensuring that hydraulic pressure of circuit #1 of the landing gear actuators is maintained after the extension sequence is completed. As a result, in the unlikely case of having one of the legs not properly mechanically locked down, the pressure maintained in the landing gear bracing devices will prevent landing gear from collapsing. Dassault published Service Bulletin (SB) F20-676 in 1981 (later revised in 1998) which contains the necessary instructions to modify in-service aeroplanes. For the reasons described above, this [EASA] AD requires an electrical modification of the landing gear sequence logic. You may examine the MCAI in the AD docket on the Internet at

                     by searching for and locating Docket No. FAA-2017-0908. Related Service Information Under 1 CFR Part 51 Dassault Aviation has issued Dassault Service Bulletin F20-676, Revision 1, dated March 4, 1998. This service information describes an electrical modification of the MLG sequence logic to prevent landing gear collapse on touchdown. 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

                     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 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 308 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.
