RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).
 ACTION: Final rule.
 SUMMARY: We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by a review showing that inadequate clearance may exist between certain electrical wiring and nearby structures. This AD requires an inspection of certain electrical wiring bundles and feeders, modifications, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.
 DATES: This AD is effective November 6, 2017. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of November 6, 2017.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Dassault Aviation Model FALCON 7X airplanes. The NPRM published in the 
                    **Federal Register**
                     on June 12, 2017 (82 FR 26867) (“the NPRM”). The NPRM was prompted by a review showing that inadequate clearance may exist between certain electrical wiring and nearby structures. The NPRM proposed to require an inspection of certain electrical wiring bundles and feeders, modifications, and corrective actions if necessary. We are issuing this AD to detect and correct inadequate clearances between electrical wiring and nearby structures, which could lead to interference or contact with a structure and cause an electrical short circuit or fluid leakage. This could result in the loss of several functions essential for safe flight. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2016-0230, dated November 21, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Dassault Aviation Model FALCON 7X airplanes. The MCAI states: A review of the wiring and tubing lay-out showed that there may be low clearance between electrical wiring and nearby structure. Although no in-service incident has been reported, the minimum clearances could deteriorate over time. This condition, if not detected and corrected, could lead to interference or contact with structure, provoking an electrical short circuit or fluid leakage, possibly resulting in loss of several functions essential for safe flight. To initially address this potential unsafe condition, [Dassault Aviation] DA developed some interim modifications (mod) addressing the risk of short circuit and fluid leakage, and EASA issued AD 2010-0029 (later revised) [which corresponds to FAA AD 2011-14-04, Amendment 39-16739 (76 FR 39256, July 6, 2011) (“AD 2011-14-04”)] to require embodiment of those modifications in-service. Since EASA AD 2010-0029R1 was issued, DA developed another set of modifications, available for in-service application through Service Bulletin (SB) F7X-056, which are considered the final solutions for this unsafe condition. For the reasons described above, this [EASA] AD requires a one-time [general visual] inspection [for worn or damaged wiring or connectors due to inadequate clearance between wiring and nearby structures] of the affected electrical wiring and, depending on findings, corrective action(s) and modification of the aeroplane. Corrective actions include modifying the clamping and routing; adding new brackets, clamps, and cable protections; replacing damaged parts; and improving connections using lock wires. You may examine the MCAI in the AD docket on the Internet at 
                    *http://www.regulations.gov*
                     by searching for and locating Docket No. FAA-2017-0532. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial 
                    ( print page 45702)
                    changes. We have determined that these minor changes: Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
                Do not add any additional burden upon the public than was already proposed in the NPRM. Related Service Information Under 1 CFR Part 51 Dassault Aviation has issued Service Bulletin 7X-056, Revision 1, dated July 20, 2016. This service information describes procedures for an inspection of certain electrical wiring (wiring bundles and feeders), corrective actions, and modification of the airplane. 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. Costs of Compliance We estimate that this AD affects 51 airplanes of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs

 We have received no definitive data that will enable us to provide cost estimates for the on-condition actions specified in this AD. 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.
