 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 MYSTERE-FALCON 50 airplanes. This AD was prompted by a report of an untimely and intermittent indication of slat activity due to chafing of the electrical wiring under the glare shield and behind the flight deck front panel. This AD requires installing two protective plates between the electrical wiring under the glare shield and the engine fire pull handles. We are issuing this AD to prevent chafing of the electrical 
                        ( print page 5035)
                        wiring, which could result in a short circuit and generation of smoke in the cockpit, potential loss of several functions essential for safe flight, and consequent reduced controllability of the airplane.
 DATES: This AD becomes effective March 6, 2015. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of March 6, 2015.

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 MYSTERE-FALCON 50 airplanes. The NPRM published in the 
                    **Federal Register**
                     on August 12, 2014 (79 FR 47031). The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014-0024, dated January 23, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition on certain Dassault Aviation Model MYSTERE-FALCON 50 airplanes. The MCAI states: One operator experienced an untimely and intermittent indication of slat activity on his aeroplane. The results of the subsequent investigation revealed that electrical wiring under the glare shield and behind the flight deck front panel was chafing with hardware and was short-circuited to ground. This situation may have resulted from an incorrect installation of the wiring during a previous maintenance action in the area. A design review identified a lack of protection of the affected electrical wiring bundle, which would have prevented damage caused by chafing with aeroplane structural parts. This condition, if not corrected, might lead to an electrical short circuit and generation of smoke, possibly affecting operation of systems and resulting in reduced control of the aeroplane. To address this potential unsafe condition, Dassault Aviation issued [service bulletin] SB F50-530, providing instructions for installation of a protective plate on the electrical wiring. For the reasons described above, this [EASA] AD requires modification of the aeroplane by installing a protective plate on the electrical wiring. You may examine the MCAI in the AD docket on the Internet at 
                    *http://www.regulations.gov/​#!documentDetail;​D=​FAA-2014-0527-0002.* Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 47031, August 12, 2014) 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, with minor editorial changes. We have determined that these minor changes: Are consistent with the intent that was proposed in the NPRM (79 FR 47031, August 12, 2014) for correcting the unsafe condition; and
                Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 47031, August 12, 2014). Related Service Information We reviewed Dassault Service Bulletin F50-530, dated November 12, 2013. The service information describes procedures for installing two protective plates between the electrical wiring under the glare shield and the engine fire pull handles. You can find this information at 
                    *http://www.regulations.gov*
                     by searching for and locating Docket No. FAA-2014-0527. Costs of Compliance We estimate that this AD affects 250 airplanes of U.S. registry. We estimate the following costs to comply with this 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. 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
                    ( print page 5036) 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. Examining the AD Docket You may examine the AD docket on the Internet at
