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 Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), Model CL-600- 2D15 (Regional Jet Series 705), Model CL-600-2D24 (Regional Jet Series 900), and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. The NPRM published in the Federal Register on September 13, 2017 (82 FR 42953) (``the NPRM''). The NPRM was prompted by a report of a smoke-in- cabin event due to a non-sustaining electrical fire. The NPRM proposed to require installation of protective sleeves on the bonding jumper wires of affected galleys and lavatories. We are issuing this AD to prevent an electrical short of a bonding jumper wire that may result in in-flight smoke or fire events, as well as failure of avionics equipment, due to possible water spray or leakage from a damaged water supply line. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF-2016-20R1, dated February 3, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet Series 705), Model CL-600-2D24 (Regional Jet Series 900), and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. The MCAI states: A CRJ900 aeroplane reported a smoke in cabin event due to a non- sustaining electrical fire. The source of smoke was traced to a burnt heated water supply line behind the #2 Galley. The surrounding insulation was also found burnt. The root cause of this electrical fire was an electrical short between an un-insulated bonding jumper and a terminal block carrying 115 volts AC. The circuit resistance was high enough and the circuit breakers that protect the wiring did not trip open. Electrical short of a bonding jumper may result in in-flight smoke or fire events as well as failure of avionics equipment due to possible water spray or leakage from a damaged water supply line. The likelihood of this happening is increased by the removal and installation of the galley or lavatory during maintenance, allowing the bonding jumper to become wedged under the terminal block. * * * * * Revision 1 of this [Canadian] AD is issued to mandate [the installation of protective sleeves on the galley and lavatory bonding jumper wires in accordance with] Bombardier Service Bulletin (SB) 670BA-25-101 Revision B dated 12 January 2017. * * * 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- 0810. Comments We gave the public the opportunity to participate in developing this final rule. We considered the comment received. The Air Line Pilots Association, International supported the NPRM. Conclusion We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial 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 Bombardier, Inc., has issued Service Bulletin 670BA-25-101, Revision B, dated January 12, 2017. The service information describes procedures for installation of protective sleeves on the bonding jumper wires of affected galleys and lavatories. 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 544 airplanes of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Install protective sleeves........ 10 work-hours x $85 Negligible........... $850 $462,400 per hour = $850. ---------------------------------------------------------------------------------------------------------------- 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 [[Page 15047]] 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.
