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 nonsustaining 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 https:// 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 product Action Labor cost Parts cost Install protective sleeves ............................ 10 work-hours × $85 per hour = $850 ...... Negligible ................. sradovich on DSK3GMQ082PROD with RULES Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety.

This condition, if not detected and corrected, could lead to hidden sensor signal drift (at flap station 3) which, in combination with an independent failure of a flap down drive disconnect, might lead to in-flight detachment of the outer flap surface, possibly resulting in damage to the aeroplane, and/or injury to persons on the ground. Airbus determined that the SPPU calibration test can highlight all hidden faults, but this test is only scheduled after removal/installation of the equipment. Consequently, to address this potential unsafe condition, Airbus issued the SB [Service Bulletin A350–27–P021, dated February 13, 2018], providing instructions to accomplish the SPPU calibration test at regular intervals. For the reason described above, this [EASA] AD requires repetitive SPPU calibration test and, depending on findings, accomplishment of applicable corrective action(s) [applying corresponding airplane fault isolation]. Pending the results of the on-going investigation, this [EASA] AD is still considered to be an interim measure and further [EASA] AD action may follow.

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 https://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

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.
