Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2016–32R1, dated October 12, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc., Model CL– 600–2B16 (CL–601–3A, CL–601–3R, and CL–604 variants) airplanes. The MCAI states: Fuel leaks have been reported in the engine and auxiliary power unit (APU) electrical fuel pump (EFP) cartridge/canister electrical connectors and conduits on production aeroplanes. Initially, Bombardier had determined that the subject discrepancy was limited to the new pump canister installations on 24 production aeroplanes. Bombardier also reported the possibility of cut insulation on the electric harness wires of the newly installed canister housing assemblies. Emergency [Canadian] AD CF–2014–17 [which corresponds to FAA AD 2014–15–17, Amendment 39–17919 (79 FR 44268, July 31, 2014)] was issued to limit landing light operation on-ground in order to address a potential fire hazard as result of possible fuel leak from APU, EFP electrical conduit in the landing light compartment. In addition, [Canadian] AD CF–2014–21 [which corresponds to FAA AD 2014–20–01, Amendment 39–17974 (79 FR 59640, October 3, 2014), superseded by FAA AD 2016–10– 10, Amendment 39–18521 (81 FR 31497, May 19, 2016)(‘‘AD 2016–10–10’’)] was issued to mandate removal of then identified 24 discrepant EFP canister assemblies from service. Bombardier has recently determined that the subject fuel leaks may not be limited to the 24 units affected by [Canadian] AD CF– 2014–21 [(AD 2016–10–10)], but may potentially affect other in-service [Bombardier Model] CL–600–2B16 aeroplanes. Until such time that a final fix for the fuel leak problem is realized, Bombardier as an interim mitigating action, has issued [Service Bulletins] SB 604–28–022 and SB 605–28–010 that introduces [a] repeat [general visual] inspection and if required, PO 00000 Frm 00019 Fmt 4702 Sfmt 4702 25557 rectification [related investigative and corrective actions] of subject fuel leaks on affected aeroplanes. [Canadian] AD CF– 2016–32 was issued on 29 September 2016 to mandate compliance with applicable Bombardier SBs, to mitigate any potential safety hazard resulting from fuel leaks. Revision 1 of this [Canadian] AD is being issued to correct a typographic error in paragraph B.1. of the [Canadian AD] Corrective Actions. Related investigative actions involve, for certain airplanes, further inspections for fuel leakage. Corrective actions involve repair, and for certain other airplanes, those actions could include replacing O-rings, and replacing the fuel cartridge. 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– 0521. Related Service Information Under 1 CFR Part 51 Bombardier, Inc., has issued the following service bulletins: • Bombardier Service Bulletin 604– 28–022, dated October 19, 2015; and • Bombardier Service Bulletin 605– 28–010, dated October 19, 2015. The service information describes procedures for repetitive general visual inspections, and related investigative and corrective actions if necessary. These documents are distinct since they apply to airplanes in different configurations. 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. 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 the same type design. Costs of Compliance We estimate that this proposed AD affects 121 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: E:\FR\FM\02JNP1.SGM 02JNP1 25558 Federal Register / Vol. 82, No. 105 / Friday, June 2, 2017 / Proposed Rules ESTIMATED COSTS Action Labor cost General Visual Inspection ............................... 1 work-hour × $85 per hour = $85 ................. For Model CL–600–2B16 airplanes, having serial numbers 5701 through 5955 inclusive, 5957, 5960 through 5966 inclusive, 5968 through 5971 inclusive, Cost per product Parts cost and 5981, we estimate the following costs to do any necessary replacements that would be required based on the results of the proposed inspection. We $0 Cost on U.S. operators $85 $10,285 have no way of determining the number of aircraft that might need these replacements: ON-CONDITION COSTS Action Labor cost Replace O-Ring in Affected Pump ............................... Replace Cartridge in Affected Pump ............................ 3 work-hours × $85 per hour = $255 ........................... 2 work-hours × $85 per hour = $170 ........................... For Model CL–600–2B16 airplanes having serial numbers 5301 through 5665 inclusive, we have received no definitive data that would enable us to provide cost estimates for the oncondition actions specified in this proposed AD. According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. nlaroche on DSK30NT082PROD with PROPOSALS 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 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 VerDate Sep<11>2014 13:14 Jun 01, 2017 Jkt 241001 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.

Airworthiness Directives; Bombardier, Inc., Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Bombardier, Inc., Model CL-600-2B16 (CL-601-3A, CL-601-3R, and 
CL-604 Variants) airplanes. This proposed AD was prompted by reports of 
fuel leaks in the engine and auxiliary power unit (APU) electrical fuel 
pump (EFP) cartridge/canister electrical connectors and conduits. This

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-32R1, dated October 12, 2016 (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-
2B16 (CL-601-3A, CL-601-3R, and CL-604 variants) airplanes. The MCAI 
states:

    Fuel leaks have been reported in the engine and auxiliary power 
unit (APU) electrical fuel pump (EFP) cartridge/canister electrical 
connectors and conduits on production aeroplanes. Initially, 
Bombardier had determined that the subject discrepancy was limited 
to the new pump canister installations on 24 production aeroplanes. 
Bombardier also reported the possibility of cut insulation on the 
electric harness wires of the newly installed canister housing 
assemblies.
    Emergency [Canadian] AD CF-2014-17 [which corresponds to FAA AD 
2014-15-17, Amendment 39-17919 (79 FR 44268, July 31, 2014)] was 
issued to limit landing light operation on-ground in order to 
address a potential fire hazard as result of possible fuel leak from 
APU, EFP electrical conduit in the landing light compartment. In 
addition, [Canadian] AD CF-2014-21 [which corresponds to FAA AD 
2014-20-01, Amendment 39-17974 (79 FR 59640, October 3, 2014), 
superseded by FAA AD 2016-10-10, Amendment 39-18521 (81 FR 31497, 
May 19, 2016)(``AD 2016-10-10'')] was issued to mandate removal of 
then identified 24 discrepant EFP canister assemblies from service.
    Bombardier has recently determined that the subject fuel leaks 
may not be limited to the 24 units affected by [Canadian] AD CF-
2014-21 [(AD 2016-10-10)], but may potentially affect other in-
service [Bombardier Model] CL-600-2B16 aeroplanes. Until such time 
that a final fix for the fuel leak problem is realized, Bombardier 
as an interim mitigating action, has issued [Service Bulletins] SB 
604-28-022 and SB 605-28-010 that introduces [a] repeat [general 
visual] inspection and if required, rectification [related 
investigative and corrective actions] of subject fuel leaks on 
affected aeroplanes. [Canadian] AD CF-2016-32 was issued on 29 
September 2016 to mandate compliance with applicable Bombardier SBs, 
to mitigate any potential safety hazard resulting from fuel leaks.
    Revision 1 of this [Canadian] AD is being issued to correct a 
typographic error in paragraph B.1. of the [Canadian AD] Corrective 
Actions.

    Related investigative actions involve, for certain airplanes, 
further inspections for fuel leakage. Corrective actions involve 
repair, and for certain other airplanes, those actions could include 
replacing O-rings, and replacing the fuel cartridge. 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-2017-0521.

Related Service Information Under 1 CFR Part 51

    Bombardier, Inc., has issued the following service bulletins:
     Bombardier Service Bulletin 604-28-022, dated October 19, 
2015; and
     Bombardier Service Bulletin 605-28-010, dated October 19, 
2015.
    The service information describes procedures for repetitive general 
visual inspections, and related investigative and corrective actions if 
necessary. These documents are distinct since they apply to airplanes 
in different configurations. 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.

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 the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects 121 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

[[Page 25558]]



                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.

    For Model CL-600-2B16 airplanes, having serial numbers 5701 through 
5955 inclusive, 5957, 5960 through 5966 inclusive, 5968 through 5971 
inclusive, and 5981, we estimate the following costs to do any 
necessary replacements that would be required based on the results of 
the proposed inspection. We have no way of determining the number of 
aircraft that might need these replacements:

----------------------------------------------------------------------------------------------------------------

    For Model CL-600-2B16 airplanes having serial numbers 5301 through 
5665 inclusive, we have received no definitive data that would enable 
us to provide cost estimates for the on-condition actions specified in 
this proposed AD.
    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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 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.
