Airworthiness Directives; Bombardier, Inc., Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting 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 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 AD requires 
repetitive inspections for fuel leakage at the engine and APU fuel 
pumps, and related investigative and corrective actions if necessary. 
We are issuing this AD to address the unsafe condition on these 
products.

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-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) 
airplanes. The NPRM published in the Federal Register on June 2, 2017 
(82 FR 25556) (``the NPRM''). The NPRM was prompted by reports of fuel 
leaks in the engine and APU EFP cartridge/canister electrical 
connectors and conduits. The NPRM proposed to require repetitive 
inspections for fuel leakage at the engine and APU fuel pumps, and 
related investigative and corrective actions if necessary. We are 
issuing this AD to detect and correct fuel leaks in certain fuel pumps 
to remove a potential fuel ignition hazard.
    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:


[[Page 49499]]


    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 a possible fuel leak 
from the 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 Bulletin] 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.

    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.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM and 
the FAA's response.
    Request To Delay Issuance Until the Release of New Service 
Information

    Bombardier, Inc., indicated its intent to revise Bombardier Service 
Bulletin 604-28-022, dated October 19, 2015; and Bombardier Service 
Bulletin 605-28-010, dated October 19, 2015. Bombardier, Inc., stated 
that these revisions will change the inspection instructions. 
Bombardier, Inc., further added that it plans to publish new service 
information to introduce similar inspections on Model CL-650 airplanes.
    We infer that Bombardier, Inc., is requesting that we delay the 
issuance of this final rule until after the revised service information 
is released and then refer to the revised service information. We 
disagree with the commenter's request. We do not consider that delaying 
this action until release of the planned service information is 
warranted since the service information incorporated by reference in 
this AD adequately addresses the unsafe condition. We might consider 
additional rulemaking once the revised service information is released, 
or if new service information is issued for Model CL-650 airplanes, 
which are not included in the applicability of this AD. We have not 
changed this AD in this regard.

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 604-28-022, dated 
October 19, 2015; and Service Bulletin 605-28-010, dated October 19, 
2015. This service information describes procedures for repetitive 
general visual inspections for fuel leakage at the engine and APU fuel 
pumps, 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.

Costs of Compliance

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

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 required inspection. We have no way of determining the number of 
aircraft that might need these replacements:

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


[[Page 49500]]

    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 AD.
    According to the manufacturer, some of the costs of this 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.
    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.
