Airworthiness Directives; Bombardier, Inc. Airplanes

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

ACTION: Final rule; request for comments.

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

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 requires repetitive inspections for any 
fuel leak in the right-hand landing lights compartment, and related 
investigative and corrective actions if necessary. This AD also 
provides for an optional replacement of the connector of the fuel boost 
pump canister of the auxiliary power unit (APU), which terminates the 
repetitive inspections. This AD was prompted by a report of fuel leaks 
in the connector cavity of the APU fuel boost pump canister and at the 
electrical conduit connection of the APU fuel boost pump in the right-
hand landing lights compartment. We are issuing this AD to detect and 
correct fuel leaks in the right-hand landing lights compartment, which, 
in combination with the heat generated by the taxi lights and landing 
lights on the ground reaching the auto-ignition temperature of the 
fuel, could result in ignition of any fuel or fumes present in the 
right-hand landing lights compartment.

DATES: This AD becomes effective October 20, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 20, 
2014.
    We must receive comments on this AD by November 17, 2014.

SUPPLEMENTARY INFORMATION:

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-21, dated July 10, 2014 (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:

    Bombardier Inc. has discovered fuel leakage in the auxiliary 
power unit (APU) fuel Boost Pump (BP) canister connector cavity. On 
some of those aeroplanes, leakage was also noticed at the APU fuel 
BP electrical conduit connection in the right hand landing light 
compartment. The root cause of the subject fuel leak is identified 
to be the improper length of the female connector keyway located in 
the fuel BP canister, causing a shift of the electrical harness and 
its seals.
    Available data indicates that on a hot day, due to the heat 
generated by the taxi light and/or landing lights on the ground, 
temperature in the landing light compartment can reach the fuel auto 
ignition temperature. Therefore, presence of any fuel in the right 
hand landing light compartment is considered to be a safety hazard 
[fuel or fumes present in the right-hand landing lights compartment 
might ignite] that warrants mitigating action.
    In order to help mitigate the potential safety hazard 
precipitated by any fuel leakage in the right hand landing light 
compartment, Bombardier Inc., has revised the Aircraft Flight Manual 
(AFM) through Temporary Revisions (TRs) 604/38 and 605/20 dated 16 
June 2014 to restrict the operation of Taxi and Landing lights on 
the ground. Transport Canada issued Emergency [Canadian] AD CF-2014-
17 [(http://wwwapps3.tc.gc.ca/Saf-Sec-Sur/2/cawis-swimn/attachment.asp?aiid=CF-2014-17&revid=0&cntr=CF&file=CFCF-2014-17.pdf&type=PDE), which corresponds to FAA AD 2014-15-17, Amendment 
39-17919 (79 FR 44268, July 31, 2014)] to mandate incorporation of 
the above AFM TRs.
    To address the root cause of the subject fuel leakage from the 
APU fuel boost pump canister wiring conduit, Bombardier Inc. issued 
Alert Service Bulletin (ASB) A605-28-008 that requires periodic 
[repetitive general visual] inspection[s] for fuel leaks and 
[applicable related investigative and corrective actions and] 
eventual the replacement of the discrepant fuel BP canister 
connectors [including related investigative and corrective actions] 
on affected aeroplanes. The ASB has been revised to include an 
additional inspection of the new connector wiring for damage and 
this [Canadian] AD is issued to mandate the compliance with ASB 
A605-28-008 Revision 2 requirements.

Related investigative actions include doing a general visual inspection 
for any fuel leak in the wiring conduit of the APU fuel boost pump in 
the right-hand landing lights compartment; a detailed inspection for 
damage of the O-rings of the fuel pump cartridge; and a detailed 
inspection of the wires under the wiring insulation sleeve of the new 
connector for cuts. Corrective actions include installing new packings 
on the APU fuel pump cartridge, replacing the connector on the APU fuel 
pump canister, and replacing wiring and O-rings if certain conditions 
are found. You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2014-
0650.

Relevant Service Information

    Bombardier, Inc. has issued Bombardier Alert Service Bulletin A605-
28-008, Revision 02, dated July 9, 2014. The actions described in this 
service information are intended to

[[Page 59641]]

correct the unsafe condition identified in the MCAI.

Other Relevant Rulemaking

    On July 24, 2014, the FAA issued AD 2014-15-17, Amendment 39-17919 
(79 FR 44268, July 31, 2014), for certain Bombardier, Inc. Model CL-
600-2B16 (CL-604 Variant) airplanes. AD 2014-15-17 requires revising 
the airplane flight manual to incorporate temporary revisions that 
introduce additional limitations for operation of taxi and landing 
lights. AD 2014-15-17 requires revising the airplane flight manual only 
for Bombardier, Inc. Model CL-600-2B16 (CL-604 Variant) airplanes, 
serial numbers 5301 through 5665 inclusive, and 5701 and subsequent. 
This AD requires repetitive inspections for any fuel leak in the right-
hand landing lights compartment, and related investigative and 
corrective actions if necessary, for Bombardier, Inc. Model CL-600-2B16 
(CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes, serial numbers 
5906, 5910, 5912, 5917, 5919 through 5932 inclusive, 5934, 5935, 5939, 
5940, 5942, and 5948.

FAA's Determination and Requirements of This 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 issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Differences Between This AD and the MCAI or Service Information

    The MCAI and Bombardier Alert Service Bulletin A605-28-008, 
Revision 02, dated July 9, 2014, do not specify corrective actions if 
any cut is found on the wires or if any damage is found on the O-rings 
during certain related investigative actions. This AD requires that a 
replacement be done using a method approved by the FAA, TCCA, or 
Bombardier, Inc.'s TCCA Design Approval Organization (DAO).

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because fuel 
leaks in the right-hand landing lights compartment, in combination with 
the heat generated by the taxi lights and landing lights on the ground 
reaching the auto-ignition temperature of the fuel, could result in 
ignition of any fuel or fumes present in the right-hand landing lights 
compartment. Therefore, we determined that notice and opportunity for 
public comment before issuing this AD are impracticable and that good 
cause exists for making this amendment effective in fewer than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2014-0650; Directorate 
Identifier 2014-NM-162-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD based on 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Interim Action

    This AD is considered to be interim action. We are currently 
considering requiring a replacement of the connector of the fuel boost 
pump canister of the APU, and applicable related investigative and 
corrective actions, which will constitute terminating action for the 
repetitive inspections required by this AD action. However, the planned 
compliance time for the replacement would allow enough time to provide 
notice and opportunity for prior public comment on the merits of the 
replacement and applicable related investigative and corrective 
actions.

Costs of Compliance

    We estimate that this AD affects 92 airplanes of U.S. registry.
    We also estimate that it will take about 2 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $15,640, or $170 per product.
    In addition, we estimate that any necessary follow-on actions will 
take about 22 work-hours and require parts costing $0, for a cost of 
$1,870 per product. We have no way of determining the number of 
aircraft that might need these actions.
    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.

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.
