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-604 Variants) 
airplanes. This proposed AD was prompted by reports of floodlight lamps 
found burned and the corresponding circuit breaker tripped as a result 
of fluid entering the cockpit floodlight fixtures. This proposed AD 
would require installation of a new gasket seal on floodlight fixtures. 
We are proposing this AD to address the unsafe condition on these 
products.

DATES: We must receive comments on this proposed AD by August 6, 2018.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:
    <bullet> Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2016-40, dated December 
15, 2016; and Canadian AD CF-2018-06, dated February 19, 2018; to 
correct an unsafe condition for certain Bombardier, Inc., Model CL-600-
2B16 (CL-604 Variants) airplanes. Canadian AD CF-2016-40 and Canadian 
AD CF-2018-06 are referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI.''

    Canadian AD CF-2016-40 states:
    Several operators have reported a burning odor and smoke 
emanating from the cockpit floodlights. Bombardier Aerospace (BA) 
has determined the cause to be fluid entering into the cockpit 
floodlight fixtures causing short circuits and damage to electrical 
components. If not corrected, this condition may result in a fire in 
the cockpit.
    This [Canadian] AD is issued to mandate the installation of a 
new gasket seal on the floodlight fixture.
    Canadian AD CF-2018-06 states:
    [Canadian] AD CF-2016-40, applicable to Bombardier Inc. model 
CL-600-2B16 (604 [CL-604 Variants serial numbers 5301 through 5665 
inclusive] and 605 [CL-604 Variants serial numbers 5701 through 5988 
inclusive] variants) aeroplanes, was issued to address the potential 
of water penetrating into cockpit floodlight fixtures. A similar 
condition exists on the CL-600-2B16 (650 variant [CL-604 Variants 
serial numbers 6050 through 6070 inclusive]) aeroplanes. This 
condition can cause short circuits and damage to electrical 
components, which may result in a fire in the cockpit.
    This [Canadian] AD mandates the installation of gasket seals on 
the pilot and co-pilot floodlight fixtures to prevent fluid from 
entering them.

    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-2018-
0550.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued the following service information:
    <bullet> Bombardier Service Bulletin 604-33-007, Revision 02, dated 
October 2, 2017.
    <bullet> Bombardier Service Bulletin 605-33-005, Revision 02, dated 
October 2, 2017.
    <bullet> Bombardier Service Bulletin 650-33-001, Revision 03, dated 
October 2, 2017.
    The service information describes procedures to install a new 
gasket seal on floodlight fixtures. These documents are distinct since 
they apply to different configurations of the same airplane model. The 
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 these 
same type design.

Costs of Compliance

    We estimate that this proposed AD affects 123 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
              Labor cost                  Parts cost         Cost per product          Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 2 work-hours x $85 per hour = Up              $0  Up to $170...............  Up to $20,910.
 to $170.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some or all 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 known 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,

[[Page 29063]]

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 proposed 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 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.
