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-604 Variants) airplanes. This 
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 AD requires installation of new 
gasket seals on floodlight fixtures. We are issuing this AD to address 
the unsafe condition on these products.

DATES: This AD is effective November 20, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 20, 
2018.

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-604 Variants) airplanes. The NPRM published in 
the Federal Register on June 22, 2018 (83 FR 29061). The NPRM 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. The NPRM proposed to require installation 
of new gasket seals on floodlight fixtures.
    We are issuing this AD to address fluid entering the cockpit 
floodlight fixtures, which could cause short circuits and damage to 
electrical components, which may result in a fire in the cockpit.
    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.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We received no comments on the NPRM or on the 
determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this final rule 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 addressing 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 has issued the following service information:
     Bombardier Service Bulletin 604-33-007, Revision 02, dated 
October 2, 2017.
     Bombardier Service Bulletin 605-33-005, Revision 02, dated 
October 2, 2017.
     Bombardier Service Bulletin 650-33-001, Revision 03, dated 
October 2, 2017.
    The service information describes procedures to install new gasket 
seals on floodlight fixtures. These documents are distinct since they 
apply to different configurations of the same airplane model. 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 123 airplanes of U.S. registry. We 
estimate the following costs to comply with this 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 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,

[[Page 52122]]

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 and 
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

    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.
