RIN 2120-AA64
Airworthiness Directives; Bombardier, Inc., Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series
100 & 440) airplanes. This proposed AD was prompted by a report that a
fouling condition was found between the generator power cables and the
support brackets of the auxiliary-aft fuel tank during production. This
proposed AD would require a visual inspection of the generator power
cables for damage, installation of protective conduits and edging
grommets, and applicable corrective actions. The FAA is proposing this
AD to address the unsafe condition on these products.
DATES: The FAA must receive comments on this proposed AD by January 16,
2020.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
[[Page 65936]]

Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2019-22, dated May 27, 2019 (referred to after this as the Mandatory
Continuing Airworthiness Information, or ``the MCAI''), to correct an
unsafe condition for certain Bombardier, Inc., Model CL-600-2B19
(Regional Jet Series 100 & 440) airplanes. You may examine the MCAI in
the AD docket on the internet at https://www.regulations.gov by
searching for and locating Docket No. FAA-2019-0877.
This proposed AD was prompted by a report that a fouling condition
was found between the generator power cables and the support brackets
of the auxiliary-aft fuel tank during production. The FAA is proposing
this AD to address damage to the insulation sleeve of the generator
power cables that can potentially cause a short circuit, arcing, and a
malfunction of one or both main generators. See the MCAI for additional
background information.
Related Service Information Under 1 CFR Part 51
Bombardier has issued Service Bulletin 601R-24-131, dated June 28,
2012. This service information describes procedures for visual
inspection of the generator power cables for damage, installation of
protective insulation and edging grommets, and applicable corrective
actions. Corrective actions include repair. 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
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to a bilateral agreement with the State of Design Authority, the FAA
has been notified of the unsafe condition described in the MCAI and
service information referenced above. The FAA is proposing this AD
because the agency evaluated all the relevant information and
determined the unsafe condition described previously is likely to exist
or develop on other products of the same type design.
Proposed Requirements of This NPRM
This proposed AD would require accomplishing the actions specified
in the service information described previously.
Costs of Compliance
The FAA estimates that this proposed AD affects 9 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this
proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
22 work-hours x $85 per hour = $1,870........................ $524 $2,394 $21,546
----------------------------------------------------------------------------------------------------------------
The FAA has received no definitive data that would enable the
agency to provide cost estimates for the on-condition actions specified
in this proposed AD.
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.
The FAA is 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
[[Page 65937]]
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 and associated appliances to the
Director of the System Oversight Division.
Regulatory Findings
The FAA 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) Will not affect intrastate aviation in Alaska, and
(3) 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.
List of Subjects in 14 CFR Part 39
