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-600-1A11 (600), CL-600-2A12
(601), and CL-600-2B16 (601-3A and 601-3R Variants) airplanes. This
proposed AD was prompted by reports of the loss of all air data system
information provided to the flightcrew, which was caused by icing at
high altitudes. This proposed AD would require revising the exisitng
airplane flight manual (AFM) to provide the flightcrew with procedures
for ``Unreliable Airspeed'' that stabilize the airplane's airspeed and
attitude. 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 September
26, 2019.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2018-36, dated December
27, 2018 (referred to after this as the Mandatory Continuing
Airworthiness Information, or ``the MCAI''), to correct an unsafe
condition for certain Bombardier, Inc., Model CL-600-1A11 (600), CL-
600-2A12 (601), and CL-600-2B16 (601-3A and 601-3R Variants) airplanes.
The MCAI states:
A number of in-service incidents have been reported on CL-600-
2C10 aeroplanes regarding the loss of all air data system
information provided to the crew. The air data system information
was recovered as the aeroplanes descended to lower altitudes. An
investigation determined that the root cause in both events was high
altitude icing (ice crystal contamination). If not recognized and
addressed, this condition may affect continued safe flight and
landing.
Due to similarities in the air data systems, similar events
could also occur on Bombardier Inc. CL-600-1A11, CL-600-2A12 and CL-
600-2B16 aeroplanes.
This [Canadian] AD mandates the incorporation of Airplane Flight
Manual (AFM) procedures that will allow the crew to stabilize the
aeroplane's airspeed and attitude for continued safe flight and
landing.
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-2019-
0582.

These documents are distinct since they apply to different airplane
models 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.
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 revising the existing AFM with
procedures for ``Unreliable Airspeed'' in the Emergency Procedures
section of the applicable AFM as described previously.
Costs of Compliance
The FAA estimates that this proposed AD affects 206 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
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85............................. $0 $85 $17,510
----------------------------------------------------------------------------------------------------------------
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 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
[[Page 39780]]
under the criteria of the Regulatory Flexibility Act.
