contains steps that are labeled as Required
for Compliance (RC), the provisions of
paragraphs (j)(4)(i) and (j)(4)(ii) of this AD
apply.
(i) The steps labeled as RC, including
substeps under an RC step and any figures
identified in an RC step, must be done to
comply with the AD. If a step or substep is
labeled ‘‘RC Exempt,’’ then the RC
requirement is removed from that step or
substep. An AMOC is required for any
deviations to RC steps, including substeps
and identified figures.
(ii) Steps not labeled as RC may be
deviated from using accepted methods in
accordance with the operator’s maintenance
or inspection program without obtaining
approval of an AMOC, provided the RC steps,
including substeps and identified figures, can
still be done as specified, and the airplane
can be put back in an airworthy condition.

Discussion
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian
Airworthiness Directive CF–2017–01,
dated January 6, 2017 (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–604 Variant) airplanes.
The MCAI states:
A number of in-service incidents have been
reported on CL–600–2C10 aeroplanes
regarding a loss of all air data information
provided to the crew. The air data
information was recovered as the aeroplane
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 happen on Bombardier
Inc. CL–600–2B16 aeroplanes.
This [Canadian] AD mandates the
incorporation of Aircraft Flight Manual
(AFM) procedures to guide the crew to
stabilize the aeroplanes airspeed and attitude
for continued safe flight and landing.
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–2017–
0528.
Related Service Information Under 1
CFR Part 51
Bombardier, Inc., has issued
Unreliable Airspeed, of Section 03–15,
Instruments System, of Chapter 3,
Emergency Procedures, to the following
AFMs:
• Bombardier Challenger 604 AFM,
PSP 604–1, Revision 103, dated
November 28, 2016.
• Bombardier Challenger 605 AFM,
PSP 605–1, Revision 41, dated
November 28, 2016.
• Bombardier Challenger 650 AFM,
PSP 650–1, Revision 6, dated November
28, 2016.
This service information provides
revisions to the Emergency Procedures
section of the AFM to incorporate a
procedure for ‘‘Unreliable Airspeed.’’
These documents are distinct since they
apply to different airplane
configurations. This service information
is reasonably available because the
interested parties have access to it

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 the same
type design.
Costs of Compliance
We estimate that this proposed AD
affects 128 airplanes of U.S. registry.
We also estimate that it would take
about 1 work-hour per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $85 per work-hour. Based on
these figures, we estimate the cost of
this proposed AD on U.S. operators to
be $10,880, or $85 per product.
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 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.

Federal Register / Vol. 82, No. 106 / Monday, June 5, 2017 / Proposed Rules
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.

Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2017-01, dated January 6, 2017 (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-
604 Variant) airplanes. The MCAI states:
A number of in-service incidents have been reported on CL-600-
2C10 aeroplanes regarding a loss of all air data information
provided to the crew. The air data information was recovered as the
aeroplane 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 happen on Bombardier Inc. CL-600-2B16 aeroplanes.
This [Canadian] AD mandates the incorporation of Aircraft Flight
Manual (AFM) procedures to guide the crew to stabilize the
aeroplanes airspeed and attitude for continued safe flight and
landing.

0528.
Related Service Information Under 1 CFR Part 51
Bombardier, Inc., has issued Unreliable Airspeed, of Section 03-15,
Instruments System, of Chapter 3, Emergency Procedures, to the
following AFMs:
Bombardier Challenger 604 AFM, PSP 604-1, Revision 103,
dated November 28, 2016.
Bombardier Challenger 605 AFM, PSP 605-1, Revision 41,
dated November 28, 2016.
Bombardier Challenger 650 AFM, PSP 650-1, Revision 6,
dated November 28, 2016.
This service information provides revisions to the Emergency
Procedures section of the AFM to incorporate a procedure for
``Unreliable Airspeed.'' These documents are distinct since they apply
to different airplane 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 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 the same
type design.
Costs of Compliance
We estimate that this proposed AD affects 128 airplanes of U.S.
registry.
We also estimate that it would take about 1 work-hour per product
to comply with the basic requirements of this proposed AD. The average
labor rate is $85 per work-hour. Based on these figures, we estimate
the cost of this proposed AD on U.S. operators to be $10,880, or $85
per product.
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 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.
[[Page 25748]]
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.
