14 CFR Part 39
[Docket No. FAA-2019-1081; Product Identifier 2019-NM-153-AD]
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 BD-100-1A10 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 existing
airplane flight manual (AFM) to provide the flightcrew with procedures
to 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 March
12,
2020.
ADDRESSES: You may send comments, using the procedures found in
14 CFR
11.43 and 11.45, by any of the following methods:
Federal eRulemaking Portal: Go to https://www.regulations.gov. Follow
the
instructions for submitting comments.
Fax: 202-493-2251.

Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2019-24, dated July 5,
2019 (referred to after this as the Mandatory Continuing Airworthiness
Information, or "the MCAI"), to correct an unsafe condition for
certain Bombardier, Inc., Model BD-100-1A10 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-2019-1081.
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. The FAA is proposing this AD to address the
loss of all air data system information provided to the flightcrew. If
not addressed, this condition may adversely affect continued safe
flight and landing. See the MCAI for additional background information.
Related Service Information Under 1 CFR Part 51
Bombardier has issued the following service information, which
provides a procedure for "Unreliable Airspeed" in the Emergency
Procedures section, and also provides a procedure for "Go-Around" in
the Normal Procedures section of the applicable AFM. These documents
are distinct since they apply to different airplane models.
Bombardier Challenger 300 AFM, Publication No. CSP 100-1,
Revision 56, dated July 8, 2019.
Bombardier Challenger 350 AFM, Publication No. CH 350 AFM,
Revision 22, dated July 8, 2019.
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 the FAA's 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 FAA 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 and with procedures for "Go-Around" in
the Normal Procedures section of the applicable AFM, as described
previously.
Costs of Compliance
The FAA estimates that this proposed AD affects 560 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
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 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
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.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
