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-600-1A11 (600), CL-600-2A12 
(601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. 
This proposed AD was prompted by reports that during certain operating 
modes, the flight guidance/autopilot does not account for engine 
failure while capturing an altitude. This proposed AD would require 
revising the existing airplane flight manual (AFM) to provide the 
flightcrew with a new limitation and procedure for operation during 
certain flight modes. 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 May 26, 
2022.

Background

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued TCCA AD CF-2020-02, dated February 13, 
2020 (TCCA AD CF-2020-02) (also referred to as 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,

[[Page 21038]]

601-3R, and 604 Variants) 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-2022-0398.
    This proposed AD was prompted by reports that during ALTSEL, ASEL, 
or ALTS CAP mode, the flight guidance/autopilot does not account for 
engine failure while capturing an altitude. The FAA is proposing this 
AD to address a possible engine failure during or before a climb while 
in ALTSEL, ASEL or ALTS CAP mode, which could cause the airspeed to 
drop significantly below the safe operating speed. Prompt crew 
intervention may be required to maintain a safe operating speed. See 
the MCAI for additional background information.

Related Service Information Under 1 CFR Part 51

    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

    These products have been approved by the aviation authority of 
another country, and are 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 these same type 
designs.

Proposed Requirements of This NPRM

    This proposed AD would require revising the existing AFM to provide 
the flightcrew with a new limitation and procedure for operation during 
flight in certain flight modes.

Differences Between This Proposed AD and the MCAI

    This NPRM updates certain AFM revision levels identified in TCCA AD 
CF-2020-02, and therefore identifies the complete, most recent service 
information that will be incorporated by reference in the final rule. 
Operators should note that Bombardier revised the ALTS CAP mode to (V) 
ALTS CAP or

[[Page 21039]]

(V) ALTV CAP mode in a revision prior to the latest revisions of the 
Bombardier Challenger 604/605/650 AFMs referenced in this AD.

Costs of Compliance

    The FAA estimates that this proposed AD affects 133 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) Would not affect intrastate aviation in Alaska, and
    (3) Would 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

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.
