Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2B16 (604 Variant) airplanes. This proposed AD was prompted by a determination that during certain 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 add new limitation and procedures. The FAA is proposing this AD to address the unsafe condition on these products.

Background
Transport Canada, which is the aviation authority for Canada, has
issued Transport Canada AD CF-2022-45, dated August 11, 2022 (Transport
Canada AD CF-2022-45) (also referred to after this as the MCAI), to
correct an unsafe condition on certain Model CL-600-2B16 (604 Variant)
airplanes. The MCAI states that during (V) ALTS CAP or (V) ALTV CAP
modes, the flight guidance/autopilot does not account for engine
failure while capturing an altitude. If an engine failure occurs during
or before a climb while in one of these modes, the airspeed may
decrease rapidly below the safe operating speed, and prompt crew
intervention may be required to maintain a safe operating speed.
Transport Canada AD CF-2022-45 requires updating the Limitation and
Abnormal Procedures of the AFM for (V) ALTS CAP or (V) ALTV CAP modes
to address the unsafe condition for the affected Model CL-600-2B16 (604
Variant) airplanes. These updates include:
<bullet> A warning regarding the potential airspeed decay in the
case of an engine failure during a climb while in (V) ALTS CAP or (V)
ALTV CAP modes.
<bullet> A new procedure to adjust the pitch attitude to maintain
the required operating airspeed in the case of an engine failure during
a climb while in (V) ALTS CAP or (V) ALTV CAP modes.
The unsafe condition, if not addressed, could result in the
airplane failing to maintain a safe operating speed.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-0010.
Related Service Information Under 1 CFR Part 51
The FAA reviewed the following service information, which specifies
revised Limitations and Abnormal Procedures of the AFM for (V) ALTS CAP
or (V) ALTV CAP modes. These documents are distinct since they apply to
different airplane models and configurations.

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 this State of Design Authority,
it has notified the FAA of the unsafe condition described in the MCAI
and service information described above. The FAA is issuing this NPRM
after determining that the unsafe condition described previously is
likely to exist or develop on other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in the service information already described.
Transport Canada AD CF-2022-45 requires operators to ``advise all
flight crews'' of revisions to the AFM, and thereafter to ``operate the
affected aircraft accordingly.'' However, this proposed AD would not
specifically require those actions as those actions are already
required by FAA regulations. FAA regulations require operators furnish
to pilots any changes to the AFM (for example, 14 CFR 121.137), and to
ensure the pilots are familiar with the AFM (for example, 14 CFR
91.505). As with any other flightcrew training requirement, training on
the updated AFM content is tracked by the operators and recorded in
each pilot's training record, which is available for the FAA to review.
FAA regulations also require pilots to follow the procedures in the
existing AFM including all updates. 14 CFR 91.9 requires that any
person operating a civil aircraft must comply with the operating
limitations specified in the AFM. Therefore, including a requirement in
this proposed AD to operate the airplane according to the revised AFM
would be redundant and unnecessary.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposal, would
affect 409 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 $34,765
----------------------------------------------------------------------------------------------------------------
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.
[[Page 7015]]
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.

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
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
Bombardier, Inc.: Docket No. FAA-2023-0010; Project Identifier MCAI-
2022-01090-T.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by March 20, 2023.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Bombardier, Inc., Model CL-600-2B16 (604
Variant) airplanes, certificated in any category, serial numbers (S/

6050 through 6160 inclusive.
(d) Subject
Air Transport Association (ATA) of America Code 22, Auto flight.
(e) Unsafe Condition
This AD was prompted by a determination that during (V) ALTS CAP

account for engine failure while capturing an altitude. The FAA is
issuing this AD to address the possible occurrence of an engine
failure during or before a climb while in (V) ALTS CAP or (V) ALTV
CAP modes, which could cause the airspeed to decrease rapidly. The
unsafe condition, if not addressed, could result in the airplane
failing to maintain a safe operating speed.
