Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2B16 (604 Variant) airplanes. This 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 AD requires revising the existing airplane flight manual (AFM) to add new limitations and procedures. The FAA is issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain Bombardier,
Inc., Model CL-600-2B16 (604 Variant) airplanes. The NPRM published in
the Federal Register on February 2, 2023 (88 FR 7013). The NPRM was
prompted by AD CF-2022-45, dated August 11, 2022, issued by Transport
Canada, which is the aviation authority for Canada (referred to after
this as the MCAI). 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 Limitations 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.
In the NPRM, the FAA proposed to require revising the existing
airplane flight manual (AFM) to add new limitations and procedures. The
FAA is issuing this AD to address the unsafe condition on these
products.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-0010.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from an individual who supported the
NPRM without change.
Conclusion
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
referenced above. The FAA reviewed the relevant data, considered the
comment received, and determined that air safety requires adopting this
AD as proposed. Accordingly, the FAA is issuing this AD to address the
unsafe condition on this product. Except for minor editorial changes,
this AD is adopted as proposed in the NPRM. None of the changes will
increase the economic burden on any operator.

Costs of Compliance
The FAA estimates that this AD affects 409 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this 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
This AD will not have federalism implications under Executive Order
13132. This AD will 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 that this AD:
(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.

2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
2023-07-04 Bombardier, Inc.: Amendment 39-22406; Docket No. FAA-
2023-0010; Project Identifier MCAI-2022-01090-T.
(a) Effective Date
This airworthiness directive (AD) is effective May 30, 2023.
(b) Affected ADs
None.
(c) Applicability

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
