[Docket No. FAA-2022-1661; Project Identifier MCAI-2022-00714-T;
Amendment 39-22380; AD 2023-05-11]
RIN 2120-AA64
Airworthiness Directives; Bombardier, Inc., Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes.
This AD was prompted by a report that in case of a flap, slat, or slat-
flap failure in flight, resetting the slat flap control unit (SFCU) to
clear the error using the airplane flight manual (AFM) could result in
the stall protection computer (SPC) setting the low-speed cue to the
most conservative stall advance mode. This AD requires revising the
non-normal procedures section of the existing AFM to provide the
flightcrew with procedures for addressing failure warnings in the slat
and flap control systems. The FAA is issuing this AD to address the
unsafe condition on these products.
DATES: This AD is effective May 12, 2023.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of May 12, 2023.
ADDRESSES:
AD Docket: You may examine the AD docket at regulations.gov under
Docket No. FAA-2022-1661; or in person at Docket Operations between 9
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD
docket contains this final rule, the mandatory continuing airworthiness
information (MCAI), any comments received, and other information. The

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 BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published
in the Federal Register on January 13, 2023 (88 FR 2286). The NPRM was
prompted by AD CF-2022-30, dated June 3, 2022, (referred to after this
as the MCAI) issued by Transport Canada, which is the aviation
authority for Canada. The MCAI states in case of a flap, slat, or slat-
flap failure in flight, resetting the SFCU to clear the error using the
AFM could result in the SPC setting the low-speed cue to the most
conservative stall advance mode instead of that published in the AFM.
This condition could result in unexpected stall warnings (aural and
visual) as well as stick shaker activation during approach for a
landing, increasing flightcrew workload during a critical phase of
flight. The higher landing speed could consequently require a greater
landing distance and possible diversion to a longer runway.
In the NPRM, the FAA proposed to require revising the non-normal
procedures section of the existing AFM to provide the flightcrew with
procedures for addressing failure warnings in the slat and flap control
systems. The FAA is issuing this AD to address the unsafe condition on
these products.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2022-1661.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the cost to the public.
[[Page 20755]]
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 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 450 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 $38,250

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:
[[Page 20756]]
(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 Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 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:
2023-05-11 Bombardier, Inc.: Amendment 39-22380; Docket No. FAA-
2022-1661; Project Identifier MCAI-2022-00714-T.
(a) Effective Date
This airworthiness directive (AD) is effective May 12, 2023.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Bombardier, Inc., Model BD-700-1A10 and BD-
700-1A11 airplanes, certificated in any category, having serial
numbers 9001 through 9998 inclusive and 60001 through 60097
inclusive.
(d) Subject
Air Transport Association (ATA) of America Code 27, Flight
controls.
(e) Unsafe Condition
This AD was prompted by a report that in case of a flap, slat,
or slat-flap failure in flight, resetting the slat flap control unit
(SFCU) to clear the error using the airplane flight manual (AFM)
could result in the stall protection computer (SPC) setting the low-
speed cue to the most conservative stall advance mode. The FAA is
issuing this AD to address a flap, slat, or slat-flap failure
warning. The unsafe condition, if not addressed, could result in
unexpected stall warnings (aural and visual) as well as stick shaker
activation during approach for a landing, increasing flightcrew
workload during a critical phase of flight. The higher landing speed
could consequently require a greater landing distance and possible
diversion to a longer runway.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Revision of the Existing AFM
Within 30 days after the effective date of this AD: Revise the
existing AFM to incorporate the information specified in the AFM
sections of the applicable AFM revisions specified in figure 1 to
paragraph (g) of this AD.
