Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed 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 proposed AD would 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 proposing this AD to address the unsafe condition on these products.

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-700-1A10 and BD-700-1A11
airplanes. This proposed 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
proposed AD would 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 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-2022-30, dated June 3, 2022 (Transport
Canada AD CF-2022-30) (also referred to after this as the MCAI), to
correct an unsafe condition on certain Bombardier, Inc., Model BD-700-
1A10 and BD-700-1A11 airplanes. 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.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2022-1661.

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 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-2022-30 requires operators to ``advise all
flight crews'' of revisions to the AFM, and thereafter to ``operate the
aeroplane 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
[[Page 2288]]
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 proposed, would
affect 450 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 $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
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.

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-2022-1661; Project Identifier MCAI-
2022-00714-T.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by February 27, 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.
