Background
Transport Canada, which is the
aviation authority for Canada, has
issued Transport Canada AD CF–2023–
01, dated January 4, 2023 (Transport
Canada AD CF–2023–01) (also referred
to as the MCAI), to correct an unsafe
condition on certain Bombardier, Inc.,
Model CL–600–2B16 (604 Variant)
airplanes. The MCAI states that, during
an in-service event, a combination of
system faults and procedural actions
caused the ground spoilers to deploy in
the air. During this event, the WOW
(weight on wheels) INPUT Caution
message had posted on the engine
indication and crew alerting system
(EICSA) after takeoff. The WOW INPUT
message persisted, even after the
flightcrew executed the WOW INPUT
Quick Reference Handbook (QRH)
procedure. During this time, the GND
SPLRS (ground spoilers) NOT ARMED
message also posted, and the flightcrew
consequently manually armed the
ground spoilers as required by
procedure. An investigation by
Bombardier, Inc., revealed that a fault
occurred in the proximity sensor
electronic unit (PSEU), which
erroneously indicated ON GROUND
while the airplane was in the air.
The FAA is proposing this AD to
address possible ground spoiler

deployment leading to reduced
controllability of the airplane, or
excessive loss of altitude on final
approach. You may examine the MCAI
in the AD docket at regulations.gov
under Docket No. FAA–2023–1219.

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 referenced 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
revising the existing AFM to add revised
procedures.
Transport Canada AD CF–2023–01
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
E:\FR\FM\05JYP1.SGM
05JYP1
42888
Federal Register / Vol. 88, No. 127 / Wednesday, July 5, 2023 / Proposed Rules
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 proposed, would affect 44
airplanes of U.S. registry. The FAA
estimates the following costs to comply
with this proposed AD:
ESTIMATED COSTS FOR REQUIRED ACTIONS

Authority for This Rulemaking
The Proposed Amendment
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.
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:
ddrumheller on DSK120RN23PROD with PROPOSALS1
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.

Background
Transport Canada, which is the aviation authority for Canada, has
issued Transport Canada AD CF-2023-01, dated January 4, 2023 (Transport
Canada AD CF-2023-01) (also referred to as the MCAI), to correct an
unsafe condition on certain Bombardier, Inc., Model CL-600-2B16 (604
Variant) airplanes. The MCAI states that, during an in-service event, a
combination of system faults and procedural actions caused the ground
spoilers to deploy in the air. During this event, the WOW (weight on
wheels) INPUT Caution message had posted on the engine indication and
crew alerting system (EICSA) after takeoff. The WOW INPUT message
persisted, even after the flightcrew executed the WOW INPUT Quick
Reference Handbook (QRH) procedure. During this time, the GND SPLRS
(ground spoilers) NOT ARMED message also posted, and the flightcrew
consequently manually armed the ground spoilers as required by
procedure. An investigation by Bombardier, Inc., revealed that a fault
occurred in the proximity sensor electronic unit (PSEU), which
erroneously indicated ON GROUND while the airplane was in the air.
The FAA is proposing this AD to address possible ground spoiler
deployment leading to reduced controllability of the airplane, or
excessive loss of altitude on final approach. You may examine the MCAI
in the AD docket at regulations.gov under Docket No. FAA-2023-1219.
Related Service Information Under 1 CFR Part 51
The FAA reviewed the following service information, which specifies
revised Abnormal Procedures of the AFM for Ground Spoilers Unsafe and
Weight-on-Wheels Input Fault procedures. These documents are distinct
since they apply to different airplane models and configurations.

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 referenced 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 revising the existing AFM to add
revised procedures.
Transport Canada AD CF-2023-01 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
[[Page 42888]]
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 proposed, would
affect 44 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 $3,740
----------------------------------------------------------------------------------------------------------------
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.
