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 a combination of system faults and procedural actions will cause the ground spoilers to deploy in the air. This proposed AD would require revising the existing airplane flight manual (AFM) to add revised 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-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 <a href="http://regulations.gov">regulations.gov</a> 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
[[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.
