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 a combination of system faults and procedural actions will cause the ground spoilers to deploy in the air. This AD requires revising the existing airplane flight manual (AFM) to add revised procedures. The FAA is issuing this AD to address the unsafe condition on these products.

manual (AFM) to add revised procedures. The FAA is issuing this AD to
address the unsafe condition on these products.
DATES: This AD is effective March 20, 2024.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of March 20,
2024.

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 July 5, 2023 (88 FR 42886). The NPRM was
prompted by AD CF-2023-01, dated January 4, 2023, issued by Transport
Canada (hereafter referred to as the MCAI), which is the aviation
authority for Canada. 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.
In the NPRM, the FAA proposed to require revision of the existing
AFM to add revised procedures. The FAA is issuing 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.
Discussion of Final Airworthiness Directive
Comments
The FAA received one comment from a commenter who supported the
NPRM without change.
The FAA received additional comments from Bombardier. The following
presents the comments received and the FAA's responses.
[[Page 11165]]
Request for Later-Approved Service Information
Bombardier requested that the FAA change the AD to allow the use of
the AFM revisions specified ``or later revisions approved by the FAA,
TCCA [Transport Canada Civil Aviation], or the Bombardier DAO [Design
Approval Organization].''
The FAA disagrees with the commenter's request. The FAA may not
refer to any future document that does not yet exist in an AD because 1
CFR 51.1(f) states a publication's incorporation by reference is
limited to its approved edition; future publication amendments or
revisions are outside this inclusion.
Further, paragraph (g) of this AD requires operators to incorporate
``the information specified in'' the specified AFM documents. If
operators incorporate a later revision of an AFM document that contains
the same information as the specified AFM document, then they are in
compliance with paragraph (g) of this AD. However, if there are changes
to procedures in later revisions, operators may request an alternative
method of compliance with this AD under the provisions of paragraph
(h)(1) of this AD.
Additional Changes Made to This Final Rule
In the NPRM, the FAA inadvertently referred to Sub-sub-section K,
``Ground Spoilers Unsafe,'' of Bombardier Challenger 604 Airplane
Flight Manual, Publication No. PSP 604-1, Revision 125, dated March 14,
2022. The ``Ground Spoilers Unsafe,'' procedure of that document is
actually ``Sub-sub-section L.'' Therefore, the FAA has revised all
references of ``Sub-sub-section K'' to ``Sub-sub-section L.''
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
comments 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, and any other changes described previously, this AD is adopted
as proposed in the NPRM. None of the changes will increase the economic
burden on any operator.

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.
