Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for
certain Bombardier, Inc., Model CL–
600–2B16 (601–3A, 601–3R, and 604
Variants) airplanes. This proposed AD
was prompted by reports from the
supplier that sensing elements of the
bleed air leak detection system were
manufactured with insufficient salt fill,
which can result in an inability to detect
hot bleed air leaks. This proposed AD
would require testing of all affected
overheat detection sensing elements of
the bleed air leak detection system, and
replacement if necessary. This proposed
AD would also prohibit the installation
of affected parts. 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–
05, dated February 8, 2023 (Transport
Canada AD CF–2023–05) (also referred
to after this as the MCAI), to correct an
unsafe condition on certain Bombardier,
Inc., Model CL–600–2B16 (601–3A,
601–3R, and 604 Variants) airplanes.
The MCAI states that Bombardier
received reports from the supplier of the
overheat detection sensing elements of a
manufacturing quality escape. Some of
the sensing elements of the bleed air
leak detection system were
PO 00000
Frm 00040
Fmt 4702
Sfmt 4702

manufactured with insufficient salt fill,
which can result in an inability to detect
hot bleed air leaks and cause damage to
surrounding structures and systems that
can prevent continued safe flight and
landing.
The FAA is proposing 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–2023–1710.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Bombardier
Service Bulletin 604–36–005,
Bombardier Service Bulletin 605–36–
002, and Bombardier Service Bulletin
650–36–001, all dated December 23,
2022. This service information specifies
procedures for testing affected bleed air
leak detection system sensing elements
(i.e., those marked with a date code
before ‘‘A2105’’ (which corresponds to
January 31, 2021) with a part number
defined in this service information) to
determine if they are serviceable, and
replacing failed sensing elements with
serviceable ones. These documents are
distinct since they apply to different
airplane serial numbers.
The FAA reviewed Kidde Aerospace
& Defense Service Bulletin CFD–26–1,
Revision 6, dated February 28, 2022.
This service information specifies
affected continuous fire detector part
numbers and testing procedures.
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
accomplishing the actions specified in
the service information already
described. This proposed AD would
also prohibit the installation of affected
parts.

for each airplane.
The FAA has included all known
costs in its cost estimate. According to
the manufacturer, however, some or all
of the costs of this proposed AD may be
covered under warranty, thereby
reducing the cost impact on affected
operators.
Authority for This Rulemaking
ddrumheller on DSK120RN23PROD with PROPOSALS1
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
VerDate Sep<11>2014
16:45 Aug 11, 2023
Jkt 259001
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.

AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for
certain Airbus Canada Limited
Partnership Model BD–500–1A10 and
BD–500–1A11 airplanes. This proposed
AD was prompted by reports of
mechanical wear damage on the motive
flow fuel-feed tubes that were secured
by bonding clamps and clamp blocks
inside the collector tank. This proposed
AD would require repetitive operational
checks of the gravity cross flow shut-off
valve and, for certain airplanes, a onetime inspection of the motive flow fuelfeed tubes at the clamp blocks location,
and corrective action if necessary, as
specified in a Transport Canada AD,
which is proposed for incorporation by
reference (IBR). The FAA is proposing
this AD to address the unsafe condition
on these products.
DATES: The FAA must receive comments
on this proposed AD by September 28,
2023.

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain Bombardier, Inc., Model CL-600-2B16 (601-3A, 601-3R, and
604 Variants) airplanes. This proposed AD was prompted by reports from
the supplier that sensing elements of the bleed air leak detection
system were manufactured with insufficient salt fill, which can result
in an inability to detect hot bleed air leaks. This proposed AD would
require testing of all affected overheat detection sensing elements of
the bleed air leak detection system, and replacement if necessary. This
proposed AD would also prohibit the installation of affected parts. 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-2023-05, dated February 8, 2023
(Transport Canada AD CF-2023-05) (also referred to after this as the
MCAI), to correct an unsafe condition on certain Bombardier, Inc.,
Model CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. The
MCAI states that Bombardier received reports from the supplier of the
overheat detection sensing elements of a manufacturing quality escape.
Some of the sensing elements of the bleed air leak detection system
were manufactured with insufficient salt fill, which can result in an
inability to detect hot bleed air leaks and cause damage to surrounding
structures and systems that can prevent continued safe flight and
landing.
The FAA is proposing 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-2023-1710.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Bombardier Service Bulletin 604-36-005, Bombardier
Service Bulletin 605-36-002, and Bombardier Service Bulletin 650-36-
001, all dated December 23, 2022. This service information specifies
procedures for testing affected bleed air leak detection system sensing
elements (i.e., those marked with a date code before ``A2105'' (which
corresponds to January 31, 2021) with a part number defined in this
service information) to determine if they are serviceable, and
replacing failed sensing elements with serviceable ones. These
documents are distinct since they apply to different airplane serial
numbers.
The FAA reviewed Kidde Aerospace & Defense Service Bulletin CFD-26-
1, Revision 6, dated February 28, 2022. This service information
specifies affected continuous fire detector part numbers and testing
procedures.
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 accomplishing the actions specified
in the service information already described. This proposed AD would
also prohibit the installation of affected parts.
[[Page 54948]]
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 694 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 37 work-hours x $85 per hour = Up $0 Up to $3,145.............. Up to $2,182,630.
to $3,145.
----------------------------------------------------------------------------------------------------------------
The estimates the following costs to do any necessary on-condition
actions that would be required based on the results of any required
actions. The FAA has no way of determining the number of aircraft that
might need these on-condition actions.
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
37 work-hours x $85 per hour = $3,145. * $4,000 $7,145
------------------------------------------------------------------------
* The FAA has received no definitive data on which to base the cost
estimates for the parts specified in this proposed AD. This is the
estimated cost for replacement of 2 percent of the failed sensing
elements. If all sensing elements failed, the estimated parts cost
would be $40,000 for each airplane.
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some or all of the costs of
this proposed AD may be covered under warranty, thereby reducing the
cost impact on affected operators.
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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
