Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by reports that some overheat detection 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 AD requires maintenance records verification, and if an affected part is installed, would prohibit the use of certain Master Minimum Equipment List (MMEL) items under certain conditions by requiring revising the operator's existing Minimum Equipment List (MEL). This AD also requires testing the overheat detection sensing elements, marking each serviceable sensing element with a witness mark, and replacing each nonserviceable part with a serviceable part. This AD also prohibits the installation of affected parts under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes.
This AD was prompted by reports that some overheat detection 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 AD requires maintenance records verification, and
if an affected part is installed, would prohibit the use of certain
Master Minimum Equipment List (MMEL) items under certain conditions by
requiring revising the operator's existing Minimum Equipment List
(MEL). This AD also requires testing the overheat detection sensing
elements, marking each serviceable sensing element with a witness mark,
and replacing each nonserviceable part with a serviceable part. This AD
also prohibits the installation of affected parts under certain
conditions. The FAA is issuing this AD to address the unsafe condition
on these products.

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 BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published
in the Federal Register on November 15, 2023 (88 FR 78251). The NPRM
was prompted by AD CF-2023-17, dated March 8, 2023 (Transport Canada AD
CF-2023-17) (also referred to as the MCAI), issued by Transport Canada,
which is the aviation authority for Canada. 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. This condition can result in an inability to
detect hot bleed air leaks, which can cause damage to surrounding
structures and systems and prevent continued safe flight and landing.
In the NPRM, the FAA proposed to require maintenance records
verification, and if an affected part is installed, would prohibit the
use of certain MMEL items under certain conditions by requiring
revising the operator's existing MEL. The NPRM also proposed to require
testing the overheat detection sensing elements, marking each
serviceable sensing element with a witness mark, and replacing each
nonserviceable part with a serviceable part. The NPRM also proposed to
prohibit the installation of affected parts under certain conditions.
The FAA is issuing this AD to address the unsafe condition on these
products.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-2000.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from NetJets. The following presents the
comment received on the NPRM and the FAA's response to the comment.
Request for Clarification on Location of Date of Manufacture
NetJets requested a statement be added to paragraph (h) of the
proposed AD that the date of manufacture can be found in the aircraft
maintenance logbook, in addition to the identification plate of the
airplane on certain airplanes. This information is stated in Transport
Canada AD CF-2023-17, Part II, paragraph (A). NetJets further stated
that Bombardier no longer stamps a date on the airframe data plate.
The FAA agrees the date of manufacture can be found either on the
identification plate of certain airplanes or in the aircraft
maintenance logbook. The FAA has amended paragraph (h) of this AD to
specify the two locations where the date of manufacture can be found.
Change to NPRM Applicability
Paragraph (c) of this AD has been revised to clarify that the
applicability is limited to certain serial numbers, which are also
identified in Transport Canada AD CF-2023-17.
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
comment 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.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Liebherr Service Bulletin CFD-F1958-26-01, dated
May 6, 2022, which specifies part numbers for affected sensing
elements.
The FAA reviewed the following Bombardier service bulletins, which
specify procedures for testing each leak detection loop (LDL) sensing
element installed on the airplane, marking each serviceable sensing
element with a witness mark, and replacing each nonserviceable part
with a serviceable part. These documents are distinct since they apply
to different airplane models and configurations.

Costs of Compliance
The FAA estimates that this AD affects 160 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
[[Page 22071]]
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 140 work-hours x $85 per hour $0 Up to $11,900................ Up to $1,904,000.
= $11,900.
----------------------------------------------------------------------------------------------------------------
The FAA has received no definitive data on which to base the cost
estimates for the on-condition actions specified in this AD. The FAA
estimates it takes up to 1.5 hours to replace one sensor.
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some or all of the costs of
this 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
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.
