Background
DEPARTMENT OF TRANSPORTATION
Federal Aviation Administration
14 CFR Part 39
Federal Aviation
Administration (FAA), DOT.
ACTION: Final rule.
AGENCY:
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 the nose
wheel steering selector valve (SSV) can
be slow to deactivate under low
temperature conditions. This AD
requires replacing the affected SSV with
a re-designed SSV that has an improved
response time. The FAA is issuing this
AD to address the unsafe condition on
these products.
DATES: This AD is effective February 6,
2024.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in this AD
as of February 6, 2024.
ADDRESSES:
AD Docket: You may examine the AD
docket at regulations.gov under Docket
No. FAA–2023–1706; or in person at
Docket Operations between 9 a.m. and
5 p.m., Monday through Friday, except
Federal holidays. The AD docket
contains this final rule, the mandatory
continuing airworthiness information
(MCAI), any comments received, and
other information. The address for

SUMMARY:
PO 00000
Frm 00010
Fmt 4700
Sfmt 4700
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 August 9, 2023 (88
FR 53823). The NPRM was prompted by
AD CF–2023–02, dated January 11,
2023, issued by Transport Canada,
which is the aviation authority for
Canada (referred to after this as the
MCAI). The MCAI states that following
a runway excursion on a different
model, an investigation revealed that
the nose wheel SSV can be slow to
deactivate under low temperature
conditions. A similar SSV is installed
on the airplanes to which this AD is
applicable. In the event of an uncommanded steering input, a slow SSV
deactivation could lead to a delayed
transition to free caster mode and result
in an aircraft runway excursion.
In the NPRM, the FAA proposed to
require replacing the affected SSV with
a re-designed SSV that has an improved
response time. The FAA is issuing 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–2023–1706.
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.
Request To Add Bombardier Part
Numbers
NetJets suggested adding Bombardier
part numbers GW415–6275–1 &
GW415–6275–3 to paragraph (g) of the
proposed AD, in addition to Safran part
numbers, as stated in SB 700–32–6021,
paragraph 3., MATERIAL
INFORMATION. NetJets stated that, at
new aircraft delivery, the Bombardier
part numbers are provided in the
documentation of the aircraft. The FAA
infers that NetJets would like to ensure
the proper identification of the parts.

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.
The FAA concurs with the suggestion.
To aid in identifying the parts,
paragraph (g) of this AD has been
changed to add the referenced
Bombardier part numbers.
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
Related Service Information Under 1
CFR Part 51
The FAA reviewed the following
Bombardier service information.
• Service Bulletin 700–32–044,
Revision 01, dated December 7, 2022.
• Service Bulletin 700–32–6021,
Revision 01, dated December 7, 2022.
• Service Bulletin 700–32–6507,
Revision 01, dated December 7, 2022.
• Service Bulletin 700–1A11–32–031,
Revision 01, dated December 7, 2022.

• Service Bulletin 700–32–5021,
Revision 01, dated December 7, 2022.
• Service Bulletin 700–32–5507,
Revision 01, dated December 7, 2022.
This service information specifies
procedures for replacing the affected
SSV with a re-designed SSV. These
documents are distinct since they apply
to different airplane 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.
Costs of Compliance
The FAA estimates that this AD
affects 442 airplanes of U.S. registry.
The FAA estimates the following costs
to comply with this AD:
ESTIMATED COSTS FOR REQUIRED ACTIONS
Labor cost
Parts cost
4 work-hours × $85 per hour = $340 ................................
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
khammond on DSKJM1Z7X2PROD with RULES
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.

Airworthiness Directives; Bombardier, Inc., Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
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 the nose wheel steering selector
valve (SSV) can be slow to deactivate under low temperature conditions.
This AD requires replacing the affected SSV with a re-designed SSV that
has an improved response time. The FAA is issuing this AD to address
the unsafe condition on these products.
DATES: This AD is effective February 6, 2024.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of February 6,
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 BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published
in the Federal Register on August 9, 2023 (88 FR 53823). The NPRM was
prompted by AD CF-2023-02, dated January 11, 2023, issued by Transport
Canada, which is the aviation authority for Canada (referred to after
this as the MCAI). The MCAI states that following a runway excursion on
a different model, an investigation revealed that the nose wheel SSV
can be slow to deactivate under low temperature conditions. A similar
SSV is installed on the airplanes to which this AD is applicable. In
the event of an un-commanded steering input, a slow SSV deactivation
could lead to a delayed transition to free caster mode and result in an
aircraft runway excursion.
In the NPRM, the FAA proposed to require replacing the affected SSV
with a re-designed SSV that has an improved response time. The FAA is
issuing 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-2023-1706.
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.
Request To Add Bombardier Part Numbers
NetJets suggested adding Bombardier part numbers GW415-6275-1 &
GW415-6275-3 to paragraph (g) of the proposed AD, in addition to Safran
part numbers, as stated in SB 700-32-6021, paragraph 3., MATERIAL
INFORMATION. NetJets stated that, at new aircraft delivery, the
Bombardier part numbers are provided in the documentation of the
aircraft. The FAA infers that NetJets would like to ensure the proper
identification of the parts.
[[Page 15]]
The FAA concurs with the suggestion. To aid in identifying the
parts, paragraph (g) of this AD has been changed to add the referenced
Bombardier part numbers.
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.
Related Service Information Under 1 CFR Part 51
The FAA reviewed the following Bombardier service information.
Service Bulletin 700-32-044, Revision 01, dated December
7, 2022.
Service Bulletin 700-32-6021, Revision 01, dated December
7, 2022.
Service Bulletin 700-32-6507, Revision 01, dated December
7, 2022.
Service Bulletin 700-1A11-32-031, Revision 01, dated
December 7, 2022.
Service Bulletin 700-32-5021, Revision 01, dated December
7, 2022.
Service Bulletin 700-32-5507, Revision 01, dated December
7, 2022.
This service information specifies procedures for replacing the
affected SSV with a re-designed SSV. These documents are distinct since
they apply to different airplane 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.
Costs of Compliance
The FAA estimates that this AD affects 442 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per
Labor cost Parts cost product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
4 work-hours x $85 per hour = $340............ $5,542 $5,882 Up to $2,599,844.
----------------------------------------------------------------------------------------------------------------
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.
