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 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.

-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes.

has an improved response time. 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 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 <a href="http://regulations.gov">regulations.gov</a> 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.
<bullet> Service Bulletin 700-32-044, Revision 01, dated December
7, 2022.
<bullet> Service Bulletin 700-32-6021, Revision 01, dated December
7, 2022.
<bullet> Service Bulletin 700-32-6507, Revision 01, dated December
7, 2022.
<bullet> Service Bulletin 700-1A11-32-031, Revision 01, dated
December 7, 2022.
<bullet> Service Bulletin 700-32-5021, Revision 01, dated December
7, 2022.
<bullet> 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.
