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 all Hamilton Sundstrand
Model 14SF-17 and 14SF-19 propellers. The NPRM published in the Federal
Register on June 27, 2023 (88 FR 41513). The NPRM was prompted by a
report of an auxiliary motor and pump installed on a non-Hamilton
Sundstrand propeller failing to feather the propeller in flight through
either the primary or the backup means. The failure was caused by motor
magnets in the auxiliary motor and pump that were de-bonded due to
corrosion at the magnet and housing interface. The de-bonded motor
magnets prevented motor rotation. Hamilton Sundstrand Model 14SF-17 and
14SF-19 propellers use the same auxiliary motor and pump. These
propellers are installed on, but not limited to, Viking Air Limited
(type certificate previously held by Bombardier Inc.; Canadair Limited)
Model CL-215-6B11 (CL-215T & CL-415 Variants) airplanes. In the NPRM,
the FAA proposed to require the removal from service of an auxiliary
motor and pump having part number (P/N) 782655-3 (Aerocontrolex P/N
4122-006009) and replacement with an auxiliary motor and pump having P/
N 782655-4 (Aerocontrolex P/N 4122-056000). In the NPRM, the FAA also
proposed to prohibit installation of an auxiliary motor and pump having
P/N 782655-3 (Aerocontrolex P/N 4122-006009) on any propeller. The FAA
is issuing this AD to address the unsafe condition on these products.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the costs.
Conclusion
The FAA reviewed the relevant data and determined that air safety
requires adopting this AD as proposed. Accordingly, the FAA is issuing
this AD to address the unsafe condition on these products. Except for
minor editorial changes, this AD is adopted as proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Hamilton Sundstrand Corporation Service Bulletin
(SB) 14SF-61-168, Revision 1, dated December 21, 2016. This service
information specifies instructions for replacing the auxiliary motor
and pump. Hamilton Sundstrand Corporation is a UTC Aerospace Systems
Company. This service information is identified as both Hamilton
Sundstrand Corporation and UTC Aerospace Systems. 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 20 propellers installed on
airplanes of U.S. registry.
The FAA estimates the following costs to comply with this AD:

Perform post-installation system test. 1 work-hour x $85 per 0 85 1,700
hour = $85.
----------------------------------------------------------------------------------------------------------------
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.
