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 debonded 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 PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 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: E:\FR\FM\15SER1.SGM 15SER1 63514 Federal Register / Vol. 88, No. 178 / Friday, September 15, 2023 / Rules and Regulations ESTIMATED COSTS Action Labor cost Replace auxiliary motor and pump .................

SUPPLEMENTARY INFORMATION: Authority for This Rulemaking The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. 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. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of the airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it modifies Class E airspace to support IFR operations at Burley Municipal Airport, Burley, ID. History The FAA published a notice of proposed rulemaking for Docket No. FAA–2023–0763 in the Federal Register (88 FR 29569; May 8, 2023), proposing to modify Class E airspace at Burley Municipal Airport, Burley, ID. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 63515 proposal to the FAA. No comments were received. Differences From the NPRM Subsequent to the publication of the NPRM, the FAA discovered that the proposed legal description for Burley’s Class E airspace designated as a surface area required editing to better align with the intended airspace design, as well as to better match the Airspace Class definition. The legal description titled ‘‘ANM ID E2 Burley, ID [Amended]’’ (88 FR 29571; May 8, 2023) has been revised in this final rule to read: ‘‘That airspace extending upward from the surface within a 5-mile radius of Burley Municipal Airport, and that airspace extending upward from the surface between a 5-mile radius to a 7-mile radius southwest of the airport, from the 208° bearing clockwise to the 274° bearing from the airport.’’ Additionally, the FAA discovered that the proposed legal description for Burley’s Class E airspace extending upward from 700 feet or more above the surface required editing to better align with adjacent airspace and to correct geographical coordinates. The legal description titled ‘‘ANM ID E5 Burley, ID [Amended]’’ (88 FR 29571; May 8, 2023) has been revised in this final rule to read: ‘‘That airspace extending upward from 700 feet above the surface within a 5.6-mile radius of the airport, and within a 6.5-mile radius of the airport between the 274° bearing clockwise to the 074° bearing, and within a 7-mile radius of the airport, from the 208° bearing clockwise to the 274° bearing; That airspace extending upward from 1,200 feet above the surface beginning at lat. 42°36′45′′ N, long. 114°14′48′′ W; to lat. 43°0′1′′ N, long. 114°2′9′′ W; to lat. 42°59′59′′ N, long. 112°59′57′′ W; to lat. 42°29′59′′ N, long. 113°0′0′′ W; to lat. 42°4′13′′ N, long. 114°30′42′′ W; lat. 42°36′20′′ N, long. 114°14′35′′ W; lat. 42°36′27′′ N, long. 114°14′55′′ W, thence to the point of beginning.’’ None of these edits make substantive changes to the airspace volumes the FAA proposed. Incorporation by Reference Class E2 and E5 airspaces areas are published in paragraphs 6002 and 6005, respectively, of FAA Order JO 7400.11, Airspace Designations and Reporting Points, which is incorporated by reference in 14 CFR 71.1 on an annual basis. This document amends the current version of that order, FAA Order JO 7400.11H, dated August 11, 2023, and effective September 15, 2023.

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

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:

feather propellers. The unsafe condition, if not addressed, could 
result in reduced controllability of the aircraft and consequent 
loss of control of the aircraft.
