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 

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.

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.

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 

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.
