SUPPLEMENTARY INFORMATION: Comments Invited The FAA invites you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under ADDRESSES. Include ‘‘Docket No. FAA–2023–1398; Project Identifier AD– 2023–00472–P’’ at the beginning of your comments. The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. The FAA will consider all comments received by the closing date and may amend this proposal because of those comments. The FAA has been informed that Hamilton Sundstrand has done some outreach with affected operators regarding the proposed corrective actions for this unsafe condition. As a result, affected operators are already aware of the proposed corrective actions and, in some cases, have already begun planning for replacement of certain auxiliary motors and pumps. Therefore, the FAA has determined that a 30-day comment period is appropriate given the particular circumstances related to the proposed correction of this unsafe condition. Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, without change, to regulations.gov, including any personal information you provide. The agency will also post a report summarizing each substantive verbal contact received about this NPRM. Confidential Business Information CBI is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to this NPRM contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this NPRM, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission containing CBI as ‘‘PROPIN.’’ The FAA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this NPRM. Submissions containing CBI should be sent to Isabel Saltzman, Aviation Safety Engineer, FAA, 1701 Columbia Avenue, College Park, GA 30337. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA received 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. This condition, if not addressed, could result in reduced controllability of the aircraft and consequent loss of control of the aircraft. FAA’s Determination The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Related Service Information Under 1 CFR Part 51 The FAA reviewed Hamilton Sundstrand 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 ADDRESSES. Proposed AD Requirements in This NPRM This proposed AD would 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). This proposed AD would also prohibit installation of an auxiliary motor and pump having P/N 782655–3 (Aerocontrolex P/N 4122–006009) on any propeller. Differences Between This Proposed AD and the Service Information Where the service information specifies returning certain parts to Hamilton Sundstrand, this proposed AD does not contain that requirement. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 20 propellers installed on airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ddrumheller on DSK120RN23PROD with PROPOSALS1 ESTIMATED COSTS Action Replace auxiliary motor and pump. Perform post-installation system test. VerDate Sep<11>2014 17:46 Jun 26, 2023 Labor cost Cost per product Parts cost Cost on U.S. operators 2 work-hours × $85 per hour = $170 ..................................... $11,000 $11,170 $223,400 1 work-hour x $85 per hour = $85 ......................................... 0 85 1,700 Jkt 259001 PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 E:\FR\FM\27JNP1.SGM 27JNP1 Federal Register / Vol. 88, No. 122 / Tuesday, June 27, 2023 / Proposed Rules § 39.13 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 The FAA determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Would not affect intrastate aviation in Alaska, and (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. ddrumheller on DSK120RN23PROD with PROPOSALS1 The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

SUPPLEMENTARY INFORMATION: 

Comments Invited

    The FAA invites you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under ADDRESSES. Include ``Docket No. FAA-2023-1398; Project Identifier 
AD-2023-00472-P'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the proposal, explain the 
reason for any recommended change, and include supporting data. The FAA 
will consider all comments received by the closing date and may amend 
this proposal because of those comments.
    The FAA has been informed that Hamilton Sundstrand has done some 
outreach with affected operators regarding the proposed corrective 
actions for this unsafe condition. As a result, affected operators are 
already aware of the proposed corrective actions and, in some cases, 
have already begun planning for replacement of certain auxiliary motors 
and pumps. Therefore, the FAA has determined that a 30-day comment 
period is appropriate given the particular circumstances related to the 
proposed correction of this unsafe condition.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
regulations.gov, including any personal information you provide. The 
agency will also post a report summarizing each substantive verbal 
contact received about this NPRM.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this NPRM contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this NPRM, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this NPRM. Submissions containing CBI should be sent to 
Isabel Saltzman, Aviation Safety Engineer, FAA, 1701 Columbia Avenue, 
College Park, GA 30337. Any commentary that the FAA receives which is 
not specifically designated as CBI will be placed in the public docket 
for this rulemaking.

Background

    The FAA received 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. This 
condition, if not addressed, could result in reduced controllability of 
the aircraft and consequent loss of control of the aircraft.

FAA's Determination

    The FAA is issuing this NPRM after determining that the unsafe 
condition described previously is likely to exist or develop on other 
products of the same type design.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Hamilton Sundstrand 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 
ADDRESSES.

Proposed AD Requirements in This NPRM

    This proposed AD would 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). This 
proposed AD would also prohibit installation of an auxiliary motor and 
pump having P/N 782655-3 (Aerocontrolex P/N 4122-006009) on any 
propeller.

Differences Between This Proposed AD and the Service Information

    Where the service information specifies returning certain parts to 
Hamilton Sundstrand, this proposed AD does not contain that 
requirement.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 20 propellers installed on airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------

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

    The FAA determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.
