ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to supersede Airworthiness Directive (AD) 2018–03–13, which applies to certain General Electric Company (GE) CT7– 5A2, CT7–5A3, CT7–7A, CT7–7A1, CT7–9B, CT7–9B1, CT7–9B2, CT7–9C, and CT7–9C3 model turboprop engines. AD 2018–03–13 requires initial and repetitive visual inspections and fluorescent penetrant inspections (FPIs) of the main propeller shaft. Since the FAA issued AD 2018–03–13, the manufacturer detected two additional cracks on a main propeller shaft during its ongoing investigation and subsequently published service information that introduced reduced inspection thresholds for initial and repetitive visual inspections, FPIs, and added initial and repetitive ultrasonic inspections (USIs) of the main propeller shaft. Additionally, the manufacturer revised the airworthiness limitations section (ALS) of the maintenance manual (MM) to incorporate initial and repetitive USIs to inspect for cracks on the main propeller shaft. This proposed AD would require initial and repetitive visual inspections, FPIs, and USIs of the main propeller shaft. Depending on the results of these inspections, this proposed AD would require replacement of the main propeller shaft. As an optional terminating action to these inspections, this proposed AD would require revising the ALS of the existing MM and the operator’s existing approved maintenance program or inspection program, as applicable, to incorporate the tasks and reduced inspection thresholds for the main propeller shaft. The FAA is proposing this AD to address the unsafe condition on these products. DATES: The FAA must receive comments on this proposed AD by December 16, 2022. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: SUMMARY: PO 00000 Frm 00012 Fmt 4702 Sfmt 4702 • Federal eRulemaking Portal: Go to regulations.gov.

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 issued AD 2018–03–13, Amendment 39–19186 (83 FR 6125, February 13, 2018) (AD 2018–03–13), for certain GE CT7–5A2, CT7–5A3, CT7–7A, CT7–7A1, CT7–9B, CT7–9B1, CT7–9B2, CT7–9C, and CT7–9C3 model turboprop engines with main propeller shaft, part number 77581–11, installed. AD 2018–03–13 was prompted by an inflight failure of a main propeller shaft on a GE CT7–9B model turboprop engine, resulting in the loss of the propeller. The manufacturer determined the failure of the main propeller shaft was caused by cracks initiating from undiscovered corrosion in the dowel pin holes on the flange of the main propeller shaft. AD 2018–03–13 requires visually inspecting the main propeller shaft for wear, corrosion, and cracking and performing FPI for cracks. The agency issued AD 2018–03–13 to prevent failure of the main propeller shaft. The unsafe condition, if not addressed, could result in in-flight loss of the propeller, loss of engine thrust control, and damage to the airplane. Actions Since AD 2018–03–13 Was Issued Since the FAA issued AD 2018–03– 13, the manufacturer detected two additional cracks on a main propeller shaft during its ongoing investigation and subsequently published service information that introduced reduced inspection thresholds for initial and repetitive visual inspections, FPIs, and added initial and repetitive USIs of the main propeller shaft. Additionally, the manufacturer revised the ALS of the MM to incorporate initial and repetitive USIs to inspect for cracks on the main propeller shaft. 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 GE Service Bulletin (SB) CT7–TP 72–0541 R01, dated November 18, 2021 (GE SB CT7– TP 72–0541). This service information specifies procedures for performing initial and repetitive visual inspections, FPIs, and USIs of the main propeller shaft. This service information is reasonably available because the interested parties have access to it through their normal 65695 course of business or by the means identified in ADDRESSES. Proposed AD Requirements in This NPRM This proposed AD would retain none of the requirements of AD 2018–03–13. This proposed AD would require initial and repetitive visual inspections, FPIs, and USIs of the main propeller shaft. Depending on the results of these inspections, this proposed AD would require replacement of the main propeller shaft. As an optional terminating action to these inspections, this proposed AD would require revising the ALS of the existing MM and the operator’s existing approved maintenance program or inspection program, as applicable, to incorporate incorporating the tasks and reduced inspection thresholds for the main propeller shaft. An owner/operator (pilot) holding at least at least a private pilot certificate may revise the ALS of the existing MM, and the owner/ operator must enter compliance with the applicable paragraphs of the AD into the aircraft records in accordance with 14 CFR 43.9(a) and 14 CFR 91.417(a)(2)(v). The record must be maintained as required by 14 CFR 91.417, 14 CFR 121.380, or 14 CFR 135.439. This is an exception to the FAA’s standard maintenance regulations. Differences Between This Proposed AD and the Service Information GE SB CT7–TP 72–0541 uses the term ‘‘UTI,’’ while this proposed AD uses the term ‘‘USI.’’ Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 176 engines installed on airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: lotter on DSK11XQN23PROD with PROPOSALS1 ESTIMATED COSTS Action Labor cost Visually inspect, FPI, and USI the main propeller shaft. 2 work-hours × $85 per hour = $170 ............. The FAA estimates the following costs to do any necessary replacement that would be required based on the VerDate Sep<11>2014 16:25 Oct 31, 2022 Jkt 259001 results of the proposed inspections.

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. lotter on DSK11XQN23PROD with PROPOSALS1 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 that the proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, VerDate Sep<11>2014 16:25 Oct 31, 2022 Jkt 259001 (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. 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.

Any public comment received after the comment period’s closing date is considered late and will not be considered in the final rulemaking. FOR FURTHER INFORMATION CONTACT: Terry Rouch, Assistant Director, Loan Policy and Valuation, and Stephanie Li, Chief, Regulations, Loan Guaranty Service (26), Veterans Benefits Administration, Department of Veterans Affairs, 810 Vermont Avenue NW, Washington, DC 20420, (202) 632–8862 (This is not a toll-free telephone number.) SUPPLEMENTARY INFORMATION: The proposed rulemaking described by this notice would update VA’s existing IRRRL regulation at 38 CFR 36.4307 to reflect current statutory requirements set forth by section 309 of the Economic Growth, Regulatory Relief, and Consumer Protection Act, Public Law 115–174, 132 Stat. 1296, and section 2 of the Protecting Affordable Mortgages for Veterans Act of 2019, Public Law 116–33, 133 Stat. 1038 (collectively, the ‘‘Acts’’). The subject provisions of the Acts are codified at 38 U.S.C. 3709. Section 3709 sets forth statutory criteria for determining whether VA can guarantee or insure a refinance loan. PO 00000 Frm 00018 Fmt 4702 Sfmt 4702 Additional statutory authorities underpinning VA’s proposed rulemaking include 38 U.S.C. 3710, 3703, and 501. IRRRLs are specifically authorized under subsections (a)(8), (a)(11), and (e) of 38 U.S.C. 3710. I. Background (Note: VA does not use the term IRRRL in the proposed rule text. For ease of reading, however, this preamble substitutes the term ‘‘IRRRL’’ for the proposed rule text’s ‘‘refinancing loan’’. The terms are interchangeable in this context.) A. Section 3709 Background Discussion 1. IRRRLs Described The purpose of an IRRRL is to improve a veteran’s financial position by reducing the interest rate on the veteran’s existing VA-backed loan. An IRRRL typically results in a reduction in the dollar amount the veteran owes toward monthly housing loan payments. See 38 CFR 36.4307(a)(3). An IRRRL may be used alternatively to reduce the veteran’s required number of monthly loan payments, to convert an adjustablerate mortgage (ARM) to a loan with a fixed interest rate, or to make energy efficient improvements to the home. Id. A veteran cannot use an IRRRL to obtain cash for the equity the veteran may have in the property securing the loan, because that would be a cash-out refinance. See 38 CFR 36.4306. 2. Section 3709’s Effect on IRRRLs VA-backed refinancing loans were historically divided into two categories. See Revisions to VA-Guaranteed or Insured Cash-Out Home Refinance Loans, 83 FR 64459 (Dec. 17, 2018). The two categories were cash-outs offered under 38 U.S.C. 3710(a)(5) or 3710(a)(9) and IRRRLs. Id. As VA noted in its cash-out refinance interim final rule (IFR) notice, Congress structured 38 U.S.C. 3709 such that VAbacked refinance loans have since been effectively grouped into three categories: (i) IRRRLs, (ii) cash-outs in which the amount of the principal for the refinancing loan is equal to or less than the payoff amount on the loan being refinanced (Type I Cash-Outs), and (iii) cash-outs in which the amount of the principal for the refinancing loan is larger than the payoff amount of the loan being refinanced (Type II CashOuts). 83 FR at 64459. Subsections (a) through (c) of section 3709 apply to IRRRLs. Id. at 64460. Each of these three subsections creates a pass/fail standard applicable to IRRRLs. If one or more of the requirements is not met, VA cannot guarantee the IRRRL. See id. at 64462. E:\FR\FM\01NOP1.SGM 01NOP1

RIN 2120-AA64


Airworthiness Directives; General Electric Company Turboprop 
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2018-03-13, which applies to certain General Electric Company (GE) CT7-
5A2, CT7-5A3, CT7-7A, CT7-7A1, CT7-9B, CT7-9B1, CT7-9B2, CT7-9C, and 
CT7-9C3 model turboprop engines. AD 2018-03-13 requires initial and 
repetitive visual inspections and fluorescent penetrant inspections 
(FPIs) of the main propeller shaft. Since the FAA issued AD 2018-03-13, 
the manufacturer detected two additional cracks on a main propeller 
shaft during its ongoing investigation and subsequently published 
service information that introduced reduced inspection thresholds for 
initial and repetitive visual inspections, FPIs, and added initial and 
repetitive ultrasonic inspections (USIs) of the main propeller shaft. 
Additionally, the manufacturer revised the airworthiness limitations 
section (ALS) of the maintenance manual (MM) to incorporate initial and 
repetitive USIs to inspect for cracks on the main propeller shaft. This 
proposed AD would require initial and repetitive visual inspections, 
FPIs, and USIs of the main propeller shaft. Depending on the results of 
these inspections, this proposed AD would require replacement of the 
main propeller shaft. As an optional terminating action to these 
inspections, this proposed AD would require revising the ALS of the 
existing MM and the operator's existing approved maintenance program or 
inspection program, as applicable, to incorporate the tasks and reduced 
inspection thresholds for the main propeller shaft. The FAA is 
proposing this AD to address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by December 
16, 2022.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

11.35, the FAA will post all comments received, without change, to

[[Page 65695]]

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 
Sungmo Cho, Aviation Safety Engineer, ECO Branch, FAA, 1200 District 
Avenue, Burlington, MA 01803. 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 issued AD 2018-03-13, Amendment 39-19186 (83 FR 6125, 
February 13, 2018) (AD 2018-03-13), for certain GE CT7-5A2, CT7-5A3, 
CT7-7A, CT7-7A1, CT7-9B, CT7-9B1, CT7-9B2, CT7-9C, and CT7-9C3 model 
turboprop engines with main propeller shaft, part number 77581-11, 
installed. AD 2018-03-13 was prompted by an in-flight failure of a main 
propeller shaft on a GE CT7-9B model turboprop engine, resulting in the 
loss of the propeller. The manufacturer determined the failure of the 
main propeller shaft was caused by cracks initiating from undiscovered 
corrosion in the dowel pin holes on the flange of the main propeller 
shaft. AD 2018-03-13 requires visually inspecting the main propeller 
shaft for wear, corrosion, and cracking and performing FPI for cracks. 
The agency issued AD 2018-03-13 to prevent failure of the main 
propeller shaft. The unsafe condition, if not addressed, could result 
in in-flight loss of the propeller, loss of engine thrust control, and 
damage to the airplane.

Actions Since AD 2018-03-13 Was Issued

    Since the FAA issued AD 2018-03-13, the manufacturer detected two 
additional cracks on a main propeller shaft during its ongoing 
investigation and subsequently published service information that 
introduced reduced inspection thresholds for initial and repetitive 
visual inspections, FPIs, and added initial and repetitive USIs of the 
main propeller shaft. Additionally, the manufacturer revised the ALS of 
the MM to incorporate initial and repetitive USIs to inspect for cracks 
on the main propeller shaft.

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 GE Service Bulletin (SB) CT7-TP 72-0541 R01, dated 
November 18, 2021 (GE SB CT7-TP 72-0541). This service information 
specifies procedures for performing initial and repetitive visual 
inspections, FPIs, and USIs of the main propeller shaft.
    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 retain none of the requirements of AD 2018-
03-13. This proposed AD would require initial and repetitive visual 
inspections, FPIs, and USIs of the main propeller shaft. Depending on 
the results of these inspections, this proposed AD would require 
replacement of the main propeller shaft. As an optional terminating 
action to these inspections, this proposed AD would require revising 
the ALS of the existing MM and the operator's existing approved 
maintenance program or inspection program, as applicable, to 
incorporate incorporating the tasks and reduced inspection thresholds 
for the main propeller shaft. An owner/operator (pilot) holding at 
least at least a private pilot certificate may revise the ALS of the 
existing MM, and the owner/operator must enter compliance with the 
applicable paragraphs of the AD into the aircraft records in accordance 
with 14 CFR 43.9(a) and 14 CFR 91.417(a)(2)(v). The record must be 
maintained as required by 14 CFR 91.417, 14 CFR 121.380, or 14 CFR 
135.439. This is an exception to the FAA's standard maintenance 
regulations.

Differences Between This Proposed AD and the Service Information

    GE SB CT7-TP 72-0541 uses the term ``UTI,'' while this proposed AD 
uses the term ``USI.''

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 176 engines installed on airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

    The FAA estimates the following costs to do any necessary 
replacement that would be required based on the results of the proposed 
inspections. The agency has no way of determining the number of 
aircraft that might need this replacement:

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 that the 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.
