Federal Register / Vol. 87, No. 64 / Monday, April 4, 2022 / Proposed Rules 19405 

with the Farm Credit Administration 

financial reports, certified by FCSIC, as 

required by § 621.14. 

(5) Each institution in conservatorship 

must prepare and issue published 

financial reports in accordance with the 

requirements of part 620 of this chapter. 

FCSIC, as the conservator of the 

institution, will provide the signatures 

and certifications required by § 620.3. 

(c) Termination of the 

conservatorship. (1) Whenever the Farm 

Credit Administration Board determines 

that the problem(s) or condition(s) that 

led to the conservatorship have been 

corrected and resolved, and the 

institution is in a position to resume 

normal operations, it may terminate the 

conservatorship and direct FCSIC to 

turn over the institution’s operations to 

such management that FCA designates. 

Once new management is in place, the 

conservatorship terminates and FCA 

discharges FCSIC as conservator; or 

(2) Whenever the Farm Credit 

Administration Board determines that 

the institution should be placed in 

receivership, the Farm Credit 

Administration Board will appoint 

FCSIC as the receiver of such 

institution. 

Subpart C—Receiver and 

Receiverships 

§ 627.20 FCSIC as receiver. 

(a) Appointment. (1) The Farm Credit 

Administration Board may exercise its 

authority under section 4.12(b) of the 

Act and § 627.3 to appoint FCSIC as the 

receiver of a Farm Credit institution 

upon finding that one or more of the 

grounds identified in § 627.3(b) exists. 

The Farm Credit Administration Board 

may appoint, ex parte and without 

notice, FCSIC as receiver for any Farm 

Credit institution. 

(2) Upon appointing FCSIC as the 

receiver of an institution, the Chairman 

of the Farm Credit Administration shall 

immediately notify such institution and, 

in the case of an association, its funding 

bank. The Farm Credit Administration 

will immediately publish notice of the 

appointment of the receiver in the 

Federal Register. 

(b) Funding bank role for association 

in liquidation. In the event of the 

voluntary or involuntary liquidation of 

an association, the funding bank must 

institute appropriate measures to 

minimize the adverse effect of the 

liquidation on those borrowers whose 

loans are purchased by, or otherwise 

transferred to another System 

institution. 

(c) Receivership. (1) Once the Farm 

Credit Administration Board issues the 

order placing a Farm Credit institution 

in receivership, all rights, privileges, 

and powers of its members, the board of 

directors, officers, and employees, are 

transferred to and vested exclusively in 

FCSIC as receiver, except that the 

institution’s board of directors retains 

authority to initiate an action in a 

Federal district court to remove the 

receiver pursuant to § 627.4. 

(2) The Farm Credit Administration 

Board simultaneously will cancel the 

charter of the institution when it 

appoints FCSIC as receiver. 

(d) Uninsured accounts. Once the 

Farm Credit Administration Board has 

placed an institution into receivership, 

FCSIC, in accordance with section 4.37 

of the Act, will, as soon as practicable, 

notify every borrower who holds an 

uninsured voluntary or involuntary 

account, as described in § 614.4175 of 

this chapter, at the institution that: 

(1) Such accounts ceased earning 

interest from the date that the Farm 

Credit Administration Board placed the 

institution into receivership; and 

(2) FCSIC, as receiver, will 

immediately apply the funds in a 

borrower’s uninsured account(s) as 

payment against the outstanding 

balance of the borrower’s loan(s). 

(e) Final discharge and release of the 

receiver. The receivership terminates 

after FCSIC makes a final distribution of 

the assets of the liquidated institution. 

Then, the Farm Credit Administration 

Board will completely and finally 

release and discharge the receiver.

(a) * * * In the event the resolution 

to liquidate is approved by the 

stockholders of the Farm Credit 

institution and the liquidation plan is 

approved by the Farm Credit 

Administration Board, the liquidation 

plan shall govern disposition of the 

equities of the Farm Credit institution.

Airworthiness Directives; Pratt & 

Whitney Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2021–14–06, which applies to all Pratt 

& Whitney (PW) PW1519G, PW1521G, 

PW1521G–3, PW1521GA, PW1524G, 

PW1524G–3, PW1525G, PW1525G–3, 

PW1919G, PW1921G, PW1922G, 

PW1923G, and PW1923G–A model 

turbofan engines. AD 2021–14–06 

requires repetitive borescope 

inspections (BSI) of certain low-pressure 

compressor (LPC) rotor 1 (R1) until 

replacement of electronic engine control 

(EEC) full authority digital electronic 

control (FADEC) software with updated 

software. AD 2021–14–06 also requires 

a BSI after installation of the updated 

EEC FADEC software if certain Onboard 

Maintenance Message fault codes are 

displayed and meet specified criteria. 

AD 2021–14–06 also requires, 

depending on the results of the BSI, 

replacement of the LPC R1. Since the 

FAA issued AD 2021–14–06, the 

manufacturer redesigned the 

compressor intermediate case (CIC) 

assembly to incorporate a shortened 

bleed duct configuration and updated 

the EEC FADEC software. This proposed 

AD would continue to require repetitive 

BSI of certain LPC R1s until 

replacement of EEC FADEC software 

with updated software and also a BSI 

after installation of the updated EEC 

FADEC software if certain Onboard 

Maintenance Message fault codes are 

displayed and meet specified criteria. 

This proposed AD would continue to 

require, depending on the results of the 

BSI, replacement of the LPC R1. This 

proposed AD would also require 

removal and replacement of the existing 

CIC assembly with a CIC assembly 

eligible for installation. The FAA is

public docket for this rulemaking. 

Background 

The FAA issued AD 2021–14–06, 

Amendment 39–21633 (86 FR 36061, 

July 8, 2021), (AD 2021–14–06), for all 

PW PW1519G, PW1521G, PW1521G–3, 

PW1521GA, PW1524G, PW1524G–3, 

PW1525G, PW1525G–3, PW1919G, 

PW1921G, PW1922G, PW1923G, and 

PW1923G–A model turbofan engines. 

AD 2021–14–06 was prompted by 

reports of in-flight shutdowns due to 

failure of the LPC R1 and by subsequent 

findings of cracked LPC R1s during 

inspection. Additionally, the 

manufacturer performed further root 

cause analysis of the LPC R1 failures 

and determined the need to update the 

EEC FADEC software to automate rotor 

speed management and limit the 

maximum climb and maximum 

continuous thrust ratings. AD 2021–14– 

06 requires repetitive BSIs of certain 

LPC R1s until replacement of EEC 

FADEC software with the updated 

software, and a BSI after installation of 

the updated EEC FADEC software if 

certain Onboard Maintenance Message 

fault codes are displayed and meet 

specified criteria. AD 2021–14–06 also 

requires, depending on the results of the 

BSI, replacement of the LPC R1. The 

agency issued AD 2021–14–06 to 

prevent failure of the LPC R1. 

Actions Since AD 2021–14–06 Was 

Issued 

Since the FAA issued AD 2021–14– 

06, the manufacturer performed further 

analysis and determined the need for 

corrective action. The manufacturer 

redesigned the CIC assembly to 

incorporate a shortened bleed duct 

configuration. The shortened bleed duct 

will address the unsafe condition by 

preventing the coincidence between 

bleed and the acoustic excitation. The 

manufacturer also updated the EEC 

FADEC software to provide 

compatibility with both current and 

future operation of engines and 

airplanes with the redesigned CIC 

assembly installed. 

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.

017, dated March 19, 2021, describes 

procedures for performing a BSI of the 

LPC. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would retain 

certain requirements of AD 2021–14–06. 

This proposed AD would continue to 

require removal from service of certain 

EEC FADEC software and the 

installation of a software version eligible 

for installation. This proposed AD 

would require a BSI of LPC R1 for 

damage and cracks after replacing 

certain EEC FADEC software versions 

and would continue to require a BSI of 

LPC R1 after installation of an eligible 

EEC FADEC software version if certain 

Onboard Maintenance Message fault 

codes are displayed and meet specified 

criteria. This proposed AD would 

continue to require, depending on the 

results of the BSI, replacement of the 

LPC R1. This proposed AD would also 

require removal and replacement of 

certain CIC assemblies, identified by 

part number, with a CIC assembly 

eligible for installation. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 114 

engines installed on airplanes of U.S. 

registry. The FAA estimates that five 

percent of engines installed on airplanes 

of U.S. registry would require BSI of the 

LPC R1, as proposed in paragraph (g)(3) 

of this AD, after installation of the EEC 

FADEC software version eligible for 

installation. 

The FAA estimates the following 

costs to comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Replace EEC FADEC software ...................... 2 work-hours × $85 per hour = $170 ............. $0 $170 $19,380 

BSI of the LPC R1 .......................................... 2 work-hours × $85 per hour = $170 ............. 0 170 969 

Replace CIC assembly ................................... 428 work-hours × $85 per hour = $36,380 .... 124,522 160,902 18,342,828 

The FAA estimates the following 

costs to do any necessary inspection if 

certain Onboard Maintenance Message 

fault codes are displayed or if any 

necessary replacement would be 

required based on the results of the 

proposed inspection. The agency has no 

way of determining the number of 

aircraft that might need these 

replacements or inspections: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replace LPC R1 ........................................................... 40 work-hours × $85 per hour = $3,400 ...................... $156,000 $159,400 

BSI of the LPC R1 if Onboard Maintenance Message 

fault codes are displayed and meet specified criteria.

2 work-hours × $85 per hour = $170 ........................... 0 170 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some of the 

costs of this proposed AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

individuals. 

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.

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 would 

modify the route structure as necessary 

to preserve the safe and efficient flow of 

air traffic within the National Airspace 

System (NAS).

Reference 

This document proposes to amend 

FAA Order JO 7400.11F, Airspace 

Designations and Reporting Points, 

dated August 10, 2021, and effective

Background 

The aviation industry/users have 

indicated a desire for the FAA to 

transition the Alaskan en route 

navigation structure away from the 

dependency on NDBs. The advances in 

technology have allowed for alternate 

navigation methods to support 

decommissioning of high cost ground 

navigation equipment. The FAA 

conducted a non-rulemaking study in 

accordance with FAA Order JO 7400.2, 

Procedures for Handling Airspace 

Matters in 2021 on SQM due to the 

ongoing high cost of maintenance and
