of his or her TSP balance invested in the 

TSP core funds, subject to the following 

rules: 

(1) The participant must establish a 

mutual fund window account that is 

separate from his or her TSP account. A 

participant with more than one TSP 

account may establish a separate mutual 

fund window account for each TSP 

account, and the limitations and fees 

described in subpart will apply 

separately to each account; 

(2) If the participant does not have an 

acknowledgment of risk on file as of the 

date of his or her initial fund transfer 

request to the mutual fund window, the 

participant must complete an 

acknowledgment of risk for the fund 

transfer to be processed; 

(3) Fund transfers must be made in 

whole dollar increments (percentages 

are not permitted); 

(4) The following limitations must be 

satisfied: 

(i) A participant’s initial fund transfer 

into his or her mutual fund window 

account must be at least $10,000 and 

may not exceed 25 percent of the 

participant’s TSP account balance, as of 

the date of such transfer; and 

(ii) Subsequent fund transfers into a 

participant’s mutual fund window 

account may not cause the balance in 

the participant’s mutual fund window 

account to exceed 25 percent of the 

participant’s total TSP balance, as of the 

date of any such transfer; 

(5) Each fund transfer into the mutual 

fund window counts toward the 

monthly limit set forth in § 1601.32(b); 

(6) Amounts transferred to a 

participant’s mutual fund window 

account will initially be invested in a 

sweep money market fund. 

Subsequently, the participant may 

direct the investment of the transferred 

amounts into any mutual fund(s) that 

are available through the mutual fund 

window; 

(7) Fund transfers are subject to the 

fees set forth in § 1601.53; and 

(8) A participant may not withdraw 

funds directly from his or her mutual 

fund window account. To make a 

withdrawal, the participant must elect a 

fund transfer back to the TSP core funds 

as described in paragraph (b) of this 

section. Upon completion of such fund 

transfer, the participant may make a 

withdrawal in accordance with 5 CFR 

part 1650. 

(b) Fund transfers back to TSP core 

funds. A participant may elect to make 

a fund transfer to the TSP core funds 

from amounts invested in his or her 

mutual fund window account, subject to 

the following rules: 

(1) Fund transfers must be made in 

whole dollar increments (percentages 

are not permitted); 

(2) Amounts to be transferred from a 

participant’s mutual fund window 

account to the TSP core funds must first 

be transferred to the sweep money 

market fund. Subsequently, the 

participant may direct the investment of 

the transferred amounts into the TSP 

core funds; 

(3) Each fund transfer back to the TSP 

core funds from the mutual fund 

window account counts toward the 

monthly limit set forth in § 1601.32(b); 

except, however, that a participant may 

always elect a fund transfer from the 

mutual fund window account to the G 

Fund; and 

(4) Fund transfers are subject to the 

fees set forth in § 1601.53. 

(c) Forced transfers. The TSP record 

keeper will force a transfer from the 

participant’s mutual fund window 

account to the TSP core funds in the 

following situations, and subject to the 

following rules: 

(1) A forced transfer may occur if the 

balance invested in the TSP core funds 

is insufficient to cover: 

(i) Amounts necessary to comply with 

a court order, legal process, or levy 

described in 5 CFR part 1653; 

(ii) A beneficiary asset transfer; 

(iii) A required minimum 

distribution; 

(iv) An automatic cash out 

distribution; or 

(v) Any other payment or transfer that 

the Board is required by law to make 

from the participant’s TSP account 

balance; 

(2) The amount of the forced transfer 

shall be equal to the amount of the 

insufficiency described in paragraph 

(c)(1) of this section, plus $1,000; 

except, however, that if the participant’s 

mutual fund window account balance is 

less than $25,000, the entire mutual 

fund window account balance shall be 

transferred to the TSP core funds; 

(3) Forced transfers shall be 

liquidated from the participant’s mutual 

fund window account first from 

amounts held in the sweep money 

market fund; and then from amounts 

invested in mutual funds, beginning 

with the position with the highest 

balance; 

(4) Forced transfers from a 

participant’s mutual fund window 

account to the TSP core funds shall be 

invested according to the participant’s 

existing contribution allocation; and 

(5) The participant shall be 

responsible for any fees incurred as a 

result of the forced transfer. 

§ 1601.53 Fees. 

(a) The Board will allocate a portion 

of the TSP’s administrative expenses to 

mutual fund users by charging an 

administrative fee of $55.00 annually. 

The amount of this fee will be 

redetermined once every three years by 

multiplying the average mutual fund 

window account balance by the TSP 

administrative expense ratio, as of the 

date of redetermination. 

(b) The fee described in paragraph (a) 

of this section is in addition to any 

mutual fund window account 

maintenance fees, trading fees, and fees 

and expenses associated with the 

specific mutual fund(s) in which the 

participant chooses to invest.

SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2020–0200, 

dated September 21, 2020 (EASA AD 

2020–0200), to correct an unsafe 

condition on Pilatus Model PC–24 

airplanes, all serial numbers. EASA AD 

2020–0200 was prompted by a report 

that, during climb, a Model PC–24 

airplane experienced a dual ethernet 

communication channel failure on a 

dual-channel data concentration and 

processing unit. The failure triggered 

the opening of electronic circuit 

breakers, which led to degradation of 

environmental control system 

functionalities, the deployment of all 

passenger oxygen masks, and the 

autopilot entering into emergency 

descent mode. According to EASA, 

various crew alerting system messages 

were displayed and the functionality of 

other systems (such as flaps, fuel 

indication, and the ice protection 

system) was significantly degraded. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all Pilatus Model PC–24 

airplanes. The NPRM published in the 

Federal Register on February 3, 2022 

(87 FR 6087). The NPRM was prompted 

by the failure of the dual ethernet 

communication channel on a dualchannel data concentration and 

processing unit identified in EASA AD 

2020–0200. The NPRM proposed to 

require installing a SW upgrade to the 

UMS, as specified in EASA AD 2020– 

0200. 

The FAA is issuing this AD to prevent 

failure of the dual ethernet 

communication channel on a dualchannel data concentration and 

processing unit. The unsafe condition, if 

not addressed, could result in increased 

pilot workload and reduced control of 

the airplane. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the costs. 

Conclusion 

These airplanes have been approved 

by EASA and are approved for operation 

in the United States. Pursuant to the 

FAA’s bilateral agreement with the 

European Union, EASA notified the 

FAA about the unsafe condition 

described in the EASA AD. 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. This AD is adopted as 

proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed EASA AD 2020– 

0200, which specifies upgrading the 

UMS SW and prohibits installing an 

earlier version of the SW. This material 

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. 

Other Related Service Information 

The FAA reviewed Pilatus PC–24 

Service Bulletin No. 42–010, dated 

January 21, 2020. This service 

information contains procedures for 

upgrading the UMS SW to Build 7.3. 

Differences Between This AD and the 

EASA AD 

Where EASA AD 2020–0200 requires 

compliance after its effective date, this 

AD requires using the effective date of 

this AD. Where EASA AD 2020–0200 

prohibits the installation of an affected 

part ‘‘from the effective date’’ of EASA 

AD 2020–0200, this AD requires using 

‘‘as of the effective date of this AD.’’ 

Although the service information 

referenced in EASA AD 2020–0200 

specifies reporting information to the 

manufacturer, this AD does not include 

that requirement. 

Costs of Compliance 

The FAA estimates that this AD 

affects 42 airplanes of U.S. registry. 

The FAA estimates the following 

costs to comply with this AD: 

ESTIMATED COSTS

Action Labor Cost Parts cost Cost per 

airplane 

Cost on U.S. 

operators 

Install SW upgrade to UMS ............................ 8 work-hours × $85 per hour = $680 ............. $5,000 $5,680 $238,560 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some of the 

costs of this AD may be covered under 

warranty, thereby reducing the cost 

impact on affected operators. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 


lotter on DSK11XQN23PROD with RULES1
Federal Register / Vol. 87, No. 90 / Tuesday, May 10, 2022 / Rules and Regulations 27925 

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 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.
