AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2020–03– 

24, which applied to certain Dassault 

Aviation Model MYSTERE–FALCON 

20–C5, 20–D5, 20–E5, and 20–F5 

airplanes. AD 2020–03–24 required 

revising the existing maintenance or 

inspection program, as applicable, to 

incorporate new or more restrictive 

airworthiness limitations. This AD was 

prompted by a determination that new 

or more restrictive airworthiness 

limitations are necessary. This AD 

continues to require the actions in AD

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2020–03–24, 

Amendment 39–19848 (85 FR 11289, 

February 27, 2020) (AD 2020–03–24). 

AD 2020–03–24 applied to certain 

Dassault Aviation Model MYSTERE– 

FALCON 20–C5, 20–D5, 20–E5, and 20– 

F5 airplanes. AD 2020–03–24 required 

revising the existing maintenance or 

inspection program, as applicable, to 

incorporate new or more restrictive 

airworthiness limitations. The FAA 

issued AD 2020–03–24 to address 

fatigue cracking, damage, and corrosion 

in principal structural elements, which 

could result in reduced structural 

integrity of the airplane. AD 2020–03– 

24 specifies that accomplishing the 

revision required by that AD terminates 

the requirements of paragraph (g)(1) of 

AD 2010–26–05, Amendment 39–16544 

(75 FR 79952, December 21, 2010), for 

Model MYSTERE–FALCON 20–C5, 20– 

D5, 20–E5, and 20–F5 airplanes on 

which the SSIP [Supplemental 

Structural Inspection Program (Dassault 

Service Bulletin 730)] has been 

embodied into the airplane’s existing 

maintenance or inspection program 

only. This AD therefore continues to 

allow that terminating action. 

The NPRM published in the Federal 

Register on July 19, 2023 (88 FR 46115). 

The NPRM was prompted by AD 2023– 

0062, dated March 20, 2023, issued by 

EASA, (EASA AD 2023–0062) (also 

referred to as the MCAI), which is the 

Technical Agent for the Member States 

of the European Union. The MCAI states 

that new or more restrictive 

airworthiness limitations have been 

developed. 

In the NPRM, the FAA proposed to 

continue to require the actions in AD 

2020–03–24 and proposed to require 

revising the existing maintenance or 

inspection program, as applicable, to 

incorporate new or more restrictive 

airworthiness limitations, as specified 

in EASA AD 2023–0062. The FAA is 

issuing this AD to address fatigue 

cracking, damage, and corrosion in 

principal structural elements, which 

could result in reduced structural 

integrity of the airplane. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2023–1495. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the cost to the public. 

Conclusion 

This product has been approved by 

the aviation authority of another 

country and is approved for operation in 

the United States. Pursuant to the FAA’s 

bilateral agreement with this State of 

Design Authority, it has notified the 

FAA of the unsafe condition described 

in the MCAI referenced above. 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 this 

product. Except for minor editorial 

changes, this AD is adopted as proposed 

in the NPRM. None of the changes will 

increase the economic burden on any 

operator. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2023–0062 specifies new or 

more restrictive airworthiness 

limitations for airplane structures and 

safe life limits. 

This AD also requires Chapter 5–40– 

01, Airworthiness Limitations, of the 

Dassault Falcon 20 Retrofit 731 

Maintenance Manual, Revision 10, 

dated January 1, 2019, which the 

Director of the Federal Register 

approved for incorporation by reference 

as of April 2, 2020 (85 FR 11289, 

February 27, 2020). 

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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 57 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

The FAA estimates the total cost per 

operator for the retained actions from 

AD 2020–03–24 to be $7,650 (90 workhours × $85 per work-hour). 

The FAA has determined that revising 

the existing maintenance or inspection 

program takes an average of 90 workhours per operator, although the agency 

recognizes that this number may vary 

from operator to operator. Since 

operators incorporate maintenance or 

inspection program changes for their 

affected fleet(s), the FAA has 

determined that a per-operator estimate 

is more accurate than a per-airplane 

estimate. 

The FAA estimates the total cost per 

operator for the new actions to be 

$7,650 (90 work-hours × $85 per workhour). 

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.

ACTION: Interim final rule. 

SUMMARY: This document contains 

interim final regulations relating to the 

imposition of certain user fees on tax 

return preparers. These regulations 

reduce the amount of the user fee to 

apply for or renew a preparer tax 

identification number (PTIN) and affect 

individuals who apply for or renew a 

PTIN. The Independent Offices 

Appropriation Act of 1952 authorizes 

the charging of user fees. The text of the 

interim final regulations also serves as 

the text of the proposed regulations set 

forth in the notice of proposed 

rulemaking on this subject in this issue 

in the Proposed Rules section of this 

edition of the Federal Register. 

DATES: 

Effective date: These regulations are 

effective on October 19, 2023. 

Applicability date: For date of 

applicability, see paragraph (d) of these

SUPPLEMENTARY INFORMATION: 

Background 

This document contains interim final 

amendments to 26 CFR part 300 

regarding user fees. 

A. User Fee Authority 

The Independent Offices 

Appropriation Act of 1952 (IOAA), 

which is codified at 31 U.S.C. 9701, 

authorizes agencies to prescribe 

regulations that establish user fees for 

services provided by the agency. The 

IOAA provides that regulations 

implementing user fees are subject to 

policies prescribed by the President; 

these policies are set forth in the Office 

of Management and Budget Circular A– 

25, 58 FR 38142 (July 15, 1993) (OMB 

Circular A–25). 

Under OMB Circular A–25, Federal 

agencies that provide services that 

confer benefits on identifiable recipients 

are to establish user fees that recover the 

full cost of providing the service. An 

agency that seeks to impose a user fee 

for government-provided services must 

calculate the full cost of providing those 

services. In general, a user fee should be 

set at an amount that allows the agency 

to recover the direct and indirect costs 

of providing the service, unless the 

Office of Management and Budget 

(OMB) grants an exception. OMB 

Circular A–25 provides that agencies are 

to review user fees biennially and 

update them as necessary. 

B. PTIN Requirement 

Section 6109(a)(4) of the Internal 

Revenue Code (Code) authorizes the 

Secretary of the Treasury or her delegate 

to prescribe regulations for the inclusion 

of a tax return preparer’s identifying 

number on a return, statement, or other 

document required to be filed with the 

IRS. On September 30, 2010, the
