SUPPLEMENTARY INFORMATION: 

I. Discussion

The NRC is issuing a revision in the

NRC’s ‘‘Regulatory Guide’’ series. This 

series was developed to describe 

methods that are acceptable to the NRC 

staff for implementing specific parts of 

the agency’s regulations, to explain 

techniques that the staff uses in 

evaluating specific issues or postulated 

events, and to describe information that 

the staff needs in its review of 

applications for permits and licenses. 

The proposed Revision 2 to RG 1.73 

was issued with a temporary 

identification of Draft Regulatory Guide, 

(DG)–1386 (ADAMS Accession No. 

ML23055B024). This revision endorses, 

with exceptions, additions, and 

clarifications, the methods described in 

the Institute of Electrical and 

Electronics Engineers (IEEE) Standard 

(Std.) 382–2019, ‘‘IEEE Standard for 

Qualification of Safety-Related 

Actuators for Nuclear Power Generating 

Stations and Other Nuclear Facilities.’’ 

II. Additional Information

The NRC published notice of the

availability of DG–1386 in the Federal 

Register on May 22, 2023 (88 FR 32693), 

for a 30-day public comment period. 

The public comment period closed on 

June 21, 2023. Public comments on DG– 

1386 and the staff responses to the 

public comments are available under 

ADAMS under Accession No. 

ML23198A312. 

As noted in the Federal Register on 

December 9, 2022 (87 FR 75671), this 

document is being published in the 

‘‘Rules’’ section of the Federal Register 

to comply with publication 

requirements under 1 CFR chapter I. 

III. Congressional Review Act

This RG is a rule as defined in the

Congressional Review Act (5 U.S.C. 

801–808). However, the Office of 

Management and Budget has not found 

it to be a major rule as defined in the 

Congressional Review Act. 

IV. Backfitting, Forward Fitting, and

Issue Finality

Issuance of RG 1.73 Revision 2, would 

not constitute backfitting as defined in 

§ 50.109 of title 10 of the Code of

Federal Regulations (10 CFR),

‘‘Backfitting,’’ and as described in NRC

Management Directive (MD) 8.4,

‘‘Management of Backfitting, Forward

Fitting, Issue Finality, and Information

Requests’’; affect issue finality of any

approval issued under 10 CFR part 52,

‘‘Licenses, Certificates, and Approvals

for Nuclear Power Plants’’; or constitute

forward fitting as defined in MD 8.4,

because, as explained in this RG,

licensees would not be required to

comply with the positions set forth in

this RG.

V. Submitting Suggestions for

Improvement of Regulatory Guides

A member of the public may, at any 

time, submit suggestions to the NRC for 

improvement of existing RGs or for the 

development of new RGs. Suggestions 

can be submitted on the NRC’s public 

website at https://www.nrc.gov/readingrm/doc-collections/reg-guides/ 

contactus.html. Suggestions will be 

considered in future updates and 

enhancements to the ‘‘Regulatory 

Guide’’ series.

ACTION: Final rule. 

Editorial Note: Rule document R1–2023– 

28853 published on pages 3342–3344 in the 

issue of Thursday, January 18, 2024. In that 

publication, on page 3343, in the second 

column, in the paragraph ‘‘(a) Effective 

Date,’’ on the second line, ‘‘February 16, 

2024’’ should read ‘‘February 7, 2024’’. The 

rule is republished here corrected and in its 

entirety. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2023–04– 

10, which applied to all Dassault 

Aviation Model MYSTERE–FALCON 

900 airplanes. AD 2023–04–10 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 

2023–04–10, and requires revising the 

existing maintenance or inspection 

program, as applicable, to incorporate 

new or more restrictive airworthiness 

limitations; as specified in a European 

Union Aviation Safety Agency (EASA) 

AD, which is incorporated by reference. 

The FAA is issuing this AD to address 

the unsafe condition on these products. 

DATES: This AD is effective February 7, 

2024. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of February 7, 2024. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain other publication listed in 

this AD as of May 12, 2023 (88 FR

docket at regulations.gov under Docket 

No. FAA–2023–1502; or in person at

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2023–04–10, 

Amendment 39–22357 (88 FR 20743, 

April 7, 2023) (AD 2023–04–10). AD 

2023–04–10 applied to all Dassault 

Aviation Model MYSTERE–FALCON 

900 airplanes. AD 2023–04–10 required 

revising the existing maintenance or 

inspection program, as applicable, to 

incorporate new or more restrictive 

airworthiness limitations. The FAA 

issued AD 2023–04–10 to address 

reduced structural integrity of the 

airplane. AD 2023–04–10 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) (AD 2010–26–05) 

for Dassault Aviation Model MYSTERE– 

FALCON 900 airplanes only. This AD 

therefore continues to allow that 

terminating action. 

The NPRM published in the Federal 

Register on July 21, 2023 (88 FR 47086); 

corrected August 14, 2023 (88 FR 

54933). The NPRM was prompted by 

AD 2023–0046, dated March 2, 2023, 

issued by EASA, which is the Technical 

Agent for the Member States of the 

European Union (EASA AD 2023–0046) 

(also referred to as the MCAI). 

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 

2023–04–10 and to require revising the 

existing maintenance or inspection 

program, as specified in EASA AD 

2023–0046. The FAA is issuing this AD 

to address reduced structural integrity 

of the airplane. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2023–1502. 

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 

The FAA reviewed EASA AD 2023– 

0046. This service information specifies 

new or more restrictive airworthiness 

limitations for airplane structures and 

safe life limits. 

This AD also requires EASA AD 

2022–0137, dated July 6, 2022, which 

the Director of the Federal Register 

approved for incorporation by reference 

as of May 12, 2023 (88 FR 20743, April 

7, 2023). 

This material is reasonably available 

because the interested parties have 

access to it through their normal course
