II. Additional Information 

The NRC is issuing for public 

comment a DG 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 

NRC’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 DG, entitled ‘‘Qualification of 

Fiber-Optic Cables, Connections, and 

Optical Fiber Splices for Use in Safety 

Systems for Production and Utilization 

Facilities,’’ is temporarily identified by 

its task number, DG–1427, and describes 

an approach that is acceptable to the 

NRC staff for use in complying with 

NRC regulations that address the 

environmental qualification of fiberoptic cables, connections, and optical 

fiber splices in safety systems in 

production and utilization facilities.

85890 Federal Register / Vol. 89, No. 209 / Tuesday, October 29, 2024 / Proposed Rules 

DG–1427 is newly proposed Revision 

0 of RG 1.257 and endorses, subject to 

the conditions described in Section C of 

this DG, the Institute of Electrical and 

Electronics Engineers Standard 1682– 

2023, which provides methods, 

directions, and documentation for the 

qualification of fiber optic cables, 

connections, and optical fiber splices in 

safety systems of production and 

utilization facilities. 

The staff is also issuing for public 

comment a draft regulatory analysis 

(ADAMS Accession No. ML24201A069). 

The staff developed a regulatory 

analysis to assess the value of issuing or 

revising an RG as well as alternative 

courses of action. 

As noted in the Federal Register on 

December 9, 2022 (87 FR 75671), this 

document is being published in the 

‘‘Proposed Rules’’ section of the Federal 

Register to comply with publication 

requirements under chapter I of title 1 

of the Code of Federal Regulations 

(CFR). 

III. Backfitting, Forward Fitting, and 

Issue Finality 

Issuance of DG–1427, if finalized, 

would not constitute backfitting as 

defined in 10 CFR 50.109, ‘‘Backfitting,’’ 

and as described in NRC Management 

Directive (MD) 8.4, ‘‘Management of 

Backfitting, Forward Fitting, Issue 

Finality, and Information Requests’’; 

does not affect issue finality of any 

approval issued under 10 CFR part 52, 

‘‘Licenses, Certificates, and Approvals 

for Nuclear Power Plants’’; nor 

constitute forward fitting as defined in 

MD 8.4, because, as explained in this 

DG, licensees would not be required to 

comply with the positions set forth in 

this DG. 

IV. 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.

Airworthiness Directives; Rolls-Royce 

Deutschland Ltd & Co KG 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for all 

Rolls-Royce Deutschland Ltd & Co KG 

Model Trent 1000–AE3, Trent 1000– 

CE3, Trent 1000–D3, Trent 1000–G3, 

Trent 1000–H3, Trent 1000–J3, Trent 

1000–K3, Trent 1000–L3, Trent 1000– 

M3, Trent 1000–N3, Trent 1000–P3, 

Trent 1000–Q3, Trent 1000–R3, Trent 

7000–72, and Trent 7000–72C engines. 

This proposed AD was prompted by 

reports of cracked intermediate pressure 

compressor (IPC) shaft assembly front 

air seals. This proposed AD would 

require an inspection of the affected IPC 

shaft assembly for cracking and, 

depending on the results of the 

inspection, repetitive inspections or 

replacement of the IPC shaft assembly 

front air seals, as specified in a 

European Union Aviation Safety Agency 

(EASA) AD, which is incorporated by 

reference. The FAA is proposing this 

AD to address the unsafe condition on 

these products. 

DATES: The FAA must receive comments 

on this NPRM by December 13, 2024. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

continuing airworthiness information 

(MCAI), any comments received, and 

other information. The street address for 

Docket Operations is listed above.
