SUPPLEMENTARY INFORMATION: The NRC received a petition for rulemaking dated February 18, 2014, submitted by Diane Curran, Harmon, Curran, Spielberg & Eisenberg, L.L.P., and Mindy Goldstein, Turner Environmental Law Clinic, Emory Law School, on behalf of 34 Environmental Organizations (ADAMS Accession No. ML14071A382). The petition was docketed as PRM–51–31. The NRC published a notice of receipt of PRM–51–31 in the Federal Register on May 1, 2014 (79 FR 24595). On June 26, 2014, the petitioner submitted to the NRC a document characterized as an ‘‘amended petition’’ for rulemaking (ADAMS Accession No. ML14177A660). The petitioner requests the NRC to ‘‘add to the record of the February 18, 2014 Petition the observations made by Chairman Macfarlane in her dissenting comments’’ on the NRC staff document designated COMSECY–13–0030—‘‘Staff Evaluation and Recommendation for Japan Lessons-Learned Tier 3 Issue on Expedited Transfer of Spent Fuel.’’ 1 In its February 18, 2014, petition (ADAMS Accession No. ML14071A382), the petitioner asserted that COMSECY– 13–0030 constituted new and significant information under the National Environmental Policy Act (NEPA). On this basis, the petitioner requested that the NRC take the following actions, which the petitioner asserts is necessary to ensure the NRC’s compliance with NEPA: • Republish for public comment the 2013 Revised License Renewal Generic Environmental Impact Statement, the Environmental Impact Statements for all new reactors; and the Environmental Assessments for all new certifications of standardized reactor designs; • Duly modify the NRC’s regulations that make or rely on findings regarding the environmental impacts of spent fuel storage during reactor operation, including Table B–1 in subpart A of appendix B in part 51 of Title 10 of the Code of Federal Regulations (10 CFR) and all regulations approving standardized reactor designs. The NRC does not consider the June 26, 2014, document to be an amendment to the February 18, 2014, petition as the petitioner does not request that the NRC take any rulemaking actions that were not otherwise requested in the February 18, 2014, petition. Therefore, the NRC will consider the June 26, 2014, document to be a supplement to PRM– 51–31, and accordingly, will include it in the docket for PRM–51–31 (NRC– 2014–0055). The NRC is publishing this notice for information only and is not requesting public comment. Dated at Rockville, Maryland, this 17th day of July 2014. For the Nuclear Regulatory Commission. Annette L. Vietti-Cook, Secretary of the Commission.

Discussion On April 2, 1998, we issued AD 98– 07–07, Amendment 39–10426 (63 FR 18119, April 14, 1998), for all RR RB211–535E4 and RB211–535E4–B turbofan engines. AD 98–07–07 superseded AD 96–13–04 and required removing LP fuel system tube assemblies, P/N UL16692 and AE709623–1, and installing LP fuel system tube assembly, P/N 163521538. AD 98–07–07 resulted from reports of fuel line rupture on one of the flexible fuel tube assemblies installed in accordance with AD 96–13–04. We issued AD 98–07–07 to prevent high volume fuel leaks and reported fuel collection inside the engine nacelle, which could result in an uncontrolled engine fire. Actions Since AD 98–07–07 Was Issued Since we issued AD 98–07–07, Amendment 39–10426 (63 FR 18119, April 14, 1998), additional fuel leaks have occurred in LP fuel system tube assemblies resulting in engine in-flight shutdowns. Also since we issued AD 98–07–07, the European Aviation Safety PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 Agency has issued AD 2014–0123, dated May 15, 2014, which requires replacing affected fuel tube assemblies. Relevant Service Information We reviewed RR Service Bulletin No. RB.211–73–H131, with Supplement, dated May 10, 2013 and RR NonModification Service Bulletin No. RB.211–73–E355, Revision 3, May 10, 2013. The service information describes procedures for removing and installing LP fuel system tube assemblies. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require removing LP fuel tube assemblies, P/N UL16692, AE709623–1, 163521538, and 163521545 from service. Costs of Compliance We estimate that this proposed AD affects 500 engines installed on airplanes of U.S. registry. We also estimate that it would take about 7.33 hours per engine to comply with this proposed AD. The average labor rate is $85 per hour. Required parts cost about $10,000 per engine. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $5,311,525. 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. We are 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 proposed 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 We have determined that this proposed AD would not have federalism E:\FR\FM\24JYP1.SGM 24JYP1 Federal Register / Vol. 79, No. 142 / Thursday, July 24, 2014 / Proposed Rules 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) Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), (3) Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction, and (4) 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. (d) Unsafe Condition List of Subjects in 14 CFR Part 39 (g) Alternative Methods of Compliance (AMOCs) Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by removing airworthiness directive (AD) 98–07–07, Amendment 39–10426 (63 FR 18119, April 14, 1998), and adding the following new AD: ■ Rolls-Royce plc: Docket No. FAA–2014– 0433; Directorate Identifier 94–ANE–39– AD. pmangrum on DSK3VPTVN1PROD with PROPOSALS (a) Comments Due Date We must receive comments by September 22, 2014.

SUMMARY: We propose to supersede airworthiness directive (AD) 98-07-07,

[[Page 42990]]

which applies to all Rolls-Royce plc (RR) RB211-535E4 and RB211-535E4-B 
turbofan engines. AD 98-07-07 requires removing certain part number (P/
N) low-pressure (LP) fuel filter-to-high-pressure (HP) fuel pump tube 
assemblies and installing flexible LP fuel filter-to-HP fuel pump tube 
assemblies. Since we issued AD 98-07-07, we received additional reports 
of fuel leaks that have resulted in a number of engine in-flight 
shutdowns. This proposed AD would expand the applicability of AD 98-07-
07 to include the RB211-535E4-C-37 turbofan engine. We are proposing 
this AD to prevent loss of fuel supply to the engine, which could lead 
to an in-flight shutdown of one or more engines, loss of thrust 
control, and damage to the airplane.

Discussion

    On April 2, 1998, we issued AD 98-07-07, Amendment 39-10426 (63 FR 
18119, April 14, 1998), for all RR RB211-535E4 and RB211-535E4-B 
turbofan engines. AD 98-07-07 superseded AD 96-13-04 and required 
removing LP fuel system tube assemblies, P/N UL16692 and AE709623-1, 
and installing LP fuel system tube assembly, P/N 163521538. AD 98-07-07 
resulted from reports of fuel line rupture on one of the flexible fuel 
tube assemblies installed in accordance with AD 96-13-04. We issued AD 
98-07-07 to prevent high volume fuel leaks and reported fuel collection 
inside the engine nacelle, which could result in an uncontrolled engine 
fire.

Actions Since AD 98-07-07 Was Issued

    Since we issued AD 98-07-07, Amendment 39-10426 (63 FR 18119, April 
14, 1998), additional fuel leaks have occurred in LP fuel system tube 
assemblies resulting in engine in-flight shutdowns. Also since we 
issued AD 98-07-07, the European Aviation Safety Agency has issued AD 
2014-0123, dated May 15, 2014, which requires replacing affected fuel 
tube assemblies.

Relevant Service Information

    We reviewed RR Service Bulletin No. RB.211-73-H131, with 
Supplement, dated May 10, 2013 and RR Non-Modification Service Bulletin 
No. RB.211-73-E355, Revision 3, May 10, 2013. The service information 
describes procedures for removing and installing LP fuel system tube 
assemblies.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require removing LP fuel tube assemblies, P/
N UL16692, AE709623-1, 163521538, and 163521545 from service.

Costs of Compliance

    We estimate that this proposed AD affects 500 engines installed on 
airplanes of U.S. registry. We also estimate that it would take about 
7.33 hours per engine to comply with this proposed AD. The average 
labor rate is $85 per hour. Required parts cost about $10,000 per 
engine. Based on these figures, we estimate the cost of this proposed 
AD on U.S. operators to be $5,311,525.

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.
    We are 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 proposed 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

    We have determined that this proposed AD would not have federalism

[[Page 42991]]

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) Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska to the extent 
that it justifies making a regulatory distinction, and
    (4) 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing airworthiness directive (AD) 
98-07-07, Amendment 39-10426 (63 FR 18119, April 14, 1998), and adding 
the following new AD:

Rolls-Royce plc: Docket No. FAA-2014-0433; Directorate Identifier 
94-ANE-39-AD.

(a) Comments Due Date

    We must receive comments by September 22, 2014.

(b) Affected ADs

    This AD supersedes AD 98-07-07, Amendment 39-10426 (63 FR 18119, 
April 14, 1998).

(c) Applicability

    This AD applies to all Rolls-Royce plc (RR) RB211-535E4-37, 
RB211-535E4-B-37, and RB211-535E4-C-37 turbofan engines with low-
pressure (LP) fuel filter-to-high-pressure (HP) fuel pump tube 
assembly, part number (P/N) UL16692, AE709623-1, 163521538, or 
163521545, installed.

(d) Unsafe Condition

    This AD was prompted by reports of fuel leaks that have resulted 
in a number of engine in-flight shutdowns. We are issuing this AD to 
prevent loss of fuel supply to the engine, which could lead to an 
in-flight shutdown of one or more engines, loss of thrust control, 
and damage to the airplane.

(e) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.
    (1) After the effective date of this AD, remove from service all 
LP fuel filter-to-HP fuel pump tube assemblies, P/Ns UL16692, 
AE709623-1, 163521538, and 163521545, at the next part removal or 
during the next engine shop visit, whichever occurs first.
    (2) Reserved.

(f) Definition

    For the purpose of this AD, an ``engine shop visit'' is the 
induction of an engine into the shop for maintenance.

(g) Alternative Methods of Compliance (AMOCs)

    The Manager, Engine Certification Office, may approve AMOCs for 
this AD. Use the procedures found in 14 CFR 39.19 to make your 
request.
