. **SUPPLEMENTARY INFORMATION :**  I. Background

On November 8, 2013 (78 FR 67225; NRC–2009–0096), the NRC published for public comment a proposed rule to amend its regulations for MC&A of SNM. Also on November 8, 2013 (78 FR 67224; NRC–2013–0195), the NRC published for public comment the proposed guidance documents that discuss acceptable methods that licensees may use to prepare and implement their MC&A plans and how the NRC will review and inspect these plans. The public comment period for the proposed rule and the proposed guidance closes on February 18, 2014.

The goal of this rulemaking is to revise and consolidate the MC&A requirements in order to update, clarify, and strengthen them. The proposed amendments add new requirements that would apply to NRC licensees who are authorized to possess SNM in a quantity greater than 350 grams. II. Public Meeting

To facilitate the understanding of the public and other stakeholders of these issues and the submission of comments, the NRC staff plans to hold a public meeting on December 10, 2013, from 1:00 p.m. to 5:00 p.m. (EST), in Rockville, Maryland. The meeting notice can be accessed through the NRC’s public Web site at http:// meetings.nrc.gov/pmns/mtg. The final agenda and the meeting materials will be posted no fewer than 10 days prior to the meeting at this Web site.

In addition, members of the public may also participate in the meeting via teleconference or Webinar. Information for the teleconference and Webinar is available in the meeting notice, which can be accessed through the NRC’s public Web site at http:// meetings.nrc.gov/pmns/mtg

. Participants must register at the Internet link in the meeting notice to participate in the Webinar. To register in advance for the teleconference, please contact Thomas Young at 301–415–5795 (email: Thomas.Young@nrc.gov ).
Dated at Rockville, Maryland, this 22nd day of November, 2013.

### 71533 Federal Register / Vol. 78, No. 230 / Friday, November 29, 2013 / Proposed Rules

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to supersede airworthiness directive (AD) 2007–03– 02 for all Rolls-Royce Deutschland (RRD) Tay 620–15, Tay 650–15, and Tay 651–54 turbofan engines. AD 2007–03– 02 requires an ultrasonic inspection (UI) of low-pressure (LP) compressor fan blades for cracks on certain serial number (S/N) Tay 650–15 engines. AD 2007–03–02 also requires, for all Tay 611–8, 620–15, Tay 650–15, and Tay 651–54 engines, initial and repetitive UIs of LP compressor fan blades. AD 2007–03–02 also requires, for Tay 650– 15 and Tay 651–54 engines, UIs of LP compressor fan blades whenever the blade set is removed from one engine and installed on a different engine. Since we issued AD 2007–03–02, we received a report of an additional engine failure due to multiple fan blade separation. This proposed AD would require additional inspections for the affected engines and removal of the Tay 611–8 engine from the applicability of this AD. We are proposing this AD to prevent failure of the LP compressor fan blade, engine failure, and damage to the airplane.

**DATES :**  We must receive comments on this proposed AD by January 28, 2014.

**ADDRESSES :**  You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:

• Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.

• Fax: 202–493–2251.

Discussion

On January 22, 2007, we issued AD 2007–03–02, Amendment 39–14913 (72 FR 3936, January 29, 2007) (‘‘AD 2007– 03–02’’) for certain RRD Tay 611–8 and Tay 620–15 turbofan engines with LP compressor module, part number (P/N) M01100AA or P/N M01100AB, installed, and Tay 650–15 and Tay 651– 54 turbofan engines with LP compressor module, P/N M01300AA or P/N M01300AB, installed. AD 2007–03–02 requires UI of LP compressor fan blades for cracks on certain S/N Tay 650–15 engines. AD 2007–03–02 also requires, for all Tay 611–8, 620–15, 620–15/20, Tay 650–15, Tay 650–15/20, and Tay 651–54 engines, initial and repetitive UIs of LP compressor fan blades. AD 2007–03–02 also requires, for Tay 650– 15 and Tay 651–54 engines, UIs of LP compressor fan blades whenever the blade set is removed from one engine and installed on a different engine. AD 2007–03–02 resulted from a report that a set of LP compressor fan blades failed before reaching the LP compressor fan blade full published life limit. We issued AD 2007–03–02 to prevent LP compressor fan blades from failing due to blade root cracks, leading to uncontained engine failure and damage to the airplane.

Actions Since AD 2007–03–02 Was Issued

Since we issued AD 2007–03–02, we received reports of additional engine failures. Also since we issued AD 2007– 03–02, the European Aviation Safety Agency issued AD 2013–151R2, dated September 2, 2013, which requires UI, and replacement if found cracked, of affected LP compressor fan blades. Also since we issued AD 2007–03–02, RRD issued ANMSB TAY–72–A1442, Revision 5, dated May 31, 2013 which removed the Tay 611–8 engine from the list of applicable engines.

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 requires a UI of LP compressor fan blades for cracks for all 620–15, Tay 650–15, and Tay 651–54 engines. This proposed AD would also require accomplishing the actions specified in the service information described previously. Costs of Compliance

We estimate that this proposed AD would affect about 52 engines installed on airplanes of U.S. registry. We also estimate that it would take about 4 hours per engine to remove and inspect an LP compressor blade set. The average labor rate is $85 per hour. Prorated parts life will cost about $11,750 per engine. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $628,680. 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


### 71534 Federal Register / Vol. 78, No. 230 / Friday, November 29, 2013 / Proposed Rules

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

We have determined that this proposed AD would not have federalism 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. List of Subjects in 14 CFR Part 39

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) 2007–03–02, Amendment 39–14913 (72 FR 3936, January 29, 2007), and adding the following new AD:
Rolls-Royce Deutschland Ltd & Co KG: Docket No. FAA–2006–24777; Directorate Identifier 2006–NE–19–AD. (a) Comments Due Date

The FAA must receive comments on this AD action by January 28, 2014.
