### 41837 Federal Register / Vol. 78, No. 134 / Friday, July 12, 2013 / Rules and Regulations

AD applies to all Sikorsky Model S–70, S–70A, and S–70C helicopters, which are restricted category helicopters derived from the military Model UH–60 helicopter. The part number (P/N) for the No. 2 crossfeed breakaway valve listed in the ‘‘Required Actions’’ section is incorrect. This document corrects that error. Also, this document contains a response to a comment received after publication of the Final Rule. In all other respects, the original document remains the same.

**DATES :**  This final rule is effective July 12, 2013. The effective date for AD 2012–23–13 (77 FR 71087, November 29, 2012) remains December 14, 2012.

**ADDRESSES :**  You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this AD, the regulatory evaluation, any comments received, and other information. The address for the Docket Office (phone: 800–647–5527) is Document Management Facility, U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC 20590.

**SUPPLEMENTARY INFORMATION :**  Airworthiness Directive 2012–23–13, Amendment 39–17269 (77 FR 71087, November 29, 2012), currently includes the following under paragraph (e)(xiii) in the Required Actions section:

(xiii) For Number 2 crossfeed breakaway valve, P/N 70307–03600–103, establish a life limit of 1,500 hours.

As published, the identification of the P/N as 70307–03600–103 is incorrect. The correct P/N is 70307–03006–103. No other part of the regulatory information has been changed; therefore, only the changed portion of the final rule is being published in the Federal Register

. Comments

After we published our Final rule; request for comments (77 FR 71087; November 29, 2012), we received a comment from one commenter.
Request

The one commenter from the manufacturer stated that the document reduced the life limit for the main and tail rotor blades but does not make any reference to the detailed internal life limited components of the blades. The commenter asked whether the AD applies only to the blade assembly P/Ns and whether the blade components were overlooked.

We do not agree that the AD should include life limits for the internal components of the blade assembly. The life limit of each main and tail rotor blade reflects the life limit of its lowest component in the Sikorsky Airworthiness Limitations technical manual. That manual does not list life limits for individual internal components. Correction of Regulatory Text

**Establishment of Class E Airspace; Parkston, SD** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Final rule.

**SUMMARY :**  This action establishes Class E airspace at Parkston, SD. Controlled airspace is necessary to accommodate new Area Navigation (RNAV) Standard Instrument Approach Procedures at Parkston Municipal Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport.

**DATES :**  Effective date: 0901 UTC, October 17, 2013. The Director of the Federal Register approves this incorporation by reference action under 1 CFR Part 51, subject to the annual revision of FAA Order 7400.9 and publication of conforming amendments.

**SUPPLEMENTARY INFORMATION :**  History

On April 30, 2013, the FAA published in the Federal Register a notice of proposed rulemaking (NPRM) to establish Class E airspace for the Parkston, SD, area, creating controlled airspace at Parkston Municipal Airport (78 FR 25232) Docket No. FAA–2012– 1282. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received. Class E airspace designations are published in paragraph 6005 of FAA Order 7400.9W dated August 8, 2012, and effective September 15, 2012, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designations listed in this document will be published subsequently in the Order.

The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) Part 71 by establishing Class E airspace extending upward from 700 feet above the surface within a 6.8-mile radius of Parkston Municipal Airport, Parkston, SD, to ensure that required controlled airspace exists to contain new standard instrument approach procedures at the airport. Controlled airspace enhances the safety and management of IFR operations at the airport.

The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that only affects air traffic procedures and air navigation, it is certified that this rule, when promulgated, does not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.


### 41838 Federal Register / Vol. 78, No. 134 / Friday, July 12, 2013 / Rules and Regulations

The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the U.S. Code. Subtitle 1, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency’s authority. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it establishes controlled airspace at Parkston Municipal Airport, Parkston, SD.

Environmental Review

The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with FAA Order 1050.1E, ‘‘Environmental Impacts: Policies and Procedures,’’ paragraph 311a. This airspace action is not expected to cause any potentially significant environmental impacts, and no extraordinary circumstances exist that warrant preparation of an environmental assessment.
