### 14382 Federal Register / Vol. 75, No. 57 / Thursday, March 25, 2010 / Proposed Rules

The Proposal

The FAA is considering an amendment to Title 14, Code of Federal Regulations (14 CFR) part 71 to amend Class E airspace at Mount Airy, NC to provide controlled airspace required to support the SIAPs for Mount Airy-Surry County Airport. The existing Class E airspace extending upward from 700 feet above the surface would be modified for the safety and management of IFR operations.

Class E airspace designations are published in Paragraph 6005 of FAA order 7400.9T, signed August 27, 2009, and effective September 15, 2009, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designation listed in this document will be published subsequently in the Order.

The FAA has determined that this proposed regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore, (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 will only affect air traffic procedures and air navigation, it is certified that this proposed rule, when promulgated, would not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. 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. This proposed 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 proposed regulation is within the scope of that authority as it would amend Class E airspace at Mount Airy-Surry County Airport, Mount Airy, NC.
List of Subjects in 14 CFR Part 71

Airspace, Incorporation by reference, Navigation (Air). The Proposed Amendment In consideration of the foregoing, the Federal Aviation Administration proposes to amend 14 CFR Part 71 as follows:

**PART 71—DESIGNATION OF CLASS A, B, C, D, AND E AIRSPACE AREAS; AIR**  **TRAFFIC SERVICE ROUTES; AND REPORTING POINTS** 

1. The authority citation for Part 71 continues to read as follows:

**§ 71.1 [Amended]**

2. The incorporation by reference in 14 CFR 71.1 of Federal Aviation Administration Order 7400.9T, Airspace Designations and Reporting Points, signed August 27, 2009, effective September 15, 2009, is amended as follows:
Paragraph 6005 Class E Airspace Areas Extending Upward from 700 feet or More Above the Surface of the Earth.

That airspace extending upward from 700 feet above the surface within a 9-mile radius of the Mount Airy-Surry County Airport and within 3.9 miles each side of the 353 ° bearing from the airport extending from the 9-mileradius to 15.3 miles north of the Mount AirySurry County Airport.
