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

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

1. The authority citation for Part 71 

continues to read as follows:

40120; E.O. 10854, 24 FR 9565, 3 CFR, 1959– 

1963 Comp., p. 389. 

§ 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.

Mount Airy-Surry County Airport, NC

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-mile 

radius to 15.3 miles north of the Mount AirySurry County Airport.
