# AGENCY:

Federal Aviation Administration (FAA), DOT.

# ACTION:

Notice of proposed rulemaking.

# SUMMARY:

This action proposes to modify Class E airspace at Twin Falls, ID.

This action would enhance the safety and management of aircraft operations at the airport. This action would also amend the airport name to Twin Falls Joslin Field-Magic Valley Regional, from Twin Falls-Sun Valley Regional, Joslin Field.

## The Proposal

The FAA is proposing an amendment to Title 14 Code of Federal Regulations (14 CFR) part 71 by modifying Class E airspace at Twin Falls, ID. Controlled airspace is necessary to accommodate aircraft using the new VOR SIAP at Twin Falls Joslin Field-Magic Valley Regional, Twin Falls, ID. This action would enhance the safety and management of aircraft operations at Twin Falls Joslin Field-Magic Valley Regional, Twin Falls, ID.

Class E airspace designations are published in paragraph 6005 of FAA Order 7400.9S, signed October 3, 2008, and effective October 31, 2008, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designation listed in this document will be published subsequently in this 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. Therefore, this proposed 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 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 U.S. Code. Subtitle 1, Section 106, describes the authority for 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 would add additional controlled airspace at Twin Falls Joslin Field-Magic Valley Regional, Twin Falls, ID.

## The Proposed Amendment

Accordingly, pursuant to the authority delegated to me, 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 14 CFR part 71 continues to read as follows:

2. The incorporation by reference in 14 CFR 71.1 of the FAA Order 7400.9S, Airspace Designations and Reporting Points, signed October 3, 2008, and effective October 31, 2008 is amended as follows:
