# ACTION:

Notice of proposed rulemaking (NPRM).

# SUMMARY:

This action proposes to amend the Class D and Class E airspace areas at Idaho Falls, ID, by changing the name of the airport to Idaho Falls Regional Airport, and adjusting the geographic coordinates of the airport.

## The Proposal

The FAA is proposing an amendment to Title 14 Code of Federal Regulations (14 CFR) part 71 by amending the Class D and Class E airspace areas to change the airport name from Fanning Field to Idaho Falls Regional Airport, and also would adjust the geographic coordinates of the airport to be in concert with the FAA's Aeronautical Products office. Also, existing Class E airspace area extending upward from 700 feet above the surface at Idaho Falls Regional Airport would be adjusted to accommodate aircraft using the new RNAV (RNP) standard instrument approach procedures, and would enhance the safety and management of aircraft operations at the airport.

Class D and Class E airspace designations are published in paragraph 5000, 6002, 6004 and 6005, respectively, of FAA Order 7400.9U, dated August 18, 2010, and effective September 15, 2010, which is incorporated by reference in 14 CFR 71.1. The Class D and Class E airspace designations listed in this document will be published subsequently in this Order.

The FAA has determined 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 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 the 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 amends controlled airspace at Idaho Falls Regional Airport, Idaho Falls, ID.
