Start Preamble


Federal Aviation Administration (FAA), DOT.


Final rule.


This action will amend Class E airspace at Alamosa, CO. Additional controlled airspace is necessary to accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) at San Luis Valley Regional Airport/Bergman Field. This will improve the safety of Instrument Flight Rules (IFR) aircraft executing the new RNAV GPS SIAP at San Luis Valley Regional Airport/Bergman Field, CO.


Effective Date: 0901 UTC, March 12, 2009. 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.

On October 28, 2008, the FAA published in the Federal Register a notice of proposed rulemaking to establish additional controlled airspace at Alamosa, CO, (73 FR 63912). Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received. With the exception of editorial changes, this rule is the same as that proposed in the NPRM.

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 part 71.1. The Class E airspace designations listed in this document will be published subsequently in that Order.

The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) part 71 by Start Printed Page 2351amending the Class E airspace at Alamosa, CO. Additional controlled airspace is necessary to accommodate IFR aircraft executing a new RNAV (GPS) approach procedure at San Luis Valley Regional Airport/Bergman Field, Alamosa, CO.

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 will only affect air traffic procedures and air navigation, it is certified that this rule, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. The FAAs authority to issue rules regarding aviation safety is found in Title 49 of the U.S. Code. Subtitle 1, Section 106 discusses 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 additional controlled airspace at San Luis Valley Regional Airport/Bergman Field, Alamosa, CO.
