Approach Procedures (SIAP) at Helena Regional Airport. The FAA is 
taking this action to enhance the safety and management of aircraft 
operations at Helena Regional Airport, Helena, MT. Also, this action 
makes a minor correction to the airspace description.

SUPPLEMENTARY INFORMATION: 

History

    On August 21, 2007, the FAA published in the Federal Register a 
notice of proposed rulemaking to amend Class E airspace at Helena, MT 
(72 FR 46584). This action would improve the safety of IFR aircraft 
executing this new LOC/BC-C SIAP approach procedure at Helena Regional 
Airport, Helena, MT. Interested parties were invited to participate in 
this rulemaking effort by submitting written comments on the proposal 
to the FAA. No comments were received.
    Class E airspace designations are published in paragraph 6005 of 
FAA Order 7400.9R signed August 15, 2007, and effective September 15, 
2007, 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 establishing Class E airspace at Helena, MT. Additional 
controlled airspace is necessary to accommodate IFR aircraft executing 
a new LOC/BC-C SIAP approach procedure at Helena Regional Airport, 
Helena, MT
    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. 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 Helena Regional Airport, Helena, MT.
