Proposed Amendment of Class E Airspace; Dillon, MT

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: This action proposes to modify Class E airspace at Dillon 
Airport, Dillon, MT. Controlled airspace is necessary to accommodate 
aircraft using new Area Navigation (RNAV) Global Positioning System 
(GPS) standard instrument approach procedures at Dillon Airport. This 
action also would make an adjustment to the geographic coordinates of 
the airport. The FAA is proposing this action to enhance the safety and 
management of aircraft operations at Dillon Airport, Dillon, MT.

DATES: Comments must be received on or before April 30, 2012.

ADDRESSES: Send comments on this proposal to the U.S. Department of

The Proposal

    The FAA is proposing an amendment to Title 14 Code of Federal 
Regulations (14 CFR) part 71 by modifying Class E airspace extending 
upward from 700 feet above the surface at Dillon Airport, Dillon, MT. 
Controlled airspace is necessary to accommodate aircraft using the new 
RNAV (GPS) standard instrument approach procedures at Dillon Airport. 
The geographic coordinates of the airport also would be updated to 
coincide with the FAA's aeronautical database. This action would 
enhance the safety and management of aircraft operations at Dillon 
Airport.
    Class E airspace designations are published in paragraph 6005, of 
FAA Order 7400.9V, dated August 9, 2011, and effective September 15, 
2011, 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 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 would create additional controlled airspace at Dillon Airport, 
Dillon, MT.
    This proposal will be subject to an environmental analysis in 
accordance with FAA Order 1050.1E. ``Environmental Impacts: Policies 
and Procedures'' prior to any FAA final regulatory action.
