SUPPLEMENTARY INFORMATION: 

History

    On May 20, 2011, the FAA published in the Federal Register a notice 
of proposed rulemaking to modify controlled airspace at Fort Huachuca, 
AZ (76 FR 29179). 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 D and E airspace designations are published in paragraph 
5000, 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 Part 71.1. The Class D and 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 modifying Class D airspace, and Class E airspace designated 
as an extension to Class D surface area, and airspace extending upward 
from 700 feet above the surface, at Fort Huachuca, AZ. The FAA's 
biennial review of the airspace found additional controlled airspace 
necessary for the safety and management of aircraft departing and 
arriving under IFR operations at Fort Huachuca, Sierra Vista Municipal 
Airport-Libby Army Airfield. This action updates the geographic 
coordinates to coincide with the FAA's aeronautical database, and 
changes the airport name from Fort Huachuca, Libby AAF/Sierra Vista 
Municipal Airport, to Fort Huachuca, Sierra Vista Municipal Airport-
Libby Army Airfield. This action is necessary for the safety and 
management of IFR operations.
    The FAA has determined 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 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 FAA's 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 creates 
additional controlled airspace at Fort Huachuca, Sierra Vista Municipal 
Airport-Libby Army Airfield, Fort Huachuca, AZ.
