## History 

                    On March 1, 2005, the U.S. Army requested that the FAA take action to establish R-5601F. Specifically, the requested action would provide additional airspace needed to support new high angle air-to-ground training                           ( print page 66307)                        requirements for Air Force, Navy, and Marine aircraft operating over the Falcon Bombing Range. Specifically, R-5601F would provide additional maneuvering area needed for aircraft conducting training in adjacent restricted areas R-5601B and R-5601C which are located over the West Range Target Area and the Falcon Bombing Range, respectively. This action would also enhance Fort Sill's ability to host joint training.                 

## The Proposal 

At the request of the U.S. Army, the FAA is proposing an amendment to Title 14 Code of Federal Regulations (14 CFR) part 73 to establish R-5601F adjacent to and north of R-5601B and R-5601C. Establishment of the new restricted area would provide additional airspace needed to support new high angle air-to-ground training requirements for Air Force, Navy, and Marine aircraft operating over the Falcon Bombing Range and would enhance Fort Sill's ability to host joint training. 

The FAA has determined that 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 Department of Transportation (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 proposed 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. 

## Environmental Review 

This proposal will be subjected to an environmental analysis in accordance with FAA Order 1050.1E, “Environmental Impacts: Policies and Procedures,” prior to any FAA final regulatory action.
