The Proposal

The FAA is considering an amendment to 14 CFR part 71 by establishing a Class E airspace at Mariposa-Yosemite Airport, Mariposa, CA. New RNAV (GPS) SIAPs at Mariposa-Yosemite Airport requires additional controlled airspace extending upward from 700 feet above the surface. This airspace is needed to contain aircraft and provide adequate controlled airspace for aircraft executing the new IFR approaches at Mariposa-Yosemite Airport, Mariposa, CA.

Class E airspace designations are published in paragraph 6005 of FAA Order 7400.9M dated August 30, 2004, and effective September 16, 2004, which is incorporated by reference in 14 CFR part 71.1. The Class E airspace designation listed in this document would be published subsequently in this Order.

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 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 would not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
