# SUPPLEMENTARY INFORMATION:

## History

On January 24, 2000, the FAA proposed to amend Title 14 Code of Federal Regulations, part 71 (14 CFR part 71) by revising a Class E airspace extension at Englewood, CO, in order to accommodate a revised SIAP to the Centennial Airport, Englewood, CO. This amendment provides a small amount of additional Class E4 airspace at Englewood, CO, to meet current criteria standards associated with the SIAP. The FAA establishes Class E airspace where necessary to contain aircraft transitioning between the terminal and en route enivornments. The intended effect of this proposal is designed to provide for the safe and efficient use of the navigable airspace. This rule promotes safe flight operations under Instrument Flight Rules (IFR) at the Centennial Airport and between the terminal and en route transition stages.

                    The area will be depicted on aeronautical charts for pilot reference. The coordinates for this airspace docket are based on North American Datum 83. Class E airspace areas designated as an extension to a Class D airspace area, are published in paragraph 6004, of FAA                           ( print page 33751)                        Order 7400.9G dated September 1, 1999, and effective September 16,1999, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designation listed in this document will be published subsequently in the Order.                

## The Rule

This amendment to Title 14 Code of Federal Regulations, part 71 (14 CFR part 71) revise Class E airspace extension at Englewood, CO, in order to accommodate a revised SIAP to the Centennial Airport, Englewood, CO. This amendment provides a small amount of additional Class E4 airspace at Englewood, CO, to meet current criteria standards associated with the SIAP. The FAA establishes Class E airspace where necessary to contain aircraft transitioning between the terminal and en route environments. This rule is designed to provide for the safe and efficient use of the navigable airspace and to promote safe flight operations under Instrument Flight Rules (IFR) at the Centennial Airport and between the terminal and en route transition stages.

The area will be depicted on aeronautical charts for pilot reference. The coordinates for this airspace docket are based on North American Datum 83. Class E airspace areas designated as an extension to a Class D airspace area, are published Paragraph 6004, of FAA Order 7400.9G dated September 1, 1999, and effective September 16, 1999, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designation listed in this document will be published subsequently in the Order.

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. It, therefore: (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, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
