Amendment of Class D and Class E Airspace; Aspen, CO

This action modifies Class E airspace designated as an extension at Aspen-Pitkin County Airport/Sardy Field, Aspen, CO, and removes the part-time NOTAM language from the legal description. This action also amends Class E airspace extending upward from 700 feet above the surface and removes the Class E 1,200 foot airspace. Also, this action updates the airport's geographic coordinates, and replaces the term Airport/Facility Directory with Chart Supplement in the Class D airspace and Class E surface airspace legal descriptions. These changes are necessary to accommodate airspace redesign for the safety and management of instrument flight rules (IFR) operations at the airport.
