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

This action withdraws the final rule, technical amendment published in the Federal Register on April 25, 2017. In that action, the FAA amended Class E Airspace at Aspen Pitkin County/Sardy Field, Aspen, CO, and Pueblo Memorial Airport, Pueblo, CO. The FAA has determined that withdrawal of the final rule, technical amendment is warranted since a change in the geographic coordinates of the airports will affect the charted boundaries of the airspace, and therefore should be considered under the full rulemaking process.
