## Abstract

This action revises Class D and E airspace at Allen Army Airfield (AAF), AK. The United States Army has decided to staff the Allen AAF air traffic control tower (ATCT) part time. The Class D and E airspace is being revised in order to align Class D airspace effective times to match ATCT hours of operation. The current title of the airspace described in FAA Order 7400.9P is also changing to reflect current guidance in FAA Order 7400.2E. This rule results in the revision of Class D and E airspace at Allen AAF, Delta Junction, AK.
