## Abstract

This action revises the Class D airspace at Lake Hood, AK, Elmendorf Air Force Base (AFB), AK, and Merrill Field, AK, as well as the Class E airspace (designated as surface areas) at Elmendorf AFB, AK, and Merrill Field, AK. The revision of the Anchorage, Alaska, Terminal Airspace Area segment boundaries affecting Lake Hood, AK, Elmendorf AFB, AK, and Merrill Field, AK, made this action necessary. With the exception of the internal boundary between Merrill Field, AK, and Lake Hood, AK, airspace areas, the adoption of this rule will result in the alignment of Class D airspace to coincide with the revised Anchorage Terminal Airspace segment boundaries, eliminating chart clutter and confusion between segment, Class D boundaries, and Class E boundaries. The adoption of this rule will also align the Elmendorf AFB, AK, and Merrill Field, AK, Class E airspace areas (designated as surface areas) with the Class D boundaries.
