## Abstract

This final rule updates the designated mountainous areas in the State of Alaska. Regulations currently designating mountainous areas in Alaska were established in 1956. Since that time, we have concluded that areas previously considered non-mountainous should be expanded, and two areas previously designated mountainous should be considered non-mountainous. This final rule will allow aircraft operating in certain non-mountainous areas to fly at altitudes acceptable for the actual topography of the area.
