## Abstract

This action amends the legal description of the Chicago Midway Airport Class C airspace area. Currently, the legal description uses the Runway 31L localizer course to define the southeast boundary of Chicago Midway's Class C airspace outer ring (that area between 5 and 10 nautical miles [NM]). Since the legal description was published, the Chicago Midway Airport added another runway to the outside of Runway 31L, making the old Runway 31L the new Runway 31C. To keep the Class C airspace area boundaries unchanged, a correction to the legal description must be made. This action will make the necessary correction by changing ``Chicago Midway 31L localizer course'' to read ``Chicago Midway 31C localizer course.''
