Action
Final rule.
Summary
This action amends the Class D airspace and Class E airspace area designated as an extension to a Class D surface area and establishes Class E airspace extending upward from 700 feet above the surface at St. Louis Regional Airport, Alton/St. Louis, IL. This action is the result of an airspace review caused by the decommissioning of the outer marker to runway 29 at St. Louis Regional Airport. The geographic coordinates of the airport are also being updated to coincide with the FAA's aeronautical database.
