## Abstract

This notice modifies Class D airspace and Class E airspace at Terre Haute, IN. An analysis of the controlled airspace required for the instrument approach procedures for Terre Haute International-Hulman Field Airport, in light of the recent runway extension for that airport, have resulted in the need to modify the Class D airspace and the Class E airspace extension to the Class D airspace. The purpose of this action is to provide adequate controlled airspace for the instrument approach procedures and flight operations at the airport. This action increases the radius of the Class D airspace and modifies the Class E airspace extension, incorporating the increased radius, for this airport.
