## Abstract

This action amends Class D and Class E2 airspace at New Castle Airport, Wilmington, DE. This action increases the lateral dimensions of the Wilmington, DE Class D and Class E2 airspace, which are overlays, by adding a 2-mile wide, 0.2-mile long extension to the existing 4.2-mile radius, along the 008[deg] bearing from the New Castle Airport, to support instrument flight rules (IFR) operations. This action also updates language in the airspace legal description to comply with current FAA directives.
