## Abstract

This action removes a provision in part 71 that excludes from Class A airspace, that portion of U.S. domestic airspace that overlies the Santa Barbara and Farallon Islands and the airspace south of latitude 25[deg]04'00" North (overlying and in the vicinity of the Florida Keys). The effect of this provision is that the airspace from 18,000 feet MSL up to and including Flight Level (FL) 600 (within the excluded areas) is classified as Class G (uncontrolled) airspace which limits the flexibility for air traffic control operations.
