Proposed Establishment of Class E Airspace; Portland, ME

This proposed rule would establish Class E airspace at Portland International Jetport, Portland, Maine, that coincides with the hours that the associated radar approach control facility is not in operation. Since the Portland Class C airspace is predicated on an operational air traffic control tower (ATCT) serviced by a radar control approach facility (TRACON), Class E airspace must be defined for the hours when that facility is not in operation. This proposal would not change the designated boundaries or altitudes of the Portland Class C airspace, but only establish the necessary Class E airspace to provide sufficient controlled airspace for those aircraft operating under instrument flight rules during the hours when the Portland ATCT and TRACON are not in operation.
