## Abstract

This action removes Colored Federal airway, R-50, and amends Alaskan VOR Federal airway, V-319, and United States Area Navigation (RNAV) Routes T-219 and T-269 in Alaska. The modifications are necessary due to the planned decommissioning of the Nanwak Non- Directional Beacon (NDB) and Distance Measuring Equipment (DME) in Mekoryuk, AK, which provides navigation guidance for portions of the affected routes. The Nanwak NDB/DME (AIX) is to be decommissioned effective June 17, 2021 due to the high cost of maintenance.
