This action amends Class E airspace at Omak Airport, Omak, WA. Decommissioning of the Nondirectional Radio Beacon (NDB) has made this action necessary. This action also makes a minor change to the legal description in reference to the Class E airspace extending upward from 4,500 feet Mean Sea Level (MSL). This improves the safety and management of Instrument Flight Rules (IFR) operations at the airport.
