Amendment of Class D and Class E Airspace; Eugene, OR, and Corvallis, OR
This action amends Class E airspace designated as an extension, and Class E airspace extending upward from 700 feet above the surface at Mahlon Sweet Field Airport, Eugene, OR, to accommodate airspace redesign for the safety and management of Instrument Flight Rules (IFR) operations at the airport. Corvallis Municipal Airport is removed from the Mahlon Sweet Field Airport regulatory text by creating a stand-alone airspace designation for the airport. Additionally, this action updates the airport reference points for these airports in Class D and E airspace, as well as removes the Notice to Airmen (NOTAM) requirement noted in Class E surface area airspace.
