Modification of Class E Airspace; Ralph Wien Memorial Airport, Kotzebue, AK

This action updates a notice of proposed rulemaking (NPRM) published by the FAA in the Federal Register on November 24, 2025, proposing to modify the Class E airspace area designated as a surface area (Class E2 airspace area) and Class E airspace extending upward from 700 feet above the surface (Class E5 700-foot (ft) airspace area) to optimize instrument flight procedure (IFP) containment at the Ralph Wien Memorial Airport, Kotzebue, AK. This proposal supports the safety and management of instrument flight rules (IFR) operations at the airport. The proposal has been updated based on amendments to four IFPs.
