Notice of proposed rulemaking (NPRM).
Summary
This action proposes to modify the Class E airspace designated as a surface area, modify the Class E airspace extending upward from 700 feet above the surface, and remove the Class E airspace extending upward from 1,200 feet above the surface at Mammoth Lakes Airport, Mammoth Lakes, CA. Additionally, this action proposes administrative amendments to update the airport's existing Class E airspace legal descriptions. These actions would support the safety and management of instrument flight rules (IFR) operations at the airport.
