## Abstract

This action amends Class E airspace at Poplar Municipal Airport, Poplar, MT. The airport was moved 1.5 Nautical Miles (NM) to the northeast. Controlled airspace is necessary to accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures at Poplar Municipal Airport, Poplar, MT. This improves the safety and management of Instrument Flight Rules (IFR) operations at the airport. This also corrects the airport name from Poplar Airport.
