Amendment of Class D and E Airspace, Falmouth, MA

This action amends Class E airspace designated as an extension at Cape Cod Coast Guard Air Station, (formerly Otis ANGB), Falmouth, MA, as the Otis TACAN has been decommissioned, requiring airspace reconfiguration. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at the airport. This action also updates the geographic coordinates of the airport in the existing Class D and E airspace areas, as well as Falmouth Airpark, Barnstable Municipal Airport-Boardman/Polando Field, Chatham Municipal Airport, Martha's Vineyard Airport, (formerly Martha's Vineyard Municipal Airport), and the BOGEY LOM.
