Aircraft and Airports - As enacted, specifies that a joint board established by two municipalities and two counties pursuant to an interlocal agreement for the purpose of operating an airport is vested with all the powers, rights, duties, and privileges of a regional airport authority. - Amends TCA Title 42, Chapter 5.

SB 1611 would allow a joint board formed by two municipalities and two counties (via an interlocal agreement) to operate an airport with the same legal authority as a regional airport authority under Tennessee law. The bill grants such boards all powers, rights, and duties of a regional airport authority, recognizing them as public entities that can file a charter with the state to formalize their corporate status. It specifies that governance details (like member terms and board composition) must be set in the interlocal agreement, not in state code. This change directly affects local governments forming such airport partnerships, streamlining their operational authority without requiring new state legislation.
