Repeals Section 2(c) of SL 2020-19 (pertaining to initial appointments of members of the Southeast Airport Authority [Authority]). Makes conforming changes to Section 2(b) of SL 2020-19 to remove references to Section 2(c). Changes the term of members appointed to the Authority from two to four years. Increases the amount of term left when a member is appointed to the Authority to fill a vacancy from one year to two years for that appointment to count as a term for the purposes of term limits. 

Directs that the terms of the current members of the Authority will expire on December 31, 2023. Sets a schedule for appointments commencing on January 1, 2024, as follows: (1) three registered voters of the City of Laurinburg appointed by the Mayor of the City, one of whom will serve for a term of one year, one of whom will serve for a term of two years, and one of whom will serve for a term of three years; (2) three registered voters of the Town of Maxton appointed by the Mayor of the Town, one of whom will serve for a term of one year, one of whom will serve for a term of two years, and one of whom will serve for a term of three years; (3) one registered voter of Scotland County appointed by the Chair of the Board of Commissioners, who will serve for a term of four years; and (4) the Scotland County Economic Development Director, who will serve as an ex officio nonvoting member. Allows for each of these appointees to be appointed to two successive four-year terms when their initial terms expire. Specifies that the initial terms do not count towards term limits. Allows (but does not require) any of the current Authority members to be reappointed to the Authority as part of the January 1, 2024, schedule. 

Amends Section 4 of SL 2020-19 to remove the requirement that the procedures pertaining to the sale of property of cities and towns as set forth in Article 12 of GS Chapter 160A apply to the Authority’s sale, lease, or other disposal of property. Authorizes the Authority to sell property by public sale or by negotiated private sale. Maintains that any sale of real property by the Authority be approved by the City of Laurinburg City Council, Town of Maxton Town Council, and Scotland County Board of Commissioners.
