Amends SL 1971-419, as amended, increasing the membership of the Stanly County Airport Authority (Authority) to seven total members, now including one additional member appointed by the Stanly County Board of Commissioners (Board) and one additional member currently serving as a county commissioner. Establishes staggered terms for appointees. Replaces previous oath requirements to instead require oaths of office to be administered pursuant to state law. Eliminates the Board's authority to appoint an additional commissioner to serve as a voting alternate to the sole commissioner previously appointed. Revises the powers and duties of the Authority to now authorize the Authority to lease property or facilities, or contract for airport operations or activities, for terms of up to 30 years (was, 25 years) within the parameters of existing law.
