(1) The board of county commissioners of any county is authorized to set aside a special sinking fund in the office of the county treasurer for the payment of revenue bonds authorized by and issued under the provisions of this article and for the payment of interest due on such bonds, but the general income of the county shall not be pledged for the payment of the principal of the bonds and interest thereon. The county treasurer shall deposit in said sinking fund all rents, royalties, fees, rates, and charges derived from or rendered by the airport or airport facilities, and the board of county commissioners of any county may pledge any or all moneys in said sinking fund to the payment of bonds authorized under this article and the interest thereon.

(2) Revenue bonds issued under this article shall not constitute an indebtedness of the county within the meaning of any constitutional or statutory limitations. Each bond issued under this article shall recite in substance that said bond, including interest thereon, is payable solely from the revenues pledged to the payment thereof and that said bond does not constitute a debt of the county within the meaning of any constitutional or statutory limitations.
