The governing body may levy and collect the taxes so certified at the same time and in the same manner as other taxes are levied and collected, and the proceeds of such taxes when due and as collected shall be set aside and deposited in the special account or accounts in which other revenue of the authority is deposited. An authority in a city of the first or second class or a village shall have power to certify annually to the governing body of such a city or village an additional amount of tax to be levied for airport purposes, not to exceed three and five-tenths cents on each one hundred dollars of taxable value, to be levied, collected, set aside, and deposited as specified in this subdivision, and if negotiable bonds of the authority are thereafter issued, this power shall continue until such bonds are paid in full.
