Aircraft and Airports - As introduced, increases, from 30 days to 30 business days, the amount of time before the start of a fiscal year that a joint board composed of public agencies overseeing a county or municipal airport has to submit its total expenditures to be made to the governing bodies of its constituent public agencies. - Amends TCA Title 42.

HB 1389 amends Tennessee law to extend the deadline for airport authorities to report annual spending. It changes the requirement from submitting airport expenditure reports within 30 calendar days to 30 business days before the start of a new fiscal year. This applies directly to joint boards managing county or municipal airports, which oversee spending for public agencies operating those facilities. The change is procedural, providing more time for reporting without altering financial requirements or policy substance.
