MDT Aeronautics Division Airport Loan and Grant Program

The MDT Aeronautics Division offers grants and low-interest loans to support airport and aviation facility projects throughout Montana. Eligibility is open to publicly owned and public-use airports and facilities. Funding can cover up to 100% of project costs, either already underway or planned, focusing on improvements like pavement maintenance, construction, lighting, and fuel systems. The program draws funds from a 4.5¢/gal tax on general aviation fuel, although the total funds available may vary yearly due to tax revenue fluctuations. Applications are accepted until November 15 annually, with a review process conducted by the Aeronautics Board in December and decisions made in a public meeting in January.
