States that participate in the State Block Grant Program assume responsibility for administering Airport Improvement Program (AIP) grants at airports classified as "other than primary" airports — that is, nonprimary commercial service, reliever, and general aviation airports. Each State is responsible for determining which locations will receive funds for ongoing project administration.

FAA began this program in 1989 with three States: Illinois, Missouri, and North Carolina. AIR-21 authorized up to 10 States to participate. Title 49 United States Code Section 47128 contains program requirements.
