Airport Improvement Program

The Airport Improvement Program is a United States federal grant program that provides funds to public-use airports to help improve safety and efficiency. Improvement projects relate to runways, taxiways, ramps, lighting, signage, weather stations, NAVAIDs, land acquisition, and some areas of planning. The program is managed by the Federal Aviation Administration.^[1]

Funding for the program is provided by the Airport and Airway Trust Fund, which receives revenue from taxes on airplane tickets sold to the public and a tax on aviation fuel. The federal grant may cover between 75 and 95 percent of the eligible costs, depending on the type of improvement and the size of the airport. Both commercial and general aviation airports are eligible for AIP grants.^[2]

Grants awarded for Fiscal Year 2017 totaled $3,332,800,000.^[3]

History

The program was established under the Airport and Airway Improvement Act of 1982 (Pub. L. 97–248) by combining the Planning Grant Program (PGP) and Airport Development Air Program (ADAP) into a single normally multi-year grant.^[4][5] In 1994, the provisions of the Airport and Airway Improvement Act of 1982 were codified in subchapter I of chapter 471 of title 49, United States Code.
