What Resources Are Available to Help Airports Transition to Unleaded Aviation Gasoline?

As outlined above, the EAGLE initiative website should serve as the primary resource for information related to the availability of unleaded aviation gasoline from the various potential fuel suppliers, as well as any safety or technical issues. Additionally, the fuel suppliers themselves are the primary source of detailed information about their products, including ASTM conformance, STC cost and coverage, and price and availability.

With respect to funding for expanding fueling infrastructure, at the time of this publication, the FAA is operating two funding programs. One of these is the Bipartisan Infrastructure Law (BIL), also known as Infrastructure Investment and Jobs Act, which provides for Airport Infrastructure Grants that can be used on sponsor-owned, revenue-producing facilities such as fuel farms (FAA 2024d).

The other program is the Airport Improvement Program (AIP), where the FAA is authorized to provide funding for aircraft fueling systems, e.g., for a new airport fuel storage tank or fuel truck (FAA 2019). While numerous conditions may apply, eligible fuel infrastructure projects generally include the installation of facilities to provide a fuel type not available at the airport at the time this document was published, which could include unleaded aviation gasoline (FAA 2019, Table D-1). Airports can contact their FAA Airports District Office for more details. Further, with the signing of the FAA Reauthorization Act (H.R. 3935) into law by President Biden on May 16, 2024, the FAA has broader authority to support transition-enabling unleaded aviation gasoline fueling infrastructure.
