The transition away from leaded aviation gasoline affects every link in the general aviation supply chain—from fuel producers and distributors to airports, FBOs, pilots, aircraft owners, and mechanics. To support industry-wide understanding, the Eliminate Aviation Gasoline Lead Emissions (EAGLE) initiative now offers tools and data to help stakeholders track the transition and assess its scope, scale, and impact.
The new Interactive Toolkit, available at flyEAGLE.org, offers regularly updated insights into the U.S. piston fleet, fuel infrastructure, airport fuel availability, 100LL production and logistics, sales volumes, per-capita data, and more. The toolkit is searchable, sortable, visual—and most importantly—designed to clarify how the transition is unfolding across the national aviation landscape.
What’s available now:
- Airport Fuel Availability –U.S. airports offering 100LL, UL94, mogas, or G100UL
- Refinery & Distribution Map – Current avgas production and distribution network
- Sales Volume & History – State-by-state and national fuel usage back to the 1960s
- Piston Aircraft Registry – Ability to search by airframe or engine to assess fleet eligibility
- Mechanics & IA Capacity – Data to understand workforce availability for compliance
- Per Capita Fuel Usage – Information to identify heavy-use states like Alaska, Montana, and Wyoming
Piston Aviation Fuel Initiative (PAFI) Progress
The site also provides a summary of the FAA’s Piston Aviation Fuels Initiative (PAFI) fleet authorization process and the testing status of the LyondellBasell/VP Racing high-octane unleaded aviation gasoline (UL100E). The data highlights progress across key testing areas, including detonation and performance, durability, flight testing, and materials compatibility with components such as O-rings, OEM wing tanks, and paint. This information is also available at flyEAGLE.org/resources.
The site will be updated as new data is available.

Eliminate Aviation Gasoline Lead Emissions (EAGLE) is a comprehensive government-industry initiative consisting of the aviation and petroleum industries and U.S. government stakeholders, and a wide range of other constituents and interested parties, all working toward the transition to lead-free aviation fuels for piston-engine aircraft by the end of 2030 without compromising the safety or economic health of the general aviation industry.
