EAGLE – Unleaded Aviation Fuel

In 2021, leaders of aviation and petroleum groups committed to an initiative laying out a clear plan to transition piston-engine aircraft to lead-free aviation fuels by the end of 2030 – the Eliminate Aviation Gasoline Lead Emissions (EAGLE) initiative. EAGLE is an industry and government partnership to expand and accelerate the actions and policies necessary for a viable high-octane unleaded replacement for the current 100 octane low-lead aviation gasoline (100LL), without compromising the existing U.S. transportation infrastructure system, aviation safety, and the economic and broader public benefits of general aviation.

The EAGLE initiative is structured around four key pillars – Supply Chain, Infrastructure and Deployment; Research, Development and Innovation; Unleaded Fuel Evaluation and Authorization; and Regulation, Policy and Programmatic Activities. These activities, which will require full government support, provide the foundation toward safe unleaded aviation fuels for piston-engine aircraft. Groups committed to the EAGLE initiative include NATA (National Air Transportation Association), Aircraft Owners and Pilots Association (AOPA), American Association of Airport Executives (AAAE), American Petroleum Institute (API), Experimental Aircraft Association (EAA), General Aviation Manufacturers Association (GAMA), National Business Aviation Association (NBAA), and Vertical Aviation International (VAI).

“Even though 2030 is the target to achieve a fleet authorization, lead-free alternative to 100LL, we hope to obtain that goal much sooner with industry and government working together. As we collectively move toward a scalable solution, NATA and our members are continuing to demonstrate leadership in keeping a safety first focus on infrastructure support, as well as on the development of resources and training for airports, FBOs, and other refueling operators.” – NATA President and CEO Curt Castagna
