ELIMINATE AVIATION GASOLINE LEAD EMISSIONS INITIATIVE

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 to eliminate the use of leaded aviation fuels for piston-engine aircraft in the United States by the end of 2030 (2032 for Alaska) without adversely impacting the safe and efficient operation of the existing GA fleet.

During the transition phase, if I load up with unleaded fuel in my aircraft at Airport A and fly to fuel at Airport B, I may have a safety issue if the fuels cannot commingle. What is EAGLE doing to test for mixing between the replacement unleaded fuels?

All currently approved unleaded fuels and those in development are safely mixable with 100LL.

Pilots and operators should always check the fuel’s specification or approval documents (i.e.- Supplemental Type Certificate, Pilots Operating Handbook, Owner’s Manual, Airplane Flight Manual etc.) with their airframe and/or engine OEM to confirm which combinations are permitted, as well as any limitations on blending with other fuels.

The ability to combine these fuels safely is critical for aircraft owners, pilots, the aviation industry, and the FAA. The FAA and industry are evaluating options to ensure safety for these fuels.
