The Eliminate Aviation Gasoline Lead Emissions organization has released its third and final examination of what it sees as the key elements of the industry and government quest for an alternative to 100LL. This one looks at the role ASTM International, a private sector consensus standards organization, plays in that pursuit. Two of three candidate fuels for replacing 100UL, from Lyondell/Basell and Swift Fuels, are attempting to secure an ASTM fuel specification while General Aviation Modifications Incorporated has decided not to deal with ASTM. GAMI’s G100UL has been granted an FAA STC with an approved model list that includes all spark ignition piston engines in certified aircraft and all certified aircraft except helicopters. It is being sold at two California airports. The full EAGLE examination of ASTM involvement appears unedited below.
EAGLE Discusses ASTM Involvement In Unleaded Fuel Process
Key Takeaways:
- The Eliminate Aviation Gasoline Lead Emissions (EAGLE) organization's latest report examines ASTM International's role in the development and approval of alternatives to 100LL aviation fuel.
- Two candidate unleaded fuels, from Lyondell/Basell and Swift Fuels, are pursuing ASTM fuel specifications for their approval.
- General Aviation Modifications Incorporated (GAMI) has bypassed ASTM, instead securing an FAA STC for its G100UL fuel, which is approved for nearly all spark ignition piston engines and certified aircraft (excluding helicopters) and is currently available at two California airports.
