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.
