The National Air Transportation Association (NATA) joins industry and governmental partners in welcoming the FAA’s issuance of Supplemental Type Certificates (STCs) approving the use of GAMI’s 100 octane unleaded avgas (G100UL) in all spark-ignition piston aircraft and engines in the General Aviation (GA) fleet.
These STCs represent a major step forward for the future of unleaded avgas. Distribution of G100UL is expected to phase in gradually, with 2024 as the targeted timeframe to begin broader availability.
The phaseout of lead won’t be complete until 100UL is commercially at scale. In the meantime, the industry/governmental Eliminate Aviation Gasoline Lead Emissions (EAGLE) Initiative is expected to continue as fuel producers such as Swift Fuels, Phillips66/Afton Chemical, and Lyondell Chemical/VP-Racing also pursue approvals. NATA supports EAGLE’s goal of a lead-free future for U.S. piston-engine aircraft by the end of 2030, without adversely impacting the GA fleet’s safe and efficient operation – which includes maintaining 100LL availability across the country during the transition.
“The National Air Transportation Association (NATA) is pleased to see this advancement toward an unleaded Avgas future take shape. As G100UL becomes commercially available over the next few years, we look forward to continuing to develop infrastructure support, resources and training for airports, FBOs, and other refueling operators, as well as guidance on unleaded avgas conversion considerations now for fuel service providers to support its safe and effective rollout. NATA congratulates GAMI on this achievement,” stated NATA President and CEO Curt Castagna.
G100UL information, including cost, is available at GAMI.com.
