WASHINGTON, D.C. – General Aviation Manufacturers Association (GAMA) President and CEO, Pete Bunce, issued the following statement regarding the FAA’s approval of Supplemental Type Certificates (STC) to allow General Aviation Modifications Inc.’s (GAMI) 100-octane unleaded fuel (G100UL) to be used in every general spark-ignition engine and every airframe powered by those engines:
“As we continue to work towards a safe and reliable transition to an unleaded future state for piston-engine aircraft, FAA issuance of a broader STC for GAMI’s G100UL is a significant milestone. Manufacturers look forward to having an opportunity to understand the composition and performance of this new fuel to support commercialization and use as a viable replacement for 100LL.”
The type certification process and issuance of the STCs means the FAA has found that engines and aircraft operating on the new G100UL fuel continue to be compliant with the applicable airworthiness safety standard requirements such as Part 33 for engines and Part 23 for airplanes. Manufacturers’ understanding of a new fuel is essential to continued operational safety regulatory responsibilities and business activities such as customer technical support, warranty services and consideration of incorporating the new fuel in manufacturer issued service and approval documents and new production engines and aircraft.
As a stakeholder in the Eliminate Aviation Gasoline Lead Emissions (EAGLE) initiative, GAMA supports the general aviation industry’s ultimate goal of a practical unleaded avgas that can replace 100LL and will continue to support Afton/Phillips66 and Lyondell/VP-Racing advancing through the EAGLE fleet authorization testing and evaluation process and supporting deployment of Swift Fuels and GAMI working through the FAA STC certification process.
