Swift Fuels has slashed the price of its UL94 Avgas supplemental type certificate (STC) by more than 75 per cent to $100 for each piston aircraft.

The company is also rolling-out its new ‘Forever’ Avgas STC certificate to all Avgas STC purchasers, which entitles the holder to receive all future Avgas STCs issued by the FAA to Swift Fuels for specific aircraft and piston engines at no extra charge. Buyers will get the UL94 unleaded Avgas STC and the Forever Avgas STC certificate together for $100.

Swift Fuels is offering the Forever Avgas STC certificate to every pilot and aircraft owner in the US and Canadian piston fleet, including all high compression/100-octane demanding aircraft for $100. International sales of Forever Avgas STC certificates are set to begin in approximately 90 days.

Its goal is to fully replace 100LL leaded Avgas with a 100-octane unleaded Avgas alternative. Its proprietary engine and flight-testing programmes are ongoing, working to achieve FAA-certification on its premium 100-octane unleaded fuel in close collaboration with the FAA and various OEMs.

In the months ahead, Swift will require every aircraft in the US and Canadian fleet to purchase an STC in order to fly its 100-octane unleaded Avgas. But, if clients buy a Forever Avgas STC now, they will already own the certificate entitling them to all future Avgas STCs from Swift Fuels for their aircraft. All purchasers of a Forever Avgas STC from Swift Fuels will receive a private registration certificate.

CEO Chris D'Acosta says: “The price of the Forever Avgas STC is at its lowest point now, but pricing is expected to rise an additional $50 each year going forward. So, we encourage our supporters to lock-in all future Avgas STCs from Swift Fuels at the current low price. The Forever Avgas STC programme will allow Swift Fuels to 'illuminate the pathway to fleet-wide approval' for pilots as we rollout our 100-octane unleaded Avgas to replace 100LL.

“While there is no assurance that the FAA will grant such a certification to every aircraft, Swift Fuels is actively pursuing its FAA certification programme for engines and airframes across the North American fleet, with expectations of replacing 100LL on a global scale within three to five years.”

Swift Fuels has been the only company in the US selling unleaded Avgas for piston-engine powered aircraft since 2015. UL94 unleaded Avgas is currently FAA-approved for over two-thirds of the US piston fleet, over 125,000 aircraft. Its Avgas STC programme already covers many hundreds of piston engine and airframe combinations, and its STC programme has big plans to expand to a fleet-wide solution to fully replace 100LL.
