Swift Enterprises and Electroair have signed a testing agreement, in which Swift’s Cessna 150 will be fitted with an Electroair Direct Fire Ignition System as the company continues development on its alternative for 100LL.
For the last five years, Swift has been developing 100SF, a high-octane unleaded replacement for 100LL that meets Grade UL102 of the newly-published ASTM D7719 Standard Specification for High-Octane Unleaded Test Fuel. Swift’s Cessna 150, which has a four-cylinder Continental O-200-A engine, will be fitted with an Electroair Direct Fire Ignition System to further augment the increased fuel economy experienced by using 100SF, according to Swift officials. The Continental O-200-A can — and has — flown, unmodified, on UL102, officials said. Swift flew the Cessna 150 to AirVenture on 100% SwiftFuel, and it is being displayed outside the Innovations Center.
Electroair recently earned a Supplemental Type Certificate (STC) for a pure-electronic ignition system on all four-cylinder Lycoming aviation engines.
