The FAA has issued a Supplemental Type Certificate (STC) for Swift Fuels' 100R unleaded avgas to be used in Cessna 172R/S Skyhawks with Lycoming IO-360-L2A engines.
This initial approval is described as a breakthrough and the beginning of Swift Fuels' broader program.
Swift Fuels aims for a global replacement of 100LL within three to five years, positioning 100R as the preferred fuel to eliminate toxic lead from avgas.
The company is actively working with industry and OEMs on further FAA certifications and ASTM International specifications for expanded use.
