Preparing for the day when 100LL avgas will be outlawed in America, the FAA has selected two unleaded fuels — one from Swift Fuels and one from Shell — for further testing.
FAA Selects Two Unleaded Fuels for Testing
Key Takeaways:
- The FAA has selected two unleaded fuel candidates, one each from Swift Fuels and Shell, for further testing as part of the Piston Aviation Fuel Initiative (PAFI).
- Flight trials and rig testing for these fuels will begin this summer and run through 2018 to develop an ASTM standard, aiming for a drop-in replacement for 100LL avgas.
- This initiative prepares the general aviation industry for the eventual ban on leaded fuel, which currently powers approximately 167,000 U.S. aircraft.
