A 100-octane unleaded aviation gasoline made by Swift Fuels, approved by the FAA under supplemental type certificates in September 2024 and widened in July 2026 to about 1,200 engine and 1,600 airframe models, roughly 56% of the aircraft that burn 100LL by Swift's count. Sold at ten airports by mid-2026, with airports in 29 states expected to switch from UL94 during 2026 and 2027. Owners need Swift's certificate; UL94 certificate holders receive it at no charge.

The families and series are those the FAA's certificate listing names; a certificate written for "all spark-ignition engines" names none and covers them all. Whether one aircraft is covered depends on its exact model and engine, which the certificate's approved model list settles; the aircraft's own page says what applies to it.
