G100UL is not commercially available as the plaintff argues. It has not been approved for my airplane under its TC. I cannot legally purchase and use this in my aircraft under its TC. To use it I must purchase a license to use it, making this a private club purchase, similar to the old alcohol rules in Utah. Can’t buy a drink unless you join the private club.
To purchase this, the manufacturer sells a supplement to my TC to allow me to join its club to purchase its product. This is not commercial availability, but private, restricted availability. I can use Swift Fuel without an STC and mogas because I bought an STC decades ago which allows me to buy and use any mogas meeting the specification, not restricted to a specific factory or process. Mogas and SwiftFuel are commercially available.
From Russ:
Are you sure your mogas STC covers Swift?
