The Center for Environmental Health (CEH) appears poised to challenge in court the National Air Transport Association’s assertion that General Aviation Modifications Inc.’s G100UL is not commercially available. “G100UL has been approved by FAA and is now in production.  There are approximately 1 million gallons available for purchase and distribution into California,” CEH’s lawyer Mark […]

The Biden administration has laid out rules for corn farmers to qualify for subsidies to supply feedstock for sustainable aviation fuel (SAF). The corn is now used to make ethanol, which is added to gasoline, but the move to electric cars will diminish that market. Ethanol can be turned into Jet A, however, and will […]

Vitol Aviation, which has more than a million gallons of General Aviation Modifications Inc. (GAMI) G100UL unleaded avgas for sale, is disputing claims by the National Air Transportation that the fuel is not ready to be sold. In a statement last week, NATA said that without a fuel specification from ASTM International, which GAMI has […]

The National Air Transport Association (NATA) says General Aviation Modifications Inc.’s (GAMI) FAA-approved G100UL is not yet “commercially available” even though the licensed manufacturer of the unleaded avgas, Vitol Aviation, has more than a million gallons of it for sale. In a statement, the organization, which represents FBOs and fuel distributors, said that because G100UL […]

Lycoming says it doesn’t think its engines are to blame for the valve seat recession problems experienced by the University of North Dakota flight training department last year after it switched to Swift Fuels’ UL94 fuel. Rather, it says in a news release (copied in full below) its analysis suggests that “under certain conditions, use […]

General Aviation Modifications Inc. founder George Braly says he thinks he knows why the University of North Dakota’s flight training program had valve seat recession issues using Swift 94UL fuel but he won’t release the details until he’s discussed it with UND and Swift. “I have to extend them that courtesy,” he said. The school […]

The FAA says engine cell testing of one of three contenders actively being considered as a replacement for 100LL avgas will begin later this year at the agency’s William J. Hughes Technical Center in Atlantic City. In a statement to AVweb, the agency said the fuel developed by a partnership between LyondellBasell Industries and VP […]

Savvy Aviation master mechanic Mike Busch is questioning the methodology of tests done by the University of North Dakota that resulted in it abandoning the use of Swift 94UL and going back to 100LL in its training fleet. The school made the switch back to leaded fuel last fall because it detected significant valve seat […]

The lawyer for a California environmental group says a court settlement that will mandate the sale of G100UL avgas will not necessarily prevent FBOs from also selling 100LL. Mark Todzo, who represents the Center for Environmental Health, clarified part of his December 2023 letter to FBOs and fuel distributors informing of the imminent commercial availability […]

Swift Fuels CEO Chris D’Acosta says a legal threat against California FBOs to sell a new-to-the-market unleaded 100-octane fuel is based on the premise that G100UL, developed by General Aviation Modifications Inc., will soon be commercially available, something he says is unlikely to happen anytime soon. In public comments and in emails to AVweb, D’Acosta claims that […]
