General Aviation Modifications Inc. says long-term exposure of painted aircraft surfaces to avgas with high aromatic content, like its G100UL and, potentially, 100LL is “not recommended” but “incidental contact should not cause paint to peel.” The company was responding to a video released by a California A&P who conducted his own set of material compatibility […]
G100UL unleaded fuel appears to damage aircraft paint under specific circumstances, according to a California A&P who conducted his own compatibility tests on it and 100LL. Michael Luvara also said new nitrile O-rings swelled beyond certified limits when submerged in the unleaded fuel for five to six days. GAMI recommends replacing nitrile components with those […]
Textron says it won’t add G100UL unleaded avgas to its approved fuel list until it has been more thoroughly tested. In statements released last Friday (one for singles, one for twins), the company said it won’t be giving its stamp of approval to the fuel unless and until that more comprehensive testing has been done. […]
A third fuel retailer has announced plans to sell GAMI’s G100UL unleaded avgas, and in many ways it couldn’t be farther from the existing California facilities offering the fuel. Tupelo Aviation Unlimited, in the heart of Mississippi, says it will have the high-octane lead-free alternative for retail sale in mid-January at $6.99 a gallon, 45 […]
The Eliminate Aviation Gasoline Lead Emissions (EAGLE) team has released Part 1 of a three-part series called “Clearing the Air: How Unleaded Aviation Fuel Is Gaining Approval.” Part 1 (attached below) is labeled “Understanding the STC process and why it matters to pilots and aircraft owners.” In a series of questions and answers, EAGLE attempts […]
General Aviation Modifications Inc. is inviting an operator of a wet-wing Mooney to visit Ada, Oklahoma, for a borescope inspection to assess the condition of the sealant in the tanks. “I would like to have the chance to borescope an older Mooney fuel tank that has not been converted over to a bladder,” Braly said […]
Phillips 66 will supply United Airlines with up to 8 million gallons of sustainable aviation fuel over the next seven months thanks to incentives from the State of Illinois. Phillips and United have signed a firm agreement for 3 million gallons to be delivered to O’Hare and 600,000 gallons to be delivered to LAX. The […]
A California Superior Court judge will hear arguments Jan. 28 that could result in 100LL becoming unavailable in California and replaced by GAMI’s G100UL unleaded avgas. The court will also be asked to require the four major fuel distributors serving California airports to carry G100UL. The Center for Environmental Health says it’s bringing the action […]
The Aircraft Owners and Pilots Association (AOPA) and local co-complainants in California issued a 47-page filing last week with the U.S. Department of Transportation/Federal Aviation Administration against Santa Clara County in California with the goal of re-establishing the availability of 100 low lead (100LL) aviation fuel at Reid-Hillview Airport (KRHV). The new filing asks the […]
The Eliminate Aviation Gasoline Lead Emissions (EAGLE) initiative posted a warning today (posted below in italics) for pilots regarding concern over misfuelling as new unleaded fuels of varying types and octane levels are starting to make their way to market. It cautions pilots to ensure their aircraft—particularly those requiring high-octane fuels—are not misfueled with “the […]
