The FAA is now reportedly investigating reports of damage to aircraft related to their use of GAMI’s G100UL unleaded fuel in California. Inspectors looked at several planes involved at Watsonville Airport south of San Francisco. Various incidents of peeling paint, leaking fuel tanks and even a bent pushrod/seized valve have been reported in various forums. […]
General Aviation Modifications Inc. has completed its own version of a 10-day simulation of a slow leak of its G100UL unleaded fuel and no paint damage resulted. In the video results below, GAMI founder and chief of engineering George Braly says the fuel was allowed to drip and evaporate on a side panel from a […]
A California A&P who has been testing the effects of GAMI’s G100UL on aircraft paint says a second round of testing has confirmed early results. But GAMI founder George Braly says his company has been unable to replicate Michael Luvara’s results. Braly said immersion tests and allowing fuel to evaporate on painted surfaces haven’t caused […]
California aviation fuel distributors say there are too many gaps in accessibility and too many questions about GAMI G100UL’s suitability for some aircraft to make it the only high-octane choice at California airports. In their response to a motion by the Center for Environmental Health for the California Superior Court to enforce the terms of […]
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 […]
