The FAA has given the nod to UL100E, the unleaded aviation field for piston-engine aircraft developed by LyondellBasell Industries/VP Racing, to advance to full-scale engine and flight testing.
The most common suggestion I have received concerning the future of unleaded avgas is that there is a need for two grades of fuels, not just one.
AOPA President Mark Baker flew the Baron for one hour with G100UL feeding the left engine and 100LL in the right. He said the performance of the two engines was nearly identical and “the Baron flew beautifully.”
The U.S. Environmental Protection Agency (EPA) has given a $776,636 grant to the California Department of Public Health that will “provide technical assistance to general aviation airports in California in disadvantaged communities to support the transition from leaded aviation gasoline (avgas) to unleaded avgas.”
The final endangerment finding does not ban or impose restrictions on the use, sale, distribution, dispensing, and availability of leaded fuel.
One of the most common questions our oils expert receives is from pilots wondering why general aviation is in the same spot regarding unleaded avgas as it was 25 years ago.
Diamond Aircraft and Austro Engine anticipate increasing the availability of ASTM D7566 SAF blends as a “drop-in” fuel for general aviation in the coming years and plans to release the entire fleet for this fuel mix by the end of 2025.
The new refueling mat protects general aviation aircraft from scratches and leaks while refueling.
As the quest to find an unleaded replacement for 100LL continues, why isn’t the government and industry getting behind a fuel that’s already been tested and approved?
