The FAA has approved an additional 611 certified piston aircraft engines to run on GAMI’s G100UL high octane unleaded avgas in an FAA-approved model list that was posted on Thursday. With the announcement, about 70 percent of existing engines in service are now able to use the fuel, which received FAA approval itself in July. “This is a very bullish sign that the FAA is continuing to honor their commitment to move unleaded avgas forward as fast as possible,” AOPA fuel consultant Paul Millner said in a story published on the organization’s website. Another approved list in which those engines are mated to approved airframes will be coming soon.
