Key Takeaways:

The general aviation industry is preparing for an imminent EPA endangerment finding on leaded aviation fuel, actively developing and discussing a replacement for 100LL.
While progress has been made on unleaded fuels, a high-octane solution is still needed for a critical 30% of the fleet that accounts for 70% of flight hours.
Industry groups emphasize that the EPA's finding does not constitute a ban on 100LL; their priority is to retain its use until a universally acceptable, FAA-approved replacement is in place.
The EPA finding will establish regulatory standards for lead emissions in aviation fuel for the first time, setting a pathway for future rulemaking, though the FAA remains the final authority on aviation safety and fuel approval.

In anticipation of an imminently-expected endangerment finding from the Environmental Protection Agency (EPA) on leaded aviation fuel, the General Aviation Manufacturers Association (GAMA) hosted an industry-centric “background” briefing for aviation press on October 12. GAMA was clear from the beginning that this was an industry-only briefing and did not come under the “umbrella” of the Eliminate Aviation Gas Lead Emissions (EAGLE) initiative, described by GAMA as “a comprehensive public-private partnership consisting of aviation and petroleum industry and U.S. government stakeholders.”

Representatives from GAMA, the Aircraft Owners and Pilots Association (AOPA), Experimental Aircraft Association (EAA), and the National Air Transportation Association (NATA) participated in the discussion.
