The past two years have seen significant progress in transitioning the general aviation fleet to unleaded fuel, and the coming months are expected to be equally active.
Timeline of avgas discussions over the past year:
February 2022
Aviation and petroleum industry leaders and the FAA establish the joint EAGLE (Eliminate Aviation Gasoline Lead Emissions) program, focused on safely eliminating the use of leaded aviation fuel by the end of 2030 without adversely affecting the safety and operation of the existing piston-engine fleet. EAGLE supports each of the four fuel developers in their efforts.
September 2022
FAA issues an Approved Model List Supplemental Type Certificate (AML STC) for GAMI's G100UL unleaded avgas.
October 2022
EPA releases their proposed finding of endangerment regarding lead emissions from piston aircraft.
December 2022
Congress allocates $10 million for continued testing and evaluation of unleaded fuel to move GA to a fleetwide, lead-free fuel solution by no later than 2030.
January 2023
A coalition of seven aviation stakeholder organizations, including EAA, submitted comments to the EPA’s proposed endangerment finding of lead in aviation gasoline.
January 2023
EAA, along with other general aviation associations, signed on to a letter that opposed a Washington state House of Representatives bill that would ban the sale of leaded avgas in Washington by 2024.
July 2023
AirVenture 2023 Avgas Update
October 2023
A coalition of aviation stakeholder organizations issued the following joint statement regarding the U.S. Environmental Protection Agency’s (EPA) endangerment finding on lead in aviation gasoline (avgas).
November 2023
General aviation industry members of the Eliminate Aviation Gasoline Lead Emissions (EAGLE) initiative are applauding the news of the first unleaded fuel candidate to successfully pass the most rigorous Piston Aviation Fuels Initiative (PAFI) initial detonation and 150-hour engine durability test phase, and continued progress toward an unleaded future.
