Organizational Information

Unleaded Avgas Transition Aviation Rulemaking Committee (UAT ARC)

Randy Babbitt, the FAA Administrator, signed the Unleaded Aviation Gasoline Transition Aviation Rulemaking Committee (ARC) charter (PDF) on January 31, 2011, in Washington, D.C. "It's our goal to bring together all the industry stakeholders to be able to achieve the goal of a suitable fuel in a timely fashion," said Babbitt. The ARC was tasked to investigate the current issues relating to the transition to an unleaded fuel, and recommend the tasks necessary to investigate and resolve these issues.

The committee was comprised of members that encompassed all constituencies surrounding the unleaded fuel issue to include aviation trade associations, aircraft and engine manufacturers, petroleum and other fuel producers, environmental groups, the Environmental Protection Agency (EPA) and the Federal Aviation Administration (FAA). See UAT ARC membership.

Piston Alternative Fuels Initiative (PAFI)

The Piston Aviation Fuel Initiative (PAFI) was established at the request of a broad cross section of the aviation and petroleum industries and consumer representatives to develop a path forward for the identification, evaluation and deployment of the most promising unleaded replacements for 100 low lead aviation gasoline. The mission of PAFI is to evaluate candidate unleaded replacement fuels and identify those fuels best able to technically satisfy the needs of the existing aircraft fleet while also considering the production, distribution, cost, availability, environmental and health impacts of those fuels. Mounting environmental and economic pressure necessitates a transition to unleaded fuel. Unfortunately, the aviation and petroleum marketplace, in concert with existing government regulations and policies, do not support an orderly and economically viable fleet-wide transition to a new fuel or fuels, hence the need for the joint government and industry collaborative initiative known as PAFI.

PAFI Steering Group (PSG)

The purpose of the PSG is to facilitate, coordinate, expedite, promote and oversee the Piston Aviation Fuels Initiative (PAFI) based on the recommendations of the Unleaded Avgas Transition Aviation Rulemaking Committee Final Report.

Fuels Program Office (AIR-20)

The FAA created the Fuels Program Office, AIR-20, in August 2012, to lead the FAA's efforts to transition General Aviation to an unleaded avgas. This office includes the Fuels Program Branch, which will provide the "centralized certification office" concept recommended by the UAT ARC.
