Small gasoline-powered aircraft are the single largest source of lead emissions in the United States, as other major sources—such as automobile gasoline—have already been addressed. Lead, a highly toxic substance that can cause a range of adverse health effects in humans, is added to aviation gasoline to meet the performance and safety requirements of a sizable portion of the nation’s gasoline-powered aircraft fleet.
ACRP Research Report 284: Transitioning to Unleaded Aviation Gasoline: A Guide and Tools, produced by TRB’s Airport Cooperative Research Program, summarizes the general steps and best practices that airports can follow when seeking to supply unleaded aviation gasoline. The report also highlights important sources of information to assist with planning and implementing an airport’s transition to unleaded aviation fuel.
The project that produced ACRP Research Report 284 also released Understanding the Transition to Unleaded Aviation Gasoline: A Primer, which is intended to provide airports with concise information about the transition to unleaded aviation gasoline, based on the latest information available at the time of its preparation in January 2025. It is suggested that those interested in transitioning to unleaded aviation gasoline read the Primer first.
