A new report published by the National Academies of Sciences, Engineering, and Medicine Transportation Research Board says multiple mitigation strategies are necessary to reduce lead emissions from piston aircraft. The study, "Options for Reducing Lead Emissions from Piston-Engine Aircraft," was conducted by a ten-person committee in response to a congressional request laid out in the FAA Reauthorization Act of 2018. The committee’s stated goals were to assess existing non-leaded fuel alternatives to aviation gasoline, ambient lead concentrations at and around GA airports and mitigation measures to reduce those ambient lead concentrations.
