Summary

The FAA Administrator must use a competitive process to make cost-sharing cooperative agreements with organizations or consortia to develop, mature, and test certifiable CLEEN aircraft and engine technologies and jet fuels for civil airplanes. CLEEN means technologies that continuously reduce energy use, emissions, and noise. The Administrator must set performance goals to cut fuel burn, emissions, and noise. At least 2 of the agreements must include a small business (as defined in section 3 of the Small Business Act (15 U.S.C. 632)) if that business’s proposal meets FAA Acquisition Management System rules and required technology readiness levels, as the Administrator decides.
