The Federal Aviation Administration (FAA) released a draft Transition Plan to Unleaded Aviation Gasoline for public comment, outlining the technical, regulatory, and logistical considerations associated with moving away from 100LL. The FAA is seeking expert feedback from across the aviation community, with comments due by March 13.
The draft plan establishes national transition targets of 2030 for the contiguous United States and 2032 for Alaska, and describes transition phases, anticipated timelines, fuel authorization pathways, and considerations for airports and operators as unleaded fuels enter the market. The FAA emphasized that stakeholder input will help shape the final plan and ensure safety remains at the forefront of the transition.
NATA is actively reviewing the plan alongside industry partners. Curt Castagna, NATA President and CEO and Industry Chair of EAGLE, noted that the transition to unleaded avgas will have lasting operational and economic implications and emphasized that meaningful industry input is essential to ensure the transition remains safe, practical, and aligned with real-world operations. NATA encourages general aviation airports and aviation businesses—including fuel producers, distributors, FBOs, and charter operators—to participate in the public comment process and share insights informed by operational experience and on-the-ground realities.
