The Federal Aviation Administration (FAA) released the draft Transition Plan to Unleaded Aviation Gasoline for public comment. Comments on this notice must be submitted on or before March 13, 2026. The National Association of State Aviation Officials (NASAO), as a member of the Eagle Initiative, encourages state aviation officials, pilots, aircraft owners, and aviation stakeholders to review and comment on the FAA’s draft plan, which highlights many of the technical, regulatory, and logistical challenges in shifting from 100LL to unleaded fuel. (See: https://www.faa.gov/aircraft/draft_docs/pubs)
The draft plan emphasizes the efforts underway toward the national goal for the phase-out of 100LL, targeting 2030 for the contiguous United States (2032 for Alaska). The draft plan provides a framework for the transition and describes phases of transition, anticipated timelines, fuel-authorization pathways, and steps that airports, pilots, and aircraft owners will need to consider as unleaded fuels continue to enter the market in the coming years.
The FAA notes that stakeholder feedback will further inform the transition moving forward. Stakeholder participation will also support transparency and keep safety at the forefront.
The transition to unleaded fuel will shape general aviation for decades, and input from the general aviation community remains central to assuring a safe and smart transition.
