• The FAA released its final Transition Plan to Unleaded Aviation Gasoline.
• The plan aims to eliminate leaded avgas use by the end of 2030 outside Alaska.
• Three high-octane candidates are being tested: GAMI G100UL, Swift Fuels 100R and LyondellBasell/VP Racing UL100.
• Aircraft may require individual modifications to use unleaded avgas.

The FAA's plan may indicate a significant shift in the general aviation industry's fuel landscape, which could have implications for aircraft owners, manufacturers, and fuel suppliers. The transition to unleaded avgas suggests a focus on environmental sustainability and safety, which could benefit the industry in the long term, but may also pose challenges and costs for some stakeholders.
