Two unleaded fuels are going through the STC process, and one is going through the FAA’s Fleet Authorization process. What guidance is available for using these fuels in experimental aircraft?

Owner/operators of Experimental Amateur-Built aircraft are responsible for reviewing available data and determining suitability for their individual aircraft.

  • For those interested in using fuel(s) approved via the STC process, we recommend contacting the STC holder directly. These fuel developers own relevant data and plan to make it available to interested parties upon request.
  • Guidance and data packages for the fuel being evaluated under the FAA’s Fleet Authorization via PAFI program will be provided to the owners of E-AB aircraft by the FAA.

Please stay engaged with EAGLE and our partners for updates and resources. For more information, please see The Two FAA Pathways to Approve the Use of Unleaded Aviation Fuel.
