Question 1

What is FAA’s role in fuel’s approval?

Eagle · Accepted Answer

The FAA approves the use of fuel under one of the two approval pathways, either under the Fleet Authorization via the Piston Aviation Fuels Initiative (PAFI) testing program, or under the traditional STC/TC pathway. Once the FAA approves the use of a new fuel, it is up to the open market to deploy the fuel in terms of production, distribution, airport/FBO availability, and owner/operator use. Ultimately, the open market will determine the commercial viability of new unleaded fuel or fuels that replace 100LL.
