Briefing: July 2018
In June, the FAA put on hold its flight testing for the Piston Aviation Fuels Initiative (PAFI) unleaded 100LL replacement fuels program. The FAA said it would assess issues related to the differences between the two PAFI fuels and 100LL. Both fuel producers, Shell and Swift, are currently evaluating options to mitigate the impacts that these differences will present in fuel production, distribution, and operation in the GA fleet, said the FAA. The FAA also said it will also assess alternative fuels developed outside the PAFI program. Meanwhile, General Aviation Modifications Inc. (GAMI) said its close to completing testing on its own 100-octane unleaded fuel. GAMI sidestepped PAFI in favor of a more streamlined STC approval process.
