The Piper PA-31-350 Navajo Chieftain aircraft has twin Lycoming TIO-540-J2BD engines and is being used in the Piston Aviation Fuels Initiative (PAFI) phase 2 testing for engine handling, hot fuel, and cooling climb tests. The test engine is instrumented to measure and collect performance data of PAFI fuels in comparison to the currently approved 100 low-lead (100LL) aviation gasoline.
