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.

The FAA William J. Hughes Technical Center is the nation’s premier air transportation system laboratory. The Tech Center’s workforce conducts test and evaluation, verification and validation, and sustainment of the FAA’s full range of aviation systems, and develops scientific solutions to current and future air transportation safety challenges by conducting applied research and development. Additionally, the Center provides the gateway for National Airspace System upgrades, improvements, and operational sustainment.
