Honeywell Green Jet Fuel Powers the First Single-Engine Turboprop Flight

Honeywell’s Green Jet Fuel™ was used to power the first single-engine turboprop flight on a Texas Turbines Conversions, Inc.-operated Cessna Caravan 208B at EAA’s 2012 AirVenture air show in Oshkosh, Wisconsin.  The aircraft’s Honeywell TPE331-12JR turboprop engine was fueled with a 50/50 blend of petroleum-based fuel (Jet A) and Green Jet Fuel made from the inedible plant camelina, which met all of the specifications for Jet A fuel and did not require any modifications to the aircraft or engine. 

Based on life-cycle analyses, during the flight from Texas Turbine’s headquarters in Celina, Texas to Oshkosh, the fuel provided a net reduction in greenhouse gas emissions of 34% compared to pure Jet A. 

Texas Turbines retrofitted the Cessna Caravan 208B with the 900 SHP Honeywell TPE331 engine to provide substantially improved performance for climb, speed or cruise fuel burn compared to the current production Caravan.  This retrofit is certified for both the Caravan 208, Grand Caravan 208B and is certified for wheels, floats and flight-into-known-icing (FIKI).
