Honeywell has delivered the first batch of 32 TFE731-50R engines destined for Hawker’s new 900XP midsize business jet. This latest version of the engine, derived from the TFE731-50 powering the Dassault Falcon 900DX, continues a series that began with certification of the first TFE731 in 1972. Since then more than 11,000 TFE731 engines have been built. Honeywell says the -50 offers a 6 percent improvement in thrust-specific fuel burn “and will help the Hawker 900XP deliver a reduced noise signature.”

The 4,750-pound-thrust -50R (flat rated to 90.5 degrees F/ISA +17.5 degrees C) brings a 7 percent range improvement for ISA-day takeoffs and up to a 24 percent increase for hot-and-high takeoff over the TFE731-5BR powering the Hawker 800XP.
