Sierra Industries Brings Hawker 400XPR to Orlando

Sierra Industries and Clifford Development have formed a joint venture called NewJETz to develop a Williams International FJ44-4 engine (3,600 lbs. of thrust) retrofit program. The retrofit will power legacy Cessna Citation 550 and 560 series jets, including the Citation V, Bravo, Ultra and Encore. The new modification is called eVolution, and NewJETz will also offer owners of these aircraft avionics and other upgrades.
