Hawker Beechcraft Global Customer Support will make available factory-completed Hawker 400XPR and 800XPR business jets, the company announced here in Dubai. Through the program, GCS plans to help customers locate and buy airframes for installation of XPR program updates and any other customer-specific options. Consequently, customers who do not currently own a Hawker 400 or 800 can easily acquire a completed XPR with full factory warranty and support.

 The Hawker 400XPR offers improved range and airfield performance, while reducing noise footprint and emissions by replacing their existing Pratt & Whitney Canada PW308A engines with new Williams International FJ44-4A-32 dual FADEC high-bypass turbofans, The upgrade also includes to installation of winglets and an optional modernized flight deck.

Capable of producing 5,000 pounds of thrust but flat-rated at 4,600, the Hawker 800XPR’s new TFE731-50R turbofans create a robust interstage turbine temperature margin that translates into improved reliability and performance. Through the incorporation of 70 design and material improvements, the TFE731-50R delivers a 7-percent reduction in specific fuel consumption while increasing maintenance intervals.

Separately, Hawker Beechcraft GCS plans to increase Hawker 400XPR scheduled production rates following a sellout of previously planned production. The company expects to gain certification of the new Williams engines and Hawker winglets for the mods at the end of June 2012.
