The Learjet 40XR has a higher takeoff gross weight than the basic 40. Improvements to the TFE 731-20BR engines allow for better takeoff performance on hot days and at high airport elevations. Time to climb is also improved. Learjet 40 owners can upgrade to the XR through airframe and engine service bulletins.
The Learjet 40 is a shorter cabin version of the Learjet 45. Designed to replace the Learjet 31, the cabin is 4.5 feet longer than the 31 and has more head and shoulder room than the 31. The cabin has double-club seating, a galley and a full aft lavatory. The cockpit has a Honeywell Primus 1000 integrated avionics suite and the FADEC equipped Honeywell TFE 731-20 engine was developed in cooperation with Learjet for increased fuel economy and reduced operating and maintenance costs.
Deliveries of Learjet 40XR began in 2005.
