Learjet 31

The Learjet 31 is an American-built, twin-engined, high-speed business jet manufactured by Learjet, a subsidiary of Bombardier Aerospace, as the successor to the Learjet 29. It carries eight passengers and two crew. The first flight of the LJ31 took place on 11 May 1987, and the Learjet 31A variant, introduced in October 1990, brought a higher cruising speed, a digital avionics system with EFIS from AlliedSignal and a changed instrument panel. The first 31A entered service on 15 August 1991, the 200th was delivered in October 2000 and the last, serial number 31A-242, on 1 October 2003. A 31ER variant with increased range was also produced. Power comes from two Garrett TFE731 turbofans, and the type combines the fuselage and engines of the model 35/36 with the longhorn wing of the 28, 29 and 55.
