The Learjet 60 is a mid-size cabin, medium-range business jet aircraft manufactured by Bombardier Aerospace in Wichita, Kansas, USA. Powered by two Pratt & Whitney Canada 305A engines, it has a range (with 4 passengers and 2 crew) of 2,405 nautical miles (4,454 km) with NBAA 100 nmi (190 km) reserves, ISA. In July 2012 Bombardier Aerospace announced a temporary "production pause" of the latest variant Learjet 60XR to begin in the fourth quarter of 2012.
The Learjet 60 is an improved version of the Learjet 55, with a longer fuselage and more powerful turbofan engines. It first flew on 10 October 1990 and received FAA certification in January 1993.
The modifications that converted the Learjet Model 55 into a Model 60 resulted from an aerodynamics improvement program and a need to increase the capacity of the Learjet product line. Several of these modifications were a first for Learjet, including an all-new inboard wing cuff added to the inboard sections of the “Longhorn” wing and an all-new wing-to-body fairing. By increasing the wing chord and the leading edge droop, the wing cuff improved handling during approach and landing, while the wing-to-body fairing reduced the interference drag between the wing and the fuselage. Since the engines were new for this aircraft, a new engine pylon had to be designed.
The lines of the cockpit have not changed but the fuselage was lengthened. In addition, the blend between the fuselage and the empennage was all new. While it appears as if area ruling was the intention of the blending, the blend design was really driven by attaching the original Learjet Model 35 empennage onto the larger Learjet Model 60 fuselage.
