Orders and deliveries of the business jet
Jet Republic ordered 25 Learjet 60XR jets with 85 as optional in June 2008. The contract value of the firm orders was $340m.
Bombardier, however, cancelled the order in August 2009 as Jet Republic went into bankruptcy. The total value of the contract would have been increased to $1.5bn had all optional orders been confirmed.
Bombardier delivered the first Mexican Learjet 60XR to an undisclosed customer in March 2010. China also received its first Learjet 60XR in the same month.
Design of the Learjet 60XR
Bombardier Aerospace designed the Learjet 60XR by modifying the existing Learjet 60. The sleek and aerodynamic design of Learjet 60XR decreases the drag in flight.
The fuselage was elongated by 1.09m compared to that of the Learjet 55.
A number of new features such as upgraded avionics, modern cabin design, advance avionics, three disc steel wheel brakes, increased baggage area, a larger galley, a spacious lavatory, an electronic power ports and advance entertainment systems were incorporated in the Learjet 60XR.
