The Learjet 70/75 is a light business jet airplane manufactured by the Learjet division of Canadian aircraft manufacturer Bombardier Aerospace.

Design[edit]

These models feature new avionics, winglets, and powerful engines that use less fuel.[4] The airframe is based upon the Learjet 40 and 45 models which it replaced.[5]The combination of aerodynamic improvements, which lowered the design's drag by 2%, and 200 lbs less weight in the nose section resulted in an increased range of 4%.[6] The canted winglet design was incorporated from the Bombardier Global 7500/8000.[7]

Development[edit]

The Learjet 75 received its type certificate from the FAA on 14 November 2013.[5] Deliveries began shortly thereafter.[8] This delay in certification caused order cancellations, and Bombardier's overall deliveries fell below expectations.[9] The 100th Learjet 75 was delivered in June 2017.[2]
