Learjet 31A

The Learjet 31A was announced in 1990 as a replacement of the Learjet 31.

The Learjet 31A features numerous updates to its avionics system, including a Bendix King Electronic Flight Information System 50, a dual KFC 3100 two-axis autopilot and flight director with yaw damper, and dual Bendix King VCS-40A com units. Unlike its predecessor, the 31A excels on short runways. It has increased takeoff and landing weights, as well as updated Honeywell TFE731-2-2B engines.

Production of the Learjet 31A ended in 2003 with over 200 jets being built. Prices for the aircraft average about $1.75M. Today, the model is mostly operated by private individuals and organizations, including NASA, United Arab Emirates, Vinci Aviation in Canada, and EN Securities of Iran.
