Introduced in 1990, the Learjet 31 and 31A stand as small, twin-engined, high-speed business jets developed and manufactured by Learjet. The Learjet 31 was meticulously optimized for high-altitude operations, achieving reliable performance by merging the Longhorn wing design with powerful engines derived from the Learjet 35/36 model, mounted on the rear fuselage of the same model. However, this configuration resulted in a small, cramped cabin with limited space for luggage, leading to the development of the Learjet 31A. Beyond slight design modifications, the most notable difference from the previous model lies in the enhanced avionics systems installed in the cockpit.
Red Box is delighted to present an extensive range of ground power equipment tailored for the Learjet 31A aircraft. This includes tugs, ground power units, start power units and more, meticulously designed to meet the specific requirements of the Learjet 31A.
Among our offerings are the 747C tug, and the RBSC150 continuous power unit—ideal for diagnostic work, pre-flight checks, or continuous powering of equipment during operations without depleting the onboard aircraft batteries. Additionally, the Twin RB75A is available for starting the aircraft, aiding in the prevention of hot starts. Our TC3000 range also provides a convenient combination of start and continuous power in one unit for the Learjet 31A.
