A dual TFE 731-3A-2B engine empowers the aircraft providing 3700 lbs of the thrust each.  The inspection interval is clocked at 4,200 hours. An adaptation of Longhorn 28 and 29 models, it has a grown wingspan apart from drag reducing winglets. Cabin space and the aerodynamic capabilities have been well looked after by the engineers. Emphasis has also been given to settle the in-flight sound level issues in the evolutionary stages. The fuel system has internalized wing tanks with 1424 pounds available in each wing. Gear system has the free fall ability newly introduced in the Lear jets. There are big pulleys in the control system of the crew for finer gearing.

Learjet 55 was a representation of the combo of Long horn model wings accompanied by the 30 series TFE731 turbofan engines with a newly built fuselage. The prototype 55 model was certified by FAA in March 1981 and it continued to be in production throughout 1985 and 125 aircrafts were built. The 55B model, a variant emerged with digital cockpit.
