The large winglets — noticeably taller and more sharply canted than those of later Learjet 30-series aircraft — are the key recognition feature. The Model 55's T-tail further distinguishes it from the 28/29. Both are wider than the original narrow Learjets.

History

By the mid-1970s the original Learjet wing's efficiency was limiting range. Learjet developed large Whitcomb-style winglets, first flown on the Model 28 in 1977. The winglets allowed transatlantic range on the Model 55 mid-size jet, which entered service in 1981 with a stand-up cabin and T-tail.

Variants

The Model 28 and 29 are narrow-body Longhorns; the Model 55 is a wider, mid-size development with a stand-up cabin. The Model 55C added winglets to an already winglet-designed airframe.

Where you'll see it

Operated globally by corporate and charter customers as a medium-range business jet; the Model 55 found particular favour for transatlantic missions.
