The Learjet 28 is an American eight-to-ten-seat (two crew and six to eight passengers), twin-engine, high-speed business jet, intended to be the successor to the Learjet 25. The Learjet 29 is identical except for the addition of a long-range fuel tank, resulting in the reduction of the capacity to six (two crew and four passengers).

The unsuccessful Gates Learjet 28 and 29 Longhorns are based on the 25 but introduced a new increased span wing fitted with winglets, which improved fuel efficiency and overall performance, particularly payload range and fuel economy.

The Learjet 28 is powered by two General Electric CJ610-8A turbojet engines. This is a single-shaft axial-flow turbojet, developed from the military J85. It has an 8-stage compressor section and 2-stage turbine.

The Lear 28 is very stable, has very low takeoff and landing speeds and subsequently can operate from runways of 3100¡¦ fully loaded at sea level on a standard day. This Lear 28 is the first production business aircraft with winglets.
