The Learjet 35 and 36 are extended, turbofan controlled advancements of the beginning Learjet models, the 23, 24 and 25.

The accessibility of the Garrett Airesearch Tfe731 turbofan in the late 1960s prompted an advancement of the Learjet 25 that was at first known as the 25b-GF (Garrett Fan). A testbed Learjet 25 with a Tfe731 on its left side flew in May 1971, while the conclusive Learjet 35 model first flew on August 22 1973.

Aside from turbofans, the 35 and more extend 36 vary from the prior Learjet 25 in having a 0.33m (1ft 1in) fuselage stretch and five windows (rather than four) on the right half of the fuselage. The Learjet 35 has seating for up to eight, however has less fuel than the more drawn out extend 36, which can just seat up to six, as both sorts have the same most extreme takeoff weight. The 35 and 36 were certificated in July 1974.

Upgrades to the two models prompted the 35a and 36a from 1976, with higher standard max takeoff weights. Both models stayed in creation until 1994.

Improvement of the 35 and 36 extent was made one stride further with the Learjet 31, which consolidates the 35/36's fuselage and powerplants with the more advanced wing of the 55 (now additionally on the 60) and delta blades under the tail. A 31 advancement air ship first flew in May 1987 and confirmation was recompensed in August 1988.

The enhanced 31a and 31a/ER are later creation shows, the 31a/ER being an augmented reach variation with a higher greatest takeoff weight and more fuel. Another inside with expanded headroom was presented in 1995. The 200th 31a was conveyed in October 2000.

Learjet turned into a Bombardier subsidiary in 1990.
