When Learjet 28 is a twin-engine business aircraft in low-wing design . The aircraft has a two-person cockpit and a cabin for up to ten passengers who are accommodated in the 1 + 1 seating arrangement. Typically, however, only seats for eight passengers were installed. The first flight of the Learjet 28 took place on August 24, 1977.
The Learjet 28 is based on the Learjet 25 , but received a completely new wing with winglets at the wing ends . The Learjet 29 is identical in construction, but is intended for a longer range. Commercial success failed to materialize because the engines were too loud and the fuel consumption was too high.
Of the Learjet 28 model, only five series machines were built, all of which were still in use in 1998. The Learjet 28 was replaced by the further developed Learjet 35 .
