The Learjet 28 is an eight to ten seat (two crew and six to eight passengers), twin-engined, 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). Both were manufactured by Learjet, and were marketed under the Longhorn name.[1]
History
The first flight of the Learjet 28 took place on August 24, 1977. FAA certification was awarded to both models on July 29, 1979.[2]
The Learjet 28/29 was based on the LJ25, and received a completely new wing fitted with winglets which resulted in improved performance and fuel economy.[1] Both models were commercially unsuccessful due to engine noise and fuel consumption being too high.
Only five production LearJet 28s and four LearJet 29s were constructed before both types were replaced by the Learjet 35, with production ceasing in 1982.[1]
