Introduced in 1981, the Learjet 55, also recognized as the Longhorn, stands as a compact twin-engine business jet meticulously developed and manufactured by Learjet. Unveiled as a key component of the 50 Series alongside the Learjet 54 and 56, the Learjet 55 was part of an ambitious initiative, although the latter models did not progress to production. The design ethos of the Learjet 50 Series embraced a low-wing cantilever monoplane configuration, featuring winglets and a distinctive T-tail. The aircraft’s smooth flying experience was facilitated by its retractable landing gear and potent Garrett TFE731-3A-2B engines. Despite this, subsequent variants were swiftly devised to elevate performance standards.
