The Aermacchi M-290 TP RediGO is a turboprop-powered military basic trainer aircraft and liaison aircraft. It was originally manufactured by Valmet of Finland as the L-90 TP Redigo, a development of their earlier training aircraft for the Finnish Air Force. The L-90 was the last military aircraft designed and produced in Finland.[1]

The prototype, a modified L-80 first flew on February 12, 1985. A second prototype, powered by a Turbomeca TP319 turboprop, was destroyed in an accident in August 1988.[2] A total of 29 production aircraft plus the 2 prototypes were produced. Aermacchi purchased the manufacturing rights in 1996 but never returned the aircraft to production.[2]

The aircraft is of conventional configuration, with retractable tricycle gear and a low wing. The student and instructor sit side-by-side. As is typical with many military trainers, it can also carry light armament for weapons training, or potentially, for use in a close-support role. The Finnish Air Force only used the L-90 as a liaison aircraft.[1]
