The Let L-200 Morava light twin-engine transport was preceded in production at the Let factory by the license-built Aero Ae 45. In 1955 the newly created design team led by Ladislav Smrcek of the Czechoslovak State Aircraft Factory decided to proceed with a proprietary design for a more modern twin with seating capacity of five and powered by a pair of then new 210 hp Avia M 337 engines, but as they were not yet available, the prototype made do with the less powerful Walter Minor 6-III engines of 160 hp each. While maintaining similar characteristics of western twin engine aircraft of the time, updated features of the Morava included twin tails, standard thermal wing de-icing equipment and inverted inline engines. The first production L-200A took to the skies in February 1960. In all, 367 L-200s were built by 1964, including 3 prototypes and 197 L-200D (eight L-200A and the L-200A prototype were converted to L-200D as well). 5 aircraft were manufactured from parts by Libis in Yugoslavia.
