Description
Development of the L-410 began in the mid-1960s by the Czech aircraft manufacturer Let Kunovice, who recognized an opportunity in Aeroflot's search for a turboprop-powered replacement for the Antonov An-2 biplane. Initial studies focused on the L-400 design, with attention given to both airliner and cargo aircraft roles. Following revisions, the L-410 Turbolet emerged, and the first prototype, XL-410, conducted its maiden flight on April 16, 1969. Due to delays in the development of a suitable Czech engine, the Walter M601, both the prototype and early production models were powered by Pratt & Whitney Canada PT6-27 engines and Hartzell three-blade propellers imported from North America.
The Let L-410 Turbolet is an unpressurized all-metal high-wing commuter aircraft. It is equipped with a retractable undercarriage, and the L-410 UVP-E model incorporates two hydraulic circuits, one primary and one for emergencies, with a 28V DC main electrical system. Its de-icing system uses leading-edge pneumatic deicers and electrical heating for propellers, cockpit windshields, and pitot-static system heads. The maximum take-off weight of the L-410 UVP-E is 6400 kg, potentially increased to 6,600 kg for the E9 and E20 variants, accommodating between 17 and 19 passengers, and utilizes Avia V 510 five-blade propellers. The design is adaptable featuring special interchangeable configurations.
Large numbers of L-410s were delivered to the Soviet Union; by 1985, 500 aircraft had reportedly been obtained by various operators within the USSR alone. Accordingly, the type has been heavily operated by various ex-Soviet states, in particular Russia. Furthermore, numerous L-410s have been sold to airlines across Asia, Africa, Central America, and South America. Forty aircraft are in use throughout Europe for commercial operations.
