Development of the L-410 was started during the mid-1960s by the Czechoslovak aircraft manufacturer Let Kunovice. The company had decided to launch the project with awareness that the Soviet airline Aeroflot was actively seeking a turboprop-powered replacement for the Antonov An-2 biplane, which was viewed as a potentially lucrative opportunity for a suitable aircraft. Preliminary studies performed by Let centred around a design referred to as the L-400. In addition to its use as an airliner, equal attention was paid towards its suitability for the role of a cargo aircraft.

Design

The Let L-410 Turbolet is an unpressurized all-metal high-wing commuter aircraft. It is characterised by its relatively low maintenance and operating costs, as well as its adaptable design, which includes special interchangeable configurations. All models are equipped with a retractable undercarriage. The L-410 UVP-E features two hydraulic circuits, one being the primary and the other intended for emergencies; the main electrical system operates with 28V DC. The de-icing system is leading edge pneumatic deicers and electrical heating of propellers, cockpit windshields and pitot-static system heads. The maximum take-off weight of the L-410 UVP-E is 6400 kg with the possibility of an increase to 6,600 kg (14,600 lb) for the E9 and E20 variants, possessing a maximum seating capacity of between 17 and 19 passengers. The L-410 UVP-E is equipped with Avia V 510 five-blade propellers..
