Development of the L-410 was started in the 1960s by the Czechoslovakian aircraft manufacturer Let Kunovice. The Soviet airline "Aeroflot" was looking for a turbine-powered replacement for the Antonov An-2 aircraft, initiating the design development by Let. After preliminary studies of an aircraft called the L-400, a new version was introduced called the L-410 Turbolet. The first prototype, designated XL-410, flew on April 16, 1969. Because of delays in the development of a suitable Czech engine (Walter M 601), the prototype and first production version were powered by Pratt & Whitney Canada PT6A-27 engines. After M601 development was completed, the PT-6 engine was replaced by Walter M 601 engines coupled with Avia V508 three-blade propellers and the next variant was introduced, the L 410M. A further version for Aeroflot was the L 410 UVP. This has improved performance in take-off and landing due to increased wing and tail area - STOL. However, due to an increased empty weight and a shift in the center of gravity, the aircraft had a decreased seating capacity: 15 passengers. The L 410 UVP-E (the most common variant of the L 410) has increased maximum take-off weight to 6400 kg, M 601E engines with increased power, new five-blade propellers designated V 510 and the provision for wing tip tanks to increase fuel quantity. First flight was made in 1984, and production started in 1986. The L-410 UVP-E9 and UVP-E20 are versions which vary from each other only by minor changes arising from various certification regulations. The last L 410 family member is the L 420 which uses the new Walter engine variant, the M 601F. The L 410 UVP-E aircraft is an unpressurized all-metal high-wing commuter aircraft, powered by 2 reverse-flow Walter M 601 turboprop engines (2x560 kW take-off power) and Avia V 510 five-blade propellers. It is equipped with a retractable undercarriage. The aircraft uses two hydraulic circuits: main and emergency.
