The Let L-610 is a twin-engine passenger aircraft manufactured in the Czech Republic by the LET company. The machine was planned as a 40-seat turboprop machine for the Soviet Aeroflot in the mid-1980s , but was adapted for the western market after the fall of the Wall.

development

The L-610 is a further development of the also twin-engine Let L-410 , whereby the Let L-610 is equipped with western components. The original version L-610M flew for the first time on December 28, 1988. From 1991, several copies were delivered to Aeroflot. However, since this did not pay in western currencies , the delivery of further machines was canceled. There was a reorientation towards the western market.

The first flight of the modified version L-610G - also known as the Ayres 7000 through cooperation with the US company Ayres - took place on December 18, 1992. Instead of the original two 1358 kW three-shaft turboprop engines Walter / Motorlet M 602, it has two 1305 kW turboprop engines of the General Electric CT7 -9D type with four-blade propellers with a diameter of 3.35 m and Collins Pro Line II avionics and a Collins autopilot and weather radar system.

At the 1997 Aerosalon in Le Bourget , the L-610G OK-CZD was flown in front . Since there were no sales, the project was officially discontinued in 2006. The same fate befell the Walter M602 engines intended for the machine, of which only 34 were built.

In 2019 the Russian Ministry of Industry and Trade wanted to finance the further development of the Let L-610 - construction of the Let L-410 has been underway in Russia since 2016.
