After the success of the Let L.410 twin engine turboprop in the late 70s, Aeroflot requested a possible replacement for its An-24 aircraft. However, the collapse of the Soviet Union left the project vulnerable and attempts to 'Westernise' the plane were unsuccessful. Only eight aircraft were built (6 flying and 2 for structural tests). This is the fifth prototype, delivered to the Czech AF to support manufacturer's certification and test flights process and now on display at the Letecké Muzeum Kunovice.

OK-UZB was the third L-610 prototype and was primarily used for stress testing. This photo was taken at the museum's previous location at Olomouc. During the 2015-2016 period, the museum was forced to leave their Olomouc location. Eventually, they re-established themselves at a new location at Koněšín.

Let L-610M demonstrator

In total nine prototypes of the L-610M were produced; six for flight testing, two for static testing and one that was unfinished. X03 underwent trials at VZLÚ (Czech Aerospace Research Centre) but after cancellation of the L-610M program it was used for some L-610G tests. After the definitive end of the L-610, X03 went to the museum at Olomouc but is now on display at Letecké Muzeum Koněšín.

After the success of the Let L.410 twin engine turboprop in the late 70s, Aeroflot requested a possible replacement for its An-24 aircraft. This is the first prototype produced for the Let-610 program and is now preserved in a metal recycling company's yard in Staré Město.

However, the collapse of the Soviet Union left the project vulnerable and attempts to 'Westernise' the plane were unsuccessful. Only eight aircraft were built (6 flying and 2 for structural tests). This unfinished frame was intended for Czech AF but is now on display at the Letecké Muzeum Kunovice.

This plane was always thought to be OK-WZA c/n 910101. However, in August 2020 the dataplate was able to be checked and the airframe is now confirmed as c/n 920103. It was first noted in February 1994, still on the Let assembly line, and last seen there in July 1997. The plane never flew and was first noted at the museum in September 2013.

In 1993 the LET company demonstrator was taken on a promotional tour in the colors of the Czech air force. Now it is preserved in the Kunovice museum.

A lucky find for me - preserved in Stare Mesto, near Uherske Hradiste, is the first prototype of the unsuccessful L-610 airliner. It first flew on 28 December 1988.
