Aircraft Industries, a.s., operating as Let, n.p., is a Czech (formerly Czechoslovak) civil aircraft manufacturer. Its most successful design has been the L-410 Turbolet, of which more than 1000 units have been built. Its head office is in Kunovice, Uherské Hradiště District.
Building of an aircraft factory in Kunovice started in 1936, as a part of the Škoda Works industrial concern. Before and during World War II the unfinished plant served only as a repair works. After the end of the war the factory was nationalized and in 1950-53 a new plant was built. In 1957-1967 it was named SPP (Strojírny první pětiletky - "Works of the First Five-year Plan"), and in 1967 it returned to the name LET. The works produced under licence were the Soviet trainers Yakovlev Yak-11 (under a designation C-11) and the Aero Ae 45 and Aero Ae 145 utility aircraft.
In 1957 the company began to develop the L-200 Morava light utility aircraft and four years later the Z-37 Cmelak agricultural aircraft, which were both a commercial success. For a period of time LET also produced a jet training aircraft the L-29.
Over the years LET developed and produced gliders–Zlín Z 22, Z 124 Galánka, LF 109 Pioneer, Z 425 Šohaj. However the most popular gliders produced by LET are the Blaníks–L-13 Blaník, L-23 Super Blaník and L-33 Solo.
During the 1960s LET’s engineers developed a 19 seat commuter turboprop – the L-410 Turbolet, of which more than 1100 were produced. This popular aircraft went through a number of improvements and modernisations and the latest types, the L 410 UVP-E20 and L 420 are EASA and FAA certified respectively. 
The Let L-610 was produced in a prototype form and displayed at the Paris Airshow. Production was cancelled due to lack of funding. There were 8 protopypes made in the factory.

The all-metal Blaník sailplane was produced in the largest quantities of any sailplane, with over 3000 manufactured since the first rolled off the production line in 1958. In 2005 it was still in production as the L23 Super Blaník variant.
