The beginning of the exciting story of LET, dates back in 1936 when a branch of AVIA Letnany was built in Kunovice to service AVIA planes. During the WWII the company was forced to repair the Junkers W34 and Arado Ar 96b for Luftwaffe and after the war it worked on almost all the types of aeroplanes that were flying in Czechoslovakia.

At the beginning of the 50’s begun the construction of a new aeronautical company, which first produced the Russian JAK 11 and the AERO Ae 45 and AERO Ae 145.

In 1957 the company begun to develop the famous L 200 Morava and four years later the Z 37 Bumble Bee, which both brought a huge commercial success. For a period of time LET also produced a light training aircraft L 29.

 Over the years LET developed and produced a number of different gliders – Zlin Z 22, Z 124 Galanka, LF 109 Pioneer, Z 425 Sohaj. However the most popular gliders produced in LET are the famous Blaniks – L 13, L 23 and L 33.

During the 60s LET’s engineers developed a 19 seat commuter turboprop – the L410, of which more than 1,000 were produced since then. This popular aircraft has gone through a number of improvements and modernisations and the current types, the L 410 UVP-E20 and L 420 are EASA and FAA certified respectively.
 
In September 2005 the company was acquired by the Czech private group PAMCO and new company under the trade name Aircraft Industries was formed. In June 2008 the Russian industrial holding Ural Mining and Metallurgical Company (UGMK) acquired 51% of company shares.

L410 UVP-E20 / L420

The L410 UVP-E20 / L420 aircraft, which is the latest and most advanced successor of the famous L 410 aircraft series, is a well proven 19 seat turboprop commuter aircraft with outstanding technical parameters and operational reliability, easy handling and simple maintenance.

The L410 / L420 aircraft have been in production for over thirty years with an impressive safety record. Owners and users from different regions of Europe, Asia, Africa and America appreciate the aircraft's remarkable ”hot and high” performance and excellent STOL capability. They especially value its tough and durable structure and the ability to operate under extreme climatic conditions ranging from –50oC up to +50oC. Its durable airframe and unique design offer exceptional performance both in the torrid desert heat of Africa and Latin America as well as the most frigid regions of the world.

The L410 / L420 aircraft are equally "at home" operating in the Sahara desert or the Siberian tundra. The aircraft has proven consistent and reliable service in an exceptionally wide range of climate conditions, from dusty and dry African savannas to rainy areas of Latin America and from sea level to ”hot and high” mountainous destinations. The aircraft have been successfully operating in many countries and regions all around the world.

Product informational files

L13 AC Blaník

The two-seat all-metal L 13 AC Blanik is an improved version of the L 13 Blanik with excellent aerobatic characteristics. It has been designed for dual elementary and aerobatic glider training. The wing tip extensions improve its thermal and cross-country flight characteristics even further.

The aim of the L13AC Blanik is to promote instruction in aerobatics, including recoveries from unusual glider attitudes. The availability of this kind of glider, similar to the original Blanik, the most widely used trainer in the world, makes it possible for instructors to refresh their aerobatic skills, and to pass the confidence gained on to their students. The advent of the L13AC Blanik heralds more participation in glider aerobatics, and brings a boost to the sport of soaring.

The L 13 AC Blanik is manufactured according to BCAR requirements and is Type Certified in the Czech Republic and in the USA.

L23 Super Blaník

The world's most respected and popular two-seater training glider, the Blanik, is now available in a new improved version - the L 23 Super Blanik.

The new glider retains the the excellent flying and maintenance characteristics of the L 13 Blanik while visibility and handling are further refined.

Among many improvments are the new T-tail to minimize damage during land-outs, the swiveling tail wheel for easier ground handling and the new canopy enhancing visibility to the sides and back.

The L 23 Super Blanik is an all-metal two-seat self-supporting high-winged glider with an excellent flight characteristics and a service life of 10,000 flight hours. It has been approved for all stages of flight training from basic to advanced cross-country, aerobatic, stunt and instrument flying. It is manufactured according to the requirements of JAR 22 and is Type Certified in the USA, Canada, Brasil, Argentina, Germany, Great Britain, Spain, Austria, Sweden, Finland, Australia and other countries.

L33 Solo

The high ratings of the L 33 Solo all-metal single-seat glider are the result of sophisticated design development incorporating the latest in the soaring technology. The comfort and ease of flight and it's durability make it and obvious choice for all soaring enthusiasts. It is intended for an advance training and a performance soaring.

Pilots who received their initial dual instructions in the L 13 Blanik or L 23 Blanik will find the transition to the L 33 Solo absolutely natural.

The L 33 Solo is an all-metal single-seat cantilever mid-high wing sailplane with a semi-monocoque fuselage, fixed gear and cantilevar T-tail surfaces.
