The Let L 410 "Turbolet" is a versatile nineteen-seater twin-engine aircraft for regional airlines. The aircraft with reduced take-off and landing properties (UVP in the name L410 UVPE20 means the Russian abbreviation "Shortened take-off and landing") was developed by the Let design bureau of the plant. It was intended for operation on grassy, \u200b\u200bunpaved, unprepared snow sites, as well as at airports with short lanes. Manufactured to date at the Czech factory Let. Other names: Turbolet, Let, L410, Let L410, conversational names - Elka, Cheburashka.
History of production and creation
Aircraft design began in 1966. For the first time, a prototype aircraft equipped with a Pratt & Whitney PT6A27 (2x715hp) turbine engine passed flight tests on 04/16/1969. Regular use of L410A aircraft was opened by the first Czechoslovakian aviation company Slov Air (Bratislava) at the end of 1971, which served the local aviation lines - by the beginning of 1974 it had acquired twelve aircraft. A total of 31 aircraft were built. 5 aircraft (number 72010306 and number 720201) L410A with PT6A27 engines, built under the name L410AS by 1972, were transferred to the Soviet Union in 1973. The aircraft received registration Soviet numbers USSR67251 - USSR67255. The first of them was brought to the airfield by Frantisek Svinka, a Czech test pilot. The airfield people immediately called the pretty plane "Cheburashka".
In 1973, flight tests of the L410M aircraft, equipped with the Czech theater of operations Walter M601A, began. The L410M became the second production variation of the Turbolet. In total, by the end of 1978, one hundred L410M / MU aircraft were received for the Ministry of Civil Aviation of the Soviet Union.
In 1979, the production of an improved modification L410UVP began, which became the main production model. This aircraft differed from the previous versions by a longer fuselage, large vertical tail and wing sizes, the use of spoilers and a HPT Walter M601V (2x730hp). This aircraft passed the certification program in the USSR and was taken into use by Aeroflot. Further development was the L410UVPE variant with more powerful TVDM601E. The first flight of such an aircraft took place on 12/30/1984. It has improved takeoff and landing characteristics and reduced noise level in the cockpit. In 1986 he was certified in the Soviet Union. A modification of the L420 with powerful TVDM601 ° F (2x778hp), a larger take-off weight (6.8t) and improved flight properties has been developed (flight tests of the aircraft started in 1993).
By the beginning of 1992, 750 L410 aircraft remained in the Soviet Union.
It is used in military and civilian flight schools for the preliminary training of future pilots of military transport and long-range aviation.
After the collapse of the Soviet Union and CMEA in the 1990s, the demand for L410 aircraft fell, and the rate of their production decreased by more than ten times (from 50 aircraft per year to two to five). The situation has improved significantly since 2008, when 51% of the shares of Let Kunovice (Aircraft Industries) were bought by the Russian company Uralskaya Mining and Metallurgical Company. The production rate in 2010-2012 was eight to ten aircraft per year. It is planned to increase the annual production rate to 16-18 aircraft.
In 2013, a modification of the L410 UVPE20 was produced, equipped with analog or digital avionics (optional), TCAS system, and autopilot. The L410 UVPE20 is ARMAK type certified.
OJSC Ural Mining and Metallurgical Company in September 2013 acquired a 49 percent stake in LetKunovice (Aircraft Industries). Thus, UMMC became the sole owner of Aircraft Indistries, increasing its shareholding to 100 percent.
The aerodynamic configuration is a twin-engine turboprop high-wing aircraft with a single-fin tail.

The Let L-410 Turbolet is a Czech (Czechoslovak) passenger and transport aircraft designed for regional transportation. It can carry up to 19 passengers or 1.7 tons of cargo. Among the advantages of the model are reliable design, safety, temperature resistance (-50 ... +50 ° C), the ability to land on a short unpaved runway. The first prototype took off on April 16, 1969, and more than 1200 units have been produced since production began in 1971. The main buyers of these machines are Russia and the CIS countries. They are also used in Asia, Africa, Europe and South America.
Historical reference
The development of the L-410 aircraft began in the mid-1960s by the Czechoslovak aircraft building plant Let Kunovice according to the drawings of the Taganrog design bureau Beriev. The Soviet airline Aeroflot was looking for a replacement for the outdated Antonov An-2 turboprop models. The new aircraft were supposed to communicate with regional settlements located in various climatic zones - from the tundra to the subtropics. The most important conditions were compactness (with a capacity of up to 20 passengers), high efficiency, short acceleration, and the ability to land on unpaved runways. The turboprop scheme was perfect for these purposes.
The production was entrusted to Let as a member of the Council for Mutual Economic Assistance of the socialist bloc. The XL-410 prototype carried out a test flight on April 16, 1969 under the control of factory pilots Vladimir Vlk and Frantisek Svinka. The first examples were equipped with Pratt Whitney Canada PT6-A27 engines and three-blade Hamilton Standard propellers.
When the development of the Czechoslovak-made Walter M601 engines was completed, the PT6 power plants were replaced by the M601A (later the M601B), and the three-bladed Avia V508 propeller appeared on the aircraft. A prototype with new equipment was prepared in 1973, and in 1974 it made its first flight. The model received the marking L-410M. In 1975, supplies began to the USSR.
Description
Turbolet belongs to the class of non-pressurized all-metal aircraft, for this reason, the flight altitude is limited to 4200 km above sea level. The aircraft is capable of climbing above 6,000 km, but in this case the use of oxygen masks is required.
Two 3/5 blade turboprop engines are highly efficient and have sufficient thrust for short takeoffs. However, the speed had to be sacrificed - 300-335 km / h in older versions and 417 km / h in the new NG version. However, this is not critical for regional flights.
The passenger compartment is compact, 5-7 rows. There are 2 chairs to the right of the aisle, and one to the left. The seats are comfortable enough. In the back there is a toilet with a washbasin and a mini-wardrobe. There are VIP versions with a sofa (berth), soft armchairs, a coffee table, a TV, a kitchen-bar and a refrigerator.
Flight safety is ensured by a double hydraulic circuit (main and emergency) and an automatic reduction system (availability depends on the modification) in the event of a breakdown of one of the engines. The main electrical system operates at 28 VDC. Anti-icing is provided by front pneumatic defrosters and electrically heated propellers, cockpit windscreens and air pressure taps.
Specifications
The parameters of L-410 aircraft of various modifications are presented in the table.
Since 2014, a special version of the Let-410 E20 with skis on the chassis has been developed. In April 2017, this modification was successfully tested at a Russian polar station 100 kilometers from the North Pole, deployed on drifting ice.
This is a modification with a shortened take-off and landing length, the takeoff run is only 456 m. It differs from the classic version:
- extended fuselage;
- improved braking system;
- increased wing area;
- reduced to 15 seats capacity;
- fixed stabilizer (vertical tail).
The wings are equipped with spoilers and an automatic emergency control system (ABC). They help to control the rate of descent (lift) and are triggered if one of the engines fails.
The first aircraft were powered by M601B engines. Later, their own modification of the M601D power plants was developed for them. The model entered production in 1976.
Let UVP-E
The E series is the most common UVP range. She possesses:
- increased maximum takeoff weight;
- stronger engines Walter M601E;
- five-bladed V510 propellers.
The most productive version is the L-410 UVP E20. It allows you to transport 1.8 tons of cargo or 19 passengers. It can be equipped with a pair of Walter M601E (2 × 750 hp) or GE H80-200 (2 × 800 hp) engines. External fuel tanks can be installed at the end of the wing. The first flight took place in 1984, serial production started a year later.
Let L-410 NG series
In March 2018, the serial production of an improved version of the UVP E-20 started. She received the index L-410NG. The twin-engine turboprop transport / passenger aircraft manufactured by the Czech company Aircraft Industrie received an elongated fuselage, which made it possible to increase the volume of the luggage compartment.
The model is equipped with:
- a more powerful and quieter GE H85-200 propulsion system with Avia-725 propellers;
- modern cabin from Garmin;
- wings of a new design with integrated fuel tanks.
The new engine complies with strict European regulations for noise and environmental performance. The carrying capacity was increased by 400 kg, the speed was increased to 417 km / h, and the flight range was a record 2570 km for this model. The operating altitude remained the same - 4200 m, the maximum ceiling - 6096 m. The aircraft can operate continuously for up to 10 hours.

Production
The L-410 Turbolet turned out to be extremely successful. So much so that it is still being produced in various variations. Compact dimensions, short acceleration, loyal requirements for runways, the ability to transport both passengers and cargo, high efficiency, low operating costs allowed the technology to gain a foothold in the market of Eastern Europe and especially Russia for a long time.
The L-410 is manufactured by Aircraft Industries (formerly Let Kunovice) from the Czech city of Kunovice. Today the enterprise belongs to the Russian state corporation Ural Mining and Metallurgical Company. According to reports, from 1971 to 2016, about 1200 units were sold. There are about 350 aircraft of this brand in operation in the world today, both in civilian and military versions. Approximately 50 boards are used in Europe.
Several years ago, a project was launched to localize the production of Turbolet in Russia. On July 7, 2015, specialists from the Ural Civil Aviation Plant in Yekaterinburg assembled the first aircraft from Czech vehicle kits. In the future, it is planned to increase the share of spare parts, assemblies and mechanisms manufactured by domestic manufacturers.
Operators
Turbolet is operated by the Air Force and civilian airlines in more than two dozen countries in Europe, Central and South America, South Asia, North and Central Africa. Among commercial air carriers, the following companies have the largest fleet of Let L-410 aircraft (according to data for 2006-2016):
- "Universal-Avia" - 13 units (Ukraine);
- Atlantic Airlines de Honduras - 10 (Honduras);

As we wrote earlier, in our country a program is being carried out to localize the regional 2-engine aircraft L-410 (see our material ), we also reported on work on the domestic VK-800S engine (see. ). The Ministry of Industry and Trade of the Russian Federation has published new data on the state of work on aircraft of regional aviation.
According to the Deputy Minister of Industry Oleg Bocharov, now work on transferring the production of L-410 to Russia is in the following state:
100% Russian avionics are ready for the aircraft.In terms of quality, it is seriously higher than what Thales offers, and for the first time for KRET (Concern "Radioelectronic Technologies") a Russian product is cheaper (!) Than its imported counterpart, despite the small serial production. For the first time in a modern civil aircraft construction project, the industry has reached the level of economically justified import substitution, and this is a real positive from our "defense industry".
The new VK-800S engine was first tested on the L-410 last summer.Now the first experimental series of these power units with a Stupa propeller is being assembled.
In November 2018, the first aircraft produced at UZGA (Ural Civil Aviation Plant) was presented to the President of the country, the production of which is localized in Russia. The new assembly shop with an area of \u200b\u200b12,500 square meters allows us to say that the serial production of the L-410 is technically ensured up to the level of 20 aircraft per year.
« We are already certified float landing gear for L-410 (see). The aircraft took off / landing even at a shorter distance. We are undoubtedly moving towards ensuring that our residents in the regions receive a comfortable product, so that in any weather conditions, on any lanes, to receive a reliable service. At the same time, work is underway on certification ski chassis, - notes the Deputy Minister of Industry of Russia - it will be a completely Russian aircraft, provided with a full range of opportunities for timely after-sales service. Of course, ski flyer, float flyer. Of course, there is a desire to go further, so that he took off from skis, sat on a float, took off from a float, sat on a landing gear, and sat on skis from a landing gear. This is probably still in the future. So far, we can only talk about homogeneity. But the plane very quickly "changes shoes", it is done practically in the field. There were requirements, especially in the Far East, related to the fact that the certificate has restrictions on the runway, and that there are better imported counterparts. Nothing like this - we received the confirmation of the certificate, carried out all tests... 550 meters are sufficient conditions for the aircraft to operate without degrading its operational characteristics.
Also, work was carried out on additions to the certificate, which should be validated in the near future. We understand that it can fly over open water areas. In general, it will be a universal aircraft for regional companies, which will have the ability to transform the cabin: transport version, ambulance, passenger. We would like to make a very flexible offer so that airlines can provide a wide range of aviation services. A special set of tools has also been developed that can drastically reduce the scheduled maintenance of equipment.
Czech colleagues * in cooperation will have the "tin work" on the airframe. We believe that there is no need to localize it in Russia. And the entire highly intelligent production part is localized in Russia ", -notes Oleg Bocharov.
While creation is in progress new production of 64-seat Il-114-300 aircraft (The Ministry of Industry and Trade has already pledged funding for the assembly of the first 3 such aircraft in 2021, work on the TV7-117ST engines is nearing completion), it was also decided to take into work the ready-made documentation for the development of the L-410 - aircraft L-610... This is a 40-seat machine with 2 turboprop engines, which was created in the last years of the USSR in Czechoslovakia by order of Aeroflot. Subsequently, the project was abandoned, and after the plant was bought out by the Russian owner, the documentation was revised taking into account the requirements of the 2010s. L-610, also localized in Russia, will be produced at the Ural Civil Aviation Plant.
In the photo: one of the experienced L-610, 1990s

Thus, in our country, over the next 5-7 years, a line of regional 2-engine aircraft of various capacities will be created, independent of Western suppliers of equipment and engines: these are localized 19-seat L-410 and 40-seat L-610 and the updated 64 -seater Il-114-300.
* note that the plant for the production of L-410 in the Czech Republic is wholly owned by the Russian UMMC
The first L-410 aircraft was created in the 60s of the last century by Czechoslovak manufacturers by order of the USSR. It was the Soviet Union that was the main customer of this type of air transport, however, this model interested companies from other countries:
- Poland and Lithuania;
- Bulgaria and Hungary;
- Brazil.
After all, the advantages of the aircraft could be assessed even with the naked eye:
- Lightness and maneuverability.
- Ability to land on ordinary ground.
- Sufficient lifting capacity and comfort.
These are the characteristics of the new liner. A photo of the L-410 aircraft cabin can be viewed on our Internet resource.
Airplane L-410
The first model of the L-410 aircraft, as noted earlier, was created in the late 60s. The main goal of the new air transport is to provide short air travel. The spaciousness of the cabin had to be such that it could accommodate up to 20 people, and the aircraft had to be serviced by airlines with a length of up to 650 km.
The Czechoslovak manufacturer successfully coped with the task set before him, the new model of the aircraft turned out to be not only reliable and unpretentious, but also multi-purpose, which, in fact, was required by the customer.
Having received a new type of air transport at their disposal, the liner began to be used for:
- passenger and freight traffic;
- for the transportation of correspondence;
- for transportation of patients;
- for various scientific research.
The new model of air transport was appreciated not only for maneuverability, but also for the ability to take off and land in places where there was no runway, which was extremely important when transporting patients or conducting scientific research.
The first model, called the L-410, took to the skies in the late 60s, however, as the manufacturers noticed, the air transport engine was insufficiently powerful. Therefore, it was decided to make several changes to the production process, in particular, they affected the engine. So, by the mid-70s, the modernized L-410 with a more powerful engine were launched into series, 5 of which were transferred to the Soviet Union.
The main customer was satisfied with his order and continued to cooperate with the manufacturer, and the first air transport was bought by the then most famous company Aeroflot. You can see a photo of the Let L-410 aircraft on the website. By the early 1980s, the Soviet Union had acquired more than 100 L-410 aircraft models, and was not going to stop cooperation.
The cabin of the aircraft L-410
A variety of aircraft models L-410
The Czechoslovak manufacturer did not stop at his achievements, constantly creating more and more improved models of liners. The production of the following models was established:
- L 410 UVP;
- L 410 A;
- L 410 AS;
- L 410 M.
The L 410 UVP model was also developed at the request of the Soviet customer; the aircraft differed from its counterparts in the increased wing length and fuselage, as well as the tail, made in vertical design. This modernization allowed the liner to take off and land at an even shorter distance, which was the main requirement of the customer.
The demand for air transport from the Czechoslovak manufacturer, of course, subsided after the collapse of the USSR, but the Ural Mining and Metallurgical Company helped to save the situation, which 8 years ago bought more than 50% of the shares from the first manufacturer. Currently, the partners are planning to increase the production of aircraft, improve the production process, and purchase new modern equipment.
