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 was of interest to 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.
- The ability to land on ordinary ground.
- Sufficient lifting capacity and comfort.
These are the characteristics that new liner... Photos 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 at the end of the 60s. The main purpose of the new air transport is to provide short air travel. The spaciousness of the cabin was supposed to be such that it could accommodate up to 20 people, and the aircraft was supposed to be serviced by airlines with a length of up to 650 km.
The Czechoslovak manufacturer successfully coped with the task set before him, new model The air vehicle 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 during scientific research.
The first model, named L-410, took to the skies at the end of the 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 cooperation 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 80s, the Soviet Union had acquired more than 100 L-410 aircraft models, and was not going to stop cooperation.

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 plan to increase the production of aircraft, improve the production process, and purchase new modern equipment.

What else do you need to know?
Summing up, we can say that the L-410 airliner is a reliable, unpretentious and maneuverable type of air vehicle, which has a reduced distance for both takeoff and landing. It is convenient to operate transport in conditions where take-off and landing of transport is difficult. Due to the sufficient safety factor, which was invested by the manufacturers, the aircraft can easily land and take off from unprepared and even from unpaved sites. The spacious cabin, equipped with large windows, has good sound insulation, the seats for passengers are located in the position 1+2.
This model is able to overcome about 1300 km, while carrying 19 passengers. and high-quality landing gear, manufactured according to a special method, allow the aircraft to land even on wet grassy ground. The liner showed itself well during operation in harsh climatic conditions, the excellent thrust characteristics of the engine allow the aircraft to be used both at high temperatures and at very low atmospheric pressure.
Excellent safety parameters allow you to safely transport passengers, deliver cargo intact and without damage. Throughout the history of its existence, the liner has been constantly modernized by the manufacturer; at present, the production of aircraft continues.
Together, the manufacturers plan in the coming years to create more advanced models, the engines of which have increased power, area luggage compartment will increase, the cockpit will be equipped with the latest equipment, including avionics.
In contact with
L-410 UVP-E20 is a versatile Czech-made twin-engine aircraft for local airlines, accommodating 19 passengers. It is intended for operation on unprepared unpaved, grassy, snowy areas, as well as on airfields with short runways (about 600-700 meters), which, in fact, makes it an off-road aircraft.
The first flight of the L-410 was made on April 16, 1969. The main customer of the aircraft was the Soviet Union. In addition, L-410 was also delivered to Bulgaria, Brazil, Hungary, East Germany, Libya, Poland. Despite the fact that the plant is located in the Czech Republic, it considers itself a part of the Russian aircraft industry: the foundations for this were laid during its development and with a long history of operation. As of 2012, more than 400 L-410 aircraft are in operation in the world.
Aircraft Industries production site in Kunovice, Czech Republic. Aircraft Industries, better known under the Let Kunovice brand, is located 300 km from Prague. The plant employs 920 people.
The enterprise manufactures an aircraft in a full production cycle - it has its own lines for surface treatment of materials, paint and varnish production, a machine shop, assembly shops, a design office and an airport.

The development of the L-410 aircraft began in 1966. The first sample rose into the air after 3 years. He carried the first passengers at the end of 1071. This flight was carried out by the Czechoslovakian company Slov Air. The following year, Czechoslovak developers transferred 5 vehicles to the USSR. Despite the good flight characteristics, work on improving the aircraft continued. So, already in 1973, the L-410M, equipped with an engine manufactured in Czechoslovakia, took to the air.
The next, more advanced modification of the L-410UVP appeared in 1979. It was distinguished by its large wings, vertical tail, and a longer fuselage. This modification became a production model.
But her improvement continued. In 1984, the L-410UVP-E variant appeared, which differed by more powerful engines... After 2 years, the aircraft, which received a certificate in the USSR, again received a different, powerful engine.
In the 90s, due to a decrease in demand, aircraft production fell to 2 - 5 per year, although before that they were produced by 50 per year. This continued until 2008, when 51% of the shares were purchased by the Ural Mining and Metallurgical Company. The production of aircraft increased and reached 11 aircraft in 2013. There was no further increase. Currently, most of the aircraft are in poor condition. But some of the L-410s continue to fly.
This small plane has enjoyed and still enjoys a certain popularity. It has been exploited and continues, albeit without its former intensity, to be operated in 40 countries. On local airlines, it has proven itself well even in Australia and Greenland.
In Russia, the L-410 is rarely used, since a significant part of local flights are not operated. These aircraft are available in the parks KrasAero, Orenburzhye and the airline PANH, located in Buryatia. Interest in the aircraft is shown in the Ministry of Transport and the Ministry of Industry and Trade, as well as in some regions with large territories with an undeveloped road network.
Although the developments used in the L-410 are far from new, a number of innovations introduced into it in subsequent years make it possible to operate the aircraft with an efficiency no less than existing modern models. Due to the use of new engines, its flight range has been significantly increased, and various cabin options allow it to be used not only as a passenger one. The advantage is the ability to use this aircraft at temperatures from minus 40 to plus 50 degrees. It should also be clarified that the L-410 can land on an unpaved runway.
The liner salon: comfortable and uncomfortable seats
Although the cabin of this small plane is designed for short-haul passengers, it offers all the comforts you can get. The seats are not much different from those installed in large airliners. Of course, sitting in them for a long time will be tiring, but this machine does not perform long-distance flights.
The chairs are arranged in 7 rows. But there is an option in which there are fewer rows. In this case, the number of seats is not 19, but only 17. In the first option the best places those in the first row are recognized. There are only 2 of them here: A and C. They are located on the left and right at the windows. For a tall passenger, seat B, located in the second row, is most comfortable. There is no chair in front of him, which makes it possible to quite comfortably place his legs.
During the flight, the noise of the working engines is clearly audible in the cabin. But it is not very loud. So passengers can talk to each other, as they do in any form of transport. There is no need to shout in the cabin.
A well-installed heating system ensures a comfortable temperature during the flight. So even in winter you can stay here without warm jackets, coats, fur coats. They fit easily into overhead racks. These shelves are enough for all passengers, but you cannot place something voluminous there.
It is also difficult to accommodate passengers with large bags. Going on a trip with more or less substantial luggage, you should place it in luggage compartment... There are two such compartments in the plane. Although they do not differ in large volumes, there is enough space for everyone.
Usually, when flying, many passengers simply do not know what to do so that the travel time passes unnoticed. In the cabin of this aircraft, passengers in the front rows are usually engaged in monitoring the work of the pilots. There is no blind door between the passenger compartment and the cockpit, so it is easy to observe what is happening in the cockpit.
Since flights are carried out at a low altitude, usually not exceeding 3 thousand meters, the pictures floating below are clearly visible through conveniently located windows. The advantage here is that you can look at the ground from any row. The view is not obscured by the wings above the windows.
Of course, we should also mention such convenience in this small plane as a toilet. It is located in the tail section. Of course, for those in the sixth (seat A) and seventh (seat B) rows as a passenger, such a neighborhood brings inconvenience. However, the toilet door opens not towards the aisle, but towards the front door, and there are not many passengers in the cabin.
The narrow aisle is also a special feature of the cabin. It is almost impossible for two to miss each other. But there is no movement towards each other on the plane. In addition, flight attendants with carts do not appear in the aisle, as is the case in large planes.
In the cabin layout for 19 passengers shown below. In the cabin layout for 19 passengers shown below, the numbering usually starts from the left as usual. The order of the seats is A, B, C. Number 5 indicates the toilet, number 11 - the luggage compartment.
Does the plane have a future
IN last years measures are being taken to revive small aviation in Russia. This also applies to the L-410 aircraft. Workshops for its production are mounted in the "Titanium Valley", where it was decided to place them UZGA. The commissioning of production facilities should take place in 2018. It is planned to produce aircraft not only for civil aviation, but also capable of performing a number of other tasks. This will also include the production of vehicles intended for the armed forces.
In all cases, the production will use the latest technology, which will make the aircraft safer and more comfortable. The passenger version of the L-410 will be used on intraregional lines, as well as for communication between cities of different regions with an insignificant passenger flow between them.

Conclusion
The available information suggests that the L-410 aircraft has not exhausted its possibilities for continued operation and further improvement. Its special advantage is the ability to take off and land where other airliners cannot. The ability to fly at high and low air temperatures allows it to be used in a wide variety of climatic conditions.
The number of passengers carried, although not as large as that of more large liners however, in most cases it is sufficient for passengers' requests, since the plane is usually used on intra-regional lines, or on routes between cities that are not so far apart from each other. When flying, passengers are in conditions that are almost equal to those of a large airliner. Further improvements will make it possible to make these conditions more comfortable.

Let L 410 "Turbolet" is a versatile nineteen-seat 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, unpaved, unprepared snow sites, as well as at airports with short lanes. Manufactured to date at the Czech plant Let. Other names: Turbolet, Let, L410, Let L410, conversational names - Elka, Cheburashka.
History of production and creation
The design of the aircraft began in 1966. For the first time, an experimental 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 at the end of 1971, the Czechoslovak aviation company "Slov Air" (Bratislava), 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 version 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 started, 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 there was a variant L410UVPE with more powerful TVDM601E. The first flight of such an aircraft took place on 12/30/1984. It has improved take-off and landing characteristics and a 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 was 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 civil flight schools for 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 percent of the shares of Let Kunovice (Aircraft Industries) were bought by the Russian company Ural 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), a TCAS system, and an autopilot. L410 UVPE20 is ARMAK type certified.
OJSC Ural Mining and Metallurgical Company in September 2013 acquired 49 percent of the shares of LetKunovice (Aircraft Industries). Thus, UMMC became the sole owner of Aircraft Indistries, increasing its shareholding to 100 percent.
