Why do they show photos of that model aircraft... I thought the new version didn't have bracing wires nor separate struts to stress the lower and upper wing...
They show this photo:
When this aircraft is supposed to look like this:

I suspect its down to maintenance issues. Carbon fibre and all that are very difficult to repair.
The old, rugged stuff is far easier to maintain. Esp when you are 1000s of miles from anywhere and anyone with technical knowledge of composite materials repair.
And that was the beauty of the An-2.
An-2 and its replacement are pragmatic and practical. If you want something pretty and poncey - buy a Cessa Citation or whatever.

Well, a perfect solution does not exist... it is always a compromise... composites have several advantages, but also many limitations in comparison to metals. Especially if they want to build not expensive and easy to maintain aircrafts that need to operate in remote areas...
The other problem for this aircraft is that no russian engine exists. The current engine is an american turboprop with 1000 hp (about 750kW). The Let-410 will have two russian engines VK-800 with 800/850 hp. Two other turboshafts in development (from which a turboprop could be derived) are in the 550-650hp range and around 1600hp. In addition, there is probably the need for a 4000 hp engine. It is possible that a russian engine with 1000hp will emerge in the future, but now it is not the priority...

Composites often delaminate when they fail so normally you replace rather than repair unless it is a puncture damage situation.
Perhaps what they need are more durable composites that are better suited to cold temperatures or a wider temperature range... and they certainly need new engines...
They need to make the design more modular and easier to repair and support in the field...

Czech aircraft again?
What is the obsession with them?
The Czechs are part of the EU, it's a hostile bloc. In case of economic warfare or serious tensions, all their companies will have to abide by whatever sanctions regimes. No more joint-production, no more spare parts.
I can understand buying Airbuses and Boeings, where Russia is not able to offer competition for now, and Russia also supplies them titanium parts and R&D to make co-operation a 2-way street; but surely the An-2 developments offer an alternative to the Let aircraft.

It is a totally different class of aircraft, and basically a smaller an-140.
Furthermore the czech manufacturer is owned by a Russian company, and the Let-610 design will be used only as a starting point. From what I understood this will result in a Russian owned design (with a new designation) that will be built in Russia almost entirely from Russian components (engines included).

TsAGI completed tests of the model of the Russian-Chinese widebody
In Zhukovsky, the next stage of wind tunnel experiments was completed under the program of the Russian-Chinese wide-body long-range CR929 aircraft, which is jointly created by PJSC United Aircraft Corporation and China Civil Aircraft Corporation. This was reported by the press service of FSUE TsAGI.
“For the first time in our practice, it became possible to compare the test results of the same model in transonic aerodynamic installations of several countries,” said Anton Gorbushin, head of the laboratory of the research complex for aerodynamics and flight dynamics of aircraft TsAGI.

Azimut Airlines with SSJ100 aircraft breaks even
https://sdelanounas.ru/blogs/128541/
https://sdelanounas.ru/blogs/128541/
Azimut Airlines, which completed its first regular commercial flight in September 2017, reached operational break-even in the 3rd quarter of 2019, i.e., in almost 2 years.
Azimut is the only airline in Russia with a fleet of only Superjet 100 aircraft. This year, Azimut received three Superjets and now its fleet has 11 aircraft of this type, all delivered under contracts with GTLK (State Transport Leasing Company) . By 2023, according to management, it is planned to increase the fleet to 16 SSJ100 aircraft. The airline is based at the airports of Rostov-on-Don and Krasnodar. In 2018, 700 thousand people were transported, the forecast for 2019 is 1.2 million passengers.
Co-owner of the air carrier Vitaly Vantsev:
- “Pleased and Sukhoi Superjet. Despite the criticism we heard about this aircraft, we have 99.8% regularity today. Regularity is best in the country only one airline - “Victory” on foreign equipment, on the Boeing 737. ”
- “I am glad that the business plan and life correspond to each other. In the III quarter of this year, the airline first broke even - earned operating profit "
According to Vantsev, airline flights show good occupancy at 85%. “The project is very difficult. We work entirely on the Russian product, 80% of Azimut Airlines flights are regional, bypassing Moscow ”

When they developed laminates and composite materials they generally focus on light weight and strength... their problems often include durability and high cost, and clearly the ability to be used in extreme temperatures.
Perhaps they need to design a new version with a more modular design where components most likely to fail or need replacing can be easily and cheaply replaced, but they need long term experience... so my suggestion would be to look at all the potential customers operating deep inside the Far East who currently use An-2s who like the product and want to keep using them, and work with them by leasing them a composite at reasonable prices and then working together with them through the next 5 years of use... what works and what needs to be fixed... and the wear and tear model of normal and abnormal use so weak points can be identified and the design revised to allow weak points to be small and cheap and easily replaceable in the field... at the same time get a record of the real environment these aircraft work in... not what the manual says... what they actually do in the field, and also work on making the composite materials more temperature independent, and of course cheaper and easier to make.
The An-2 has been in use since it was introduced in the late 1940s, so taking an extra five years to get this right should not be a problem... and if they can get a new composite design that is actually better than the old model in every way... including new Russian engines and propellers... there would be a big market in Russia and potentially Canada and the world... Africa will appreciate a low cost aircraft too... this could make flying to isolated places much more cost effective and open them up to development and growth...

The fourth MC-21 is in the air
According to PJSC United Aircraft Corporation (UAC), on December 25, 2019, the first flight of the fourth MS-21-300 aircraft intended for flight tests took place at the airport of Irkutsk Aviation Plant, a branch of PJSC Irkut Corporation (part of UAC).
The flight duration was 1 hour 40 minutes, it took place at an altitude of about 3000 meters at a speed of about 500 km/h.
The plane was piloted by a crew of test pilots, Heroes of Russia Roman Taskaev and Oleg Mutovin. According to the crew’s report, the mission was completed in full, the flight went normally.
During the construction of the machine, the results of flight and ground tests of the first experimental MC-21-300 aircraft were taken into account.
On the bmpd side, we recall that the first first prototype of the promising medium-range passenger aircraft MS-21-300 (serial number 21001 / МС.0001, registration number 73051, tail number "001") made its first flight in Irkutsk on May 28, 2017.
The second prototype of the MC-21-300 aircraft (serial number 21003 / МС.0003, registration number 73053, flight number "002") made its first flight there on May 12, 2018.
The third prototype of the MC-21-300 aircraft (serial number 21004 / МС.0004, registration number 73054) made its first flight there on March 16, 2019.
