The engine has warmed up: flight tests of the import-substituting SSJ-100 New will take place in early 2025, by Vladimir Gavrilov for Izvestia. 12.27.2024.
How many airliners are planned to be produced from 2026 and will there be enough of them for aircraft fleets?
In early 2025, flight tests of two SSJ-100 New aircraft with Russian PD-8 engines will be conducted, the United Aircraft Corporation (UAC) told Izvestia. In parallel, work is underway to deploy serial production of the SSJ-100. About 20 aircraft are in various stages of readiness. The import-substituting airliner is essentially a new aircraft that should gradually replace the Franco-Russian aircraft with SaM146 engines. After 2026, the corporation will reach production volumes of up to 30 aircraft per year, but by that time the workload of Russian airlines' fleets will be critical due to the growing demand for transportation and the withdrawal of foreign aircraft, experts say.
New aircraft with PD-8 engine
Two import-substituting SSJ-100 New aircraft are prepared for testing in 2025. Currently, passenger cabin options are being tested on the airliners and equipment is being tested.
We expect to receive the PD-8 engines in early 2025, after which the aircraft will be transferred to the plant's flight test station in Komsomolsk-on-Amur to prepare for flight tests , — UAC (part of the Rostec state corporation) told Izvestia. After the installation and testing of the power plants, the fully import-substituted airliners with domestic equipment on board will take to the air.
Until now, only aircraft with Franco-Russian SaM146 engines have flown. Even the first import-substituted version of the SSJ-100, used since June 2024 for flight tests of aviation equipment, is armed with foreign engines . In the Russian-French PowerJet SaM146, the entire "hot part" (gas generator, high-pressure compressor, combustion chambers and turbines) was manufactured by the French Snecma. After the introduction of sanctions, problems with their maintenance arose, so a course was taken to completely update the aircraft. Import-substituted SSJ-100 New with PD-8 engines will conduct about 200 test flights during the year, UAC noted.
Replacing the SaM146 with the PD-8 is not economically feasible - it would require a similar cycle of certification tests, which is expensive and time-consuming , the United Engine Corporation (UEC, part of Rostec) told Izvestia. Therefore, the SSJ-100 New aircraft was created for the PD-8 and domestic equipment .
In fact, this is a deep modernization of the aircraft, which will allow placing about 40 import-substituting systems and units. The new equipment differs in dimensions, the airframe design has been redesigned, the production process, maintenance and repair of the aircraft have been simplified, the UAC said.
There are 46 main suppliers for the SSJ-100 New, and the production cooperation includes 20 thousand enterprises . For example, the avionics complex and auxiliary power unit are made in Moscow , fuel equipment and hydraulic elements in St. Petersburg, and engines in Rybinsk , the aviation corporation said.
The experience of many years of operation of the airliner was taken into account. As previously reported to Izvestia by the Ministry of Industry and Trade, based on the results of the recommendations of the IAC, the aircraft developer was recommended to modify the chassis design. After testing, the design solutions will be implemented on the SSJ-100 New . A service bulletin will also be issued for the modification of the flying fleet. The main landing gear doors are made in Kazan, the landing gear itself is made in Samara, and the tires are made in Barnaul.
In parallel, UAC is working to launch serial production of the SSJ-100 New. The final assembly shops of the Yakovlev production center in Komsomolsk-on-Amur are being reconstructed, where a straight-through line will be organized . A new hangar for the flight test station for two aircraft has already been put into operation. At the moment, about 20 aircraft are in various stages of readiness . According to the Ministry of Industry and Trade, in 2025, UEC will deliver six PD-8 engines, and in 2026 - 44, which can be used to equip up to 22 SSJ-100 New.
In the future, the enterprise plans to reach a rhythmic production rate of about 30 aircraft per year, UAC said.
What will replace foreign airliners?
With the introduction of the modernized SSJ-100 New, the old airliners with SaM146 engines will continue to be operated . As reported by UEC, the corporation's facilities have organized service maintenance of engines to maintain their airworthiness. A range of consumables that were previously supplied from abroad has been developed and is being produced, including a fuel filter, spark plug and other parts , the company added.
“Import substitution of fuel filters is extremely important, as there have been problems with them in recent years ,” Andrey Patrakov, founder of the RunAvia flight safety service, told Izvestia.
The fact is that filters for SaM146 were manufactured abroad and were not supplied after the sanctions were imposed. Imports are difficult due to the extremely limited number of manufacturers. Therefore, old filters were simply cleaned and reinstalled on the aircraft, which created risks of their incorrect operation , the aviation expert noted.
According to UAC, in less than three years the number of SSJ-100 components serviced in Russia has increased fivefold and today amounts to 311 items . Domestic analogues have been mastered for 214 components. Nine alternative components have been developed, and by 2026 their number will grow to 59.
There will be a great need for airliners in the near future. There are clearly not enough foreign planes to satisfy the growing demand for transportation , aviation expert and editor-in-chief of the Avia.ru portal Roman Gusarov told Izvestia.
Currently, the seat occupancy rate has exceeded 90%, and on some flights it has approached 96%. In 2026, the aircraft shortage will put significant pressure on the market. Therefore, the sooner the deliveries of new aircraft begin , the better, the expert notes.
“We also need to think about maintaining the airworthiness of foreign aircraft,” Andrey Patrakov noted. “This will help extend the airworthiness of the Airbus and Boeing fleet.”
For now, problems with spare parts and components are being resolved, despite the total pressure from unfriendly countries. However, the existing supply channels are not eternal , the expert noted.
— We need to prepare domestic industry to produce components for foreign airliners, even if this requires colossal investments , — Andrey Patrakov believes. — For example, to adapt the domestic PD-14 engine, as well as avionics to the Airbus A320, we need to spend up to half the cost of developing a new aircraft.
According to him, in the current reality such expenses may become justified, since it will be faster than domestic aircraft appear, the expert summed up.
