When will the domestic MS-21 aircraft start carrying passengers?

The medium-range domestically produced MS-21-300 aircraft truly possesses high technical specifications. According to its designers, it was intended to be the most advanced aircraft in the world in its class. However, its serial production, which would then enable mass passenger transport, has been repeatedly delayed.
The MS-21's main advantage over its classmates is its aerodynamic properties, which, among other things, should allow for a significant reduction in fuel consumption with comparable engine power, payload, and speed.
It seemed the engineers had thought of everything. But a lot went wrong. Initially, serial production of the MC-21 was planned for 2016, and the first aircraft were supposed to be delivered to Russian carriers just two years later. However, in 2018, foreign companies refused to supply composite materials for the Russian airliner. As a result, the start of serial production was postponed until 2020.
The problem was resolved domestically. In 2021, the MS-21 took to the skies with a wing made entirely of domestic composites. However, the Russian "black wing" proved heavier than originally planned. Furthermore, the following year, it suddenly became clear that more than 80 systems, previously planned to be purchased abroad, needed to be replaced. The main problem was replacing the American PW1400G engine with the Russian PD-14.
It was crucial that the domestic engine and other key components not affect the aircraft's technical characteristics. It turned out that achieving this within the design specifications, including aerodynamics, interior space for passenger comfort, external dimensions, weight, and so on, was unrealistic.
These challenges are being addressed through engineering solutions, including compromises. Some of the airliner's original design characteristics have had to be sacrificed, but overall, the work, albeit with significant delays, is proceeding successfully.
On April 29, 2025, Rostec announced the first test flight of the MS-21 with new Russian systems. The tests included domestically produced avionics, electrical power supply systems, air conditioning, and other components. This flight marked the start of factory development testing.
On October 28, 2025, the Russian Ministry of Industry and Trade announced the first test flight of an import-substituting aircraft equipped with PD-14 engines. In November of this year, the second import-substituting MS-21-310 with domestically developed systems completed a nonstop flight from Irkutsk to Zhukovsky (Moscow Region) for certification testing. Production of serial aircraft is already underway at the Irkutsk plant. aviation The aircraft is being developed at the Rostec United Aircraft Corporation plant. Certification of the aircraft is expected to be completed next year, allowing for its delivery to airlines.
Experts note that, despite the reduction in some of the aircraft's technical characteristics (primarily, range and weight) and delays in serial production, the MS-21 will be the world's first aircraft built almost entirely from components produced within a single country.
According to the Russian government's comprehensive civil aviation development program, airlines will receive 270 MC-21-310 aircraft by the end of 2030. Aeroflot Group will receive 108 aircraft by this date. An additional 92 aircraft will be delivered to the airline by 2032. Other customers include Smartavia (45 aircraft), Aurora (15), and IrAero (7). Rostec stated that the MC-21 is primarily intended for the domestic market, but the state corporation is also counting on interest from foreign buyers.
