The first flight of import-substituted МС-21 aircraft, equipped entirely with Russian-made systems and assemblies, is expected in August this year, Russian Minister of Industry and Trade Anton Alikhanov said on Tuesday.

"MC-21 is already flying. So, we, along with colleagues from the UAC [United Aircraft Corporation], expect it to fly with all domestic systems in August. It is already operating with the PD-14 engine," the minister told the Federation Council, Russia's upper house of the parliament.

On June 26, Russian state corporation Rostec said that the MC-21 aircraft is in the final assembly shop and will soon enter the certification testing program. Testing has already begun in the Russian city of Zhukovsky in the Moscow Region.
