The newest commercial jet developed in Russia, the MC-21 (MS-21) is undergoing a long process of replacing components originally supplied by the West.
Currently, Yakovlev, the manufacturer that took over the project within the UAC (United Aircraft Corporation) conglomerate, is undergoing certification flights of the MC-21-310 variant, which was equipped with PD-14 engines instead of the PW1400G, which was supplied by Pratt & Whitney.
The newest stage reached, according to Rostec, a Russian state-owned technology company, is the delivery of avionics systems developed in the country.
The work was carried out by Concern Radioelectronic Technologies, which recently sent the first set of avionics, including control panels for aircraft systems and lighting equipment.
The project was supported by the Ulyanovsk Instrument Design Bureau, which developed the MC-21 cockpit software. According to Rostec, the equipment is capable of controlling hydraulic, fuel, inertial, anti-icing systems, fire protection systems, air conditioning, speed measurement, among others.
“Even before the start of SVO [Special Military Operation, as the Russians call the invasion of Ukraine], the MC-21 project became the target of Western sanctions. Despite the unprecedented pressure and the need for large-scale import substitution, Rostec companies are coping with the assigned tasks,” said Rostec Executive Director Oleg Yevtushenko.
He further explained that soil tests and equipment installation are being carried out on the MC-21.
The new jet is expected to replace Western aircraft such as the Airbus A320 and the Boeing 737.
