EastRussia Bulletin: MC-21 serial release is delayed due to problems with composite materials
The implementation of a large civil aircraft project - the mass production of the medium-haul airliner MC-21 at the Irkutsk Aviation Plant has been delayed due to problems with the supply of composite materials. This was announced by the general director of the state corporation "Rostec" Sergey Chemezov.
Initially, MC-21 shipments were scheduled for the first quarter of 2020. The reason for the change was the refusal of foreign suppliers to sell composite materials to the Russian company Aerocomposite due to US sanctions. It produces composite panels for civil aircraft, and for the MC-21 it produces a composite wing, which is considered one of the main technical advantages of the new aircraft.
UAC previously reported on working with Russian companies to switch to domestic raw materials, in particular, with Rosatom and the All-Russian Research Institute of Aviation Materials. However, it will take considerable time to start producing Russian analogues. Thus, industry experts have previously estimated that in the event of abandonment of imported composites, the start of shipments of liners may be postponed for three years. In addition, such a decision may contribute to the cost of the project. Earlier, due to the unavailability of individual nodes, MC-21 certification was postponed - as of July 2020.
