According to him, in the MC-21, the main part of the composite structures is located in the detachable part of the wing. Specialists have developed and manufactured two prototypes of the caisson up to 22 meters long and with a chord of up to 6.5 meters.

We are now making some changes to the design of the detachable part of the wing in order to realize the accumulated experience in the form of mass. We hope to remove several hundred kilograms from the wing. Well, a little from the tail and a little from the wing-fuselage fairings.
