The MC-21 prototype in partially import-substituted appearance (board 0012) has been put under current. This is reported by AVIA.RU.
"This is an important stage of testing of the aircraft power supply system - the correctness of connection of switchgear to onboard (batteries) and ground power sources is checked," UAC notes.
The tests with the connection of the aircraft systems to the network will continue in the final assembly shop, and after their successful completion the aircraft will be transferred to the IAZ flight test station to prepare for the first flight in the new look.
