Russian Irkut MC-21 has successfully completed second flight-test on 12 May 2018. The Aircraft MC0003, numbered 73053, took off from its facility at Irkutsk, reached an altitude of 3,000m and speeds of up to 215kt in a flight which lasted for 1h 7min.
Irkut said the testing was successful, after tested for basic stability, undercarriage retraction, and wing configuration during flight.
The aircraft powered by Pratt & Whitney PW1400G geared turbofan engines is expected receive Russian certification in mid-2019 and EASA certification in mid-2020.
Most significant advantage of MC21 is its composite wings, whereas its immediate competitors, both Boeing 737 Max and Airbus A320 use metal wings. The other competitor, Bombardier uses an in-autoclave resin transfer infusion process to manufacture C Series wings.
According to Irkut and parent company United Aircraft (UAC), MC-21’s list price of $91 million is almost 15-percent lower than the current cost price of Airbus A320.
