Russia's MC-21 Airliner Falls Short of Original Performance Claims

The MC-21, Russia's next-generation narrow-body airliner, is facing significant performance issues according to an internal assessment by Sberbank. The aircraft was designed to compete with Airbus and Boeing in the single-aisle market.

The original specifications for the MC-21 stated it could carry 175 passengers, have a range of 3,500 to 5,200 kilometers, and operate at altitudes of approximately 12,000 meters. However, the assessment found that the first production aircraft will have reduced performance compared to these specs.

The most significant changes are a decrease in commercial payload from 22,600 kilograms to 17,500 kilograms, and a reduction in range from 5,200 kilometers to 2,300-3,800 kilometers. Additionally, fuel consumption is expected to rise to 2,530-2,800 kilograms per hour, and the required takeoff distance will increase to between 2,125 and 2,410 meters.

The assessment also compared the MC-21 to Boeing's 737-800 and Airbus' A320-200. While the MC-21 has a distinct advantage in terms of passenger capacity, its range and fuel efficiency are comparable or worse than its competitors.
