Irkut Corp. (Moscow, Russia) reports that its fourth MS-21-300 flight test aircraft made a nonstop flight from Irkutsk to the Ramenskoye airfield in Russia on March 17, continuing flight tests in pursuit of certification from the European Union Aviation Safety Agency (EASA, Cologne, Germany).
The aircraft, which was completed in December 2019, was piloted by first-class test pilot Oleg Mutovin and honored test pilot Roman Taskaev.
For this plane, specialists of the Irkutsk Aviation Plant, a branch of Irkut Corp. (part of the United Aircraft Corp.), installed a high-density, 211-passenger cabin configuration, though Irkut says the aircraft is currently equiped with 172 passenger seats, with control and measuring equipment as well as workplaces for test engineers located in the rear of the liner. Before carrying out certification tests of the passenger cabin, another 39 passenger seats will be mounted in place of the test equipment. Once the cabin is completed, tests for emergency exit for the aircraft will also be completed.
The MS-21 features the world’s largest infused, out-of-autoclave carbon fiber composite wings, which are manufactured by AeroComposit (Moscow, Russia).
