Russian airframer Irkut has formally submitted an application for type certification of the MC-21 twinjet.

Federal air transport authority Rosaviatsia has confirmed the application from Irkut president Oleg Demchenko.

It has appointed a representative to co-operate on the certification process for the Pratt & Whitney PW1400G-powered aircraft, which was rolled out in June.

Rosaviatsia says it will take into account a request to recognise previous certification foundations on which the design of the aircraft has been based.
