Russia's United Aircraft has appointed senior vice-president Oleg Demchenko as chief of Irkut, succeeding Alexey Fedorov who had been at the helm since February 2011.
United Aircraft says its board has accepted a management proposal to free Fedorov from presidential duties upon his request.
Demchenko has been "instrumental" in developing both the Irkut MS-21 and Yakovlev Yak-130 aircraft, it adds.
His appointment should allow Irkut to "preserve continuity in managing these projects" and "secure the company's high efficiency", it states.
United Aircraft has not specified whether, or in which capacity, Fedorov would continue to work with the firm, whose board has also appointed Vnesheconombank governor Vladimir Dmitriev as chairman for another year.
