Russian investigators have opened an inquiry after a Yakovlev Superjet 100 suffered a fatal accident near the city of Kolomna.
United Aircraft says the aircraft was performing a ferry flight on 12 July, without passengers on board.
Kolomna is around 100km southeast of Moscow.
Russia’s emergency situations ministry says the aircraft “crashed in a forest” with three crew members, none of whom survived.
The Interstate Aviation Committee identifies the twinjet as RA-89049, which was delivered new in 2015 to Gazpromavia, the aviation division of energy firm Gazprom.
It says it has formed an commission to investigate the accident.
The Superjet 100 is equipped with PowerJet SaM146 engines.
United Aircraft says the developer and manufacturer will provide “all necessary assistance” to the inquiry.
According to the federal Investigative Committee, the aircraft was bound for Moscow Vnukovo airport having taken off “after repairs” from another facility – apparently the Lukhovitsy plant.
It says the crash occurred near the village of Apraksino, and the organisation has opened a routine probe to establish whether there was any criminal element to the accident.
