"Material evidence will be collected to expose the cause of the air crash," it said.
The An-28 jetliner crashed in flying from Petropavlovsk-Kamchatsky to Palana on Wednesday. Ten people, including two crewmembers, a four-year-old girl and a citizen of Belarus born in 1977, died. Four passengers were injured, among them a 13-year-old teenager.
