"The Interstate Aviation Committee's commission for the investigation of the crash of the An-148-100B RA-61704 informs you that the deciphering of the data of the onboard data flight recorder was completed in the IAC laboratory and preliminary analysis of the information was carried out," the IAC said.
It said a "special situation" with the An-148 plane began some 2 minutes 30 seconds after takeoff at an altitude of about 1,300 meters and a speed of 465-470 kilometers per hour, adding that wrong data on flight speed, apparently due to icing, could have led to the crash.
