russian civil aviation, which is suffering from Western sanctions, is already at the limit of its technical capabilities, the russian academy of sciences has said. soviet-made aircrafts, including all types of the AN family, have significant engine problems, which is why they crash from time to time. Since such aircrafts carry out 100 % of transportations in the Far East and the Far North, they are forced to be reduced to a minimum, as the risk of transportation increases to a maximum.
