The four engine aircraft departed Ulyanovsk on a cargo flight to Leninakan, carrying 5 passengers, 10 crew members and a load of 37,2 tons of construction materials and tools. The crew was cleared to descend to 3,300 meters then ATC transmitted the airport pressure being 637 mm Hg. The crew misunderstood this pressure value and the altimeters were mistakenly set at 736 mm Hg. This caused a gap of 1,100 meters and the aircraft continued the approach with a vertical speed of 10 meters per seconds.
