The airplane departed Okha on a flight to Khabarovsk with intermediate stops in Nikolayevsk-on-Amur and Nijnetambovskoye. While descending to Nijnetambovskoye, the pilot encountered marginal weather conditions. Because the visibility was limited, he reduced his altitude to minimum. On final approach, at a height of 50 metres, the right wing failed and detached. The airplane nosed down and crashed in a pasture. All 16 occupants were killed.

The three engine airplane departed Moscow-Frunze Central Aerodrome in the morning on a local test flight, carrying nine passengers including one child and two crew members, one mechanic and one pilot. While cruising at an altitude of 900 metres, the mechanic informed the pilot about an oil leak below the right engine cowling. The pilot reduced his altitude and decided to divert to the Moscow-Oktyabrskoye Airfield. On final approach, at a height of 125 metres and at a speed of 120 km/h with both central and left engine at full power, the aircraft rolled to the right, stalled and crashed in a wooded area.

The airplane departed Irkutsk on a cargo flight to Bodaibo, carrying four passengers and a crew of three. While cruising some 40 km from Kirensk, weather conditions worsened and the visibility was poor due to heavy snow falls. The captain reduced his altitude, apparently to maintain a visual contact with the ground. At a height of about 20-30 metres, the airplane went out of control and crashed in the Lena River near the village of Kulebyakino, some 15 km southwest of Kirensk. Two passengers were injured while five other occupants were killed.

The aircraft departed Baku on a regular service to Tiflis (Tbilisi), carrying three passengers and two crew members. En route to Ganzhda and Yevlakh, the pilot encountered poor visibility due to foggy conditions. He reduced his altitude in an attempt to maintain a visual contact with the ground and followed the railway line. Approaching Göyçay, at a height below 30 metres, he realized he was facing trees so he initiated a sharp turn to the right when the aircraft impacted poplar trees. The right wing was partially torn off and the aircraft crashed. A female passenger was injured while four other occupants were killed.
