The aircraft departed Ust-Kut Airport on a cargo flight to Mirny, carrying a load of 18 tons of cement. Few minutes after takeoff, the crew was informed that a landing at Mirny Airport was impossible due to technical problems and the captain decided, without referring to his operations, to divert to Lensk Airport where the weather conditions were considered as poor. At that time, the sky was overcast with clouds down to 600 meters, an horizontal visibility of 2,500 meters with rain and snow. The flight was continued at an altitude of 8,000 meters then the crew was cleared to descent to 3,000 meters and to start the approach to Lensk. On final, the pilot-in-command failed to realize his altitude was insufficient when the airplane struck tall trees (20 meters high) in a flat attitude, continued the descent and crashed 420 meters further in a wooded area. The wreckage was found 15,6 km short of runway threshold. The aircraft was totally destroyed and all six crew members were killed.

On the leg from Novosibirsk to Yakutsk, the hydraulic pressure on engine number 2 dropped. The captain decided to divert to Krasnoyarsk Airport for an emergency landing. The approach was completed in snow falls and during the last segment, the four engine airplane was too low and struck the ground 200 meters short of runway threshold then crashed and burned. There were no casualties but the aircraft was destroyed.

On a flight from Zyryanka to Seymchan in support of the 121st geodetic expedition, the crew encountered below-minima weather conditions due to low clouds. The crew failed to return and deviated from the prescribed flight path by 25 km and descended in clouds over mountainous terrain. In such conditions, the aircraft crashed at a height of some 1,200 metres into the steep slope of Mount Khapchagai (1,554 metres high) located 61 km northwest of Seymchan. One of the 2 pilots and 4 of the 6 passengers were killed and all survivors were seriously injured. The wreckage and the survivors were found a day later, on 23SEP68.

On final approach to Mirny Airport, the crew lowered the undercarriage when the left main gear detached and fell away. The captain decided to attempt an emergency landing in a wasteland. After touchdown, the aircraft banked left, causing the left wing tip to struck the ground and to be torn off, as well as a part of the engine number one. The aircraft slid for several yards before coming to rest. While all occupants escaped uninjured, the aircraft was written off.

While approaching Psebai on a flight from Krasnodar, the crew encountered below-minima weather conditions (low visibility due to rain falls) and decided to return but it was too late. At a height of 1,050 metres, the airplane struck tree tops and crashed on the wooded slope of the Skalisty khrebet mountain range (1,314 metres high) located 7.5 km northeast of Psebai. The wreckage was found on August 31 only. All 14 occupants have been killed.

The aircraft was engaged in a crop-spraying flight for the sovkhoz (state farm) "Novo-Zolotovski" in the Semikarakorsk district of the Rostov region with one pilot and a local guide on board. While at a height of 20-25 metres, the pilot probably got distracted by the passenger and lost control of the airplane that descended and struck the ground, caught fire and burnt out. While the passenger was killed, the pilot was injured.

During a crop-spraying flight for the kolkhoz (collective farm) "Pobeda" in the Ust'-Labinsk district of the Krasnodar region, the pilot-in-command lost control of the airplane that crashed in flames in an open field located near Tenginskaya. Both crew members were killed and the airplane was destroyed by a post crash fire.

On a crop-spraying flight from Nikitskoye (Kurkino district of the Tula region) for the sovkhoz (state farm) "Pobeda" when probably the control of the flaps and ailerons failed immediately after take-off. Pilot dropped the load and managed to keep control for some time, but after flying 8 km, aircraft banked to the left, turned upside down and crashed in a field of the sovkhoz (state farm) "Polibino" located 1.5 km northwest of Maryinka (Dankov district of the Lipetsk region). The aircraft caught fire and burnt out and the pilot, sole on board, was killed.

The crew was completing a local training flight at Moscow-Domodedovo Airport. On final approach, he failed to realize his altitude was too low when the airplane struck power cables and crashed few hundred yards short of runway. The aircraft was destroyed and all five crew members were killed.

During the takeoff roll at Volgograd Airport, after a course of 1,000 meters and while at a speed of 260 km/h, the captain attempted to rotate and pulled the control column. In the same time, he mistakenly pushed the spoiler switch for a period of three seconds. After rotation, the aircraft climbed to a height of 10-15 meters and flew for a distance of about 400 meters then banked left and struck the ground. Upon impact, the left wing was torn off and the airplane crashed in a grassy area and came to rest, broken in three. The wreckage was found 83 meters to the left of the runway and 1,640 meters from the runway threshold. 44 people were evacuated safely while four others were seriously injured, among them the copilot, the board mechanic and the board agent. The radio navigator was killed.
