In the morning, the pilot was supposed to take off from Mineralnye Vody to Zimovniki but the flight was cancelled due to poor weather conditions en route. At 1500LT, despite he did not received any permission, he took off with four people on a flight to Armavir. Approaching Kian at an altitude of 300 metres, he encountered thick fog. In limited visibility, he decided to return and initiated a turn to the left when, at a speed of 180 km/h, the airplane impacted the ground and crashed some three km south of the Kian Station. The airplane was destroyed and all five occupants were injured, three seriously. Few hours later, one of the passengers died from injuries sustained.
Probable cause:
The pilot's violation of the procedures in initiating a flight without permission and despite poor weather conditions.

Probable cause:
The accident was the consequence of the following factors:
- Violation of the published procedures on part of the pilot,
- The pilot modified his route,
- The decision of the pilot to return was taken too late.

Circumstances:
The pilot departed Mineralnye Vody Airport on a cargo flight to Rostov-on-Don. Shortly after takeoff, while climbing to a height of 25 metres, he initiated a turn to the right when the airplane stalled and crashed, bursting into flames. The pilot was killed.
Probable cause:
Investigations were unable to determine the exact cause of the accident. Nevertheless, it is believed that the pilot precipitated the takeoff procedure to allow another plane to depart immediately behind him. It was established that the airplane rolled for a distance of 620 metres only prior to rotation and that its speed during the first turn was insufficient, causing it to stall.

The pilot elected to return to Mineralnye Vody and initiated a turn. Shortly later, he lost his orientation and thinking he already passed the highest mountain, he initiated the descent when the airplane impacted the slope of a mountain part of the Mt Kazbek, about 7 km southeast of the summit (5,047 metres). The wreckage was found at an altitude of 4,000 metres and both crew members were killed.
Probable cause:
Controlled flight into terrain after the pilot got lost while cruising in reduced visibility due to foggy conditions and rain.

Circumstances:
The crew departed Kharkiv to ferry the airplane to its base in Tiflis with an intermediate stop in Mineralnye Vody. After takeoff from Mineralnye Vody Airport, the crew climbed to an altitude of 300-350 metres then continued to the southeast, following the railway track. About 20 minutes into the flight, weather conditions worsened and the visibility was poor due to fog. Rather than returning to Mineralnye Vody, the captain decided to continue and reduced his altitude. He continued vertical to the railway line, sometimes to its left sometimes to its right. Too low, the airplane struck the ground and crashed near the Apollonskaya Station in Novopavlovsk. One mechanic was seriously injured while both other occupants were killed.
Probable cause:
The accident was the consequence of the decision of the captain to continue the flight at low altitude in poor visibility due to fog rather than returning to Mineralnye Vody for a safe landing. It was determined that the information transmitted to the crew regarding the weather forecast were not relevant and were thus considered as a contributing factor.
