Circumstances:
The crew departed Moscow-Vnukovo Airport at 0520LT on a flight to Tbilisi with an intermediate stop scheduled at Rostov-on-Don. Due to the deterioration of the weather conditions and the presence of a storm between Krasnodar and Sukhumi, the crew decided to modify his route and obtained the permission from ATC to divert to Krasnodar. The crew and the passengers waited for few hours at Krasnodar Airport and the aircraft took off at 1507LT bound for Tbilisi. While cruising under VFR at an altitude of 2,400 meters, the crew encountered poor weather conditions with thunderstorm activity, heavy rain falls, turbulence, hail and lightning. Within few minutes, the aircraft was hit by lightning and suffered heavy turbulence so went out of control and entered a dive. At an altitude of 300 meters, the crew elected to regain control but high g forces exceeded the design of the wings that were torn off. Out of control, the airplane crashed in flames in a wooded and hilly terrain located near the village of Grigorishi, about 15 km northeast of Zugdidi. The aircraft was totally destroyed and all 18 occupants were killed.
Probable cause:
Loss of control caused by poor weather conditions consisting of thunderstorm activity with heavy rain falls, hail, turbulence and lightning.

Few minutes later, while cruising vertical of the Caucasus Mountain Range, the crew encountered poor weather conditions when the aircraft hit the slope of a mountain. SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the 23 occupants was found. The wreckage was found by walkers in an isolated and mountainous area of north Georgia on June 20, 1947.
Probable cause:
Wrong decision on part of the crew to change the itinerary, against all published procedures and navigational rules.

Circumstances:
The airplane departed Tbilisi Airport at 1233LT on a flight to Krasnodar with intermediate stops in Ordzonikidze (Vladikavkaz) and Mineralnye Vody. After departure, the crew climbed to an altitude of 2,500 metres then continued over the Caucasian Mountain Range. As weather conditions deteriorated, the pilot climbed to an altitude of 4,000 metres and realized it would not be possible to pass over the mountains so he decided to fly to the east, direction Baku. Shortly later, while flying at an altitude of 4,000 metres, the airplane caught fire in flight and crashed on the slope of Mt Ninikas-Tsikhe, bursting into flames. The airplane was destroyed and all three crew members were killed.
Probable cause:
The exact cause of the in-flight fire could not be determined with certainty.

Circumstances:
At 0800LT, the crew departed Tbilisi Airport on a short flight to the nearest airport of Vaziani where seven skydivers were picked up for a local exercise. During the takeoff roll at Vaziani Airport, the airplane veered to the left and the pilot aborted. A second attempt to takeoff was also abandoned few minutes later for the same reasons. As the crew thought that the mudguard was rubbing the left wheel, they proceeded with a slight modification of the position of the mudguard. On the third attempt to takeoff, the airplane lifted off then climbed to a height of 2-3 metres when it turned 90° to the left, causing the left wheel to touch the ground. The airplane rolled on a distance of 88 metres then the right wheel struck the ground as well. The airplane continued on a distance of nine metres then crashed. The airplane was totally destroyed and two paratroopers were killed. The other occupants were injured.
Probable cause:
It was determined that the loss of control after takeoff was the consequence of the failure of the right rudder control cable.
The following contributing factors were identified:
- The person in charge of the maintenance of the airplane was asked on October 20 to proceed with the change of both rudder control cables. The mechanic failed to comply with this order, did not proceed with any change and reported to his superiors that he changed the cables, which was not the case,
- The superior failed to check the work from his mechanic prior to release the airplane,
- The crew failed to inspect the airplane prior to takeoff and did not comply with published procedures,
- The pilot continued the takeoff procedure with an apparently defective airplane and failed to reduce the engine power when the airplane turned left after liftoff.
