Circumstances:
Following an uneventful flight from Krasnodar, the crew started the approach to Omsk Airport in a reduced visibility due to the night and rain falls. The aircraft landed at a speed of 270 km/h and about one second later, the captain noticed the presence of vehicles on the runway. He initiated a turn to the right when the left wing struck the vehicles. Upon impact, all three vehicles were destroyed and the four people on board were killed instantly. Out of control, the airplane turned to the left, veered off runway and came to rest upside down, broken in two, bursting into flames. Four crew members and one passenger survived while all 174 other occupants were killed.
Probable cause:
It was determined that the person in charge of the runway maintenance allowed a team of three vehicles to enter the runway for maintenance and then fell asleep. Thus, he failed to inform ATC about the presence of ground vehicles on the runway and the Air Traffic Controller based in the Airport Tower was unable to see the vehicles due to poor visibility caused by night and rain falls. As ATC was not aware of the presence of ground vehicles, he was unable to inform the crew prior to landing. Also, it was reported that the vehicles dispatched on the runway were not equipped with rotating flashing beacons and radios that would allow their personnel to listen the tower frequency.

While cruising in good weather conditions at an altitude of 2,700 meters and at a speed of 300 km/h, control was lost. The airplane nosed down and entered a dive. Elements from the stabilisers and from the wing tips detached during the descent and the aircraft crashed in a nose-down attitude of 15-20° and at a speed of 330 km/h in a field located 3 km southwest of Nashchekino, some 9 km off course. The airplane was totally destroyed upon impact and all six occupants have been killed. The aircraft was on its way from Tbilisi to Myachkovo with an intermediate stop in Krasnodar, carrying 20 empty gas bottle and few boxes containing metal parts for a total weight of 1,792 kg.
Probable cause:
The exact cause of the accident could not be determined with certainty. However, it was reported that the aircraft CofG was too far front and that the cargo was not properly secured. Both engines were running at impact and there was no fire prior to final impact. It is possible that the loss of control was also the result of atmospheric turbulences or an unexpected disconnection of the automatic pilot system.

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.

While cruising at an altitude of 900 meters off Tuapse, the aircraft went into clouds when it was struck by lightning. Out of control, it dove into the Black Sea and crashed about two km off the Soviet Ministry of Internal Affairs' rest house located in Tuapse. The aircraft disintegrated on impact and sank by a depth of 55 meters. Some debris were found 3 to 4 weeks later, nobody survived.
Probable cause:
It was determined that the aircraft was struck by lightning while flying in an area with thunderstorm activity. Lightning struck the left rear fuel tank and an explosion occurred while contacting fuel vapors. For unknown reason, the crew has not been informed about the presence of thunderstorm and lightning in the region of Tuapse.

Circumstances:
The crew was supposed to convoy the airplane (delivery flight) from Pyatigorsk to Krasnodar with an intermediate stop in Vorochilovsk (now Stavropol). Prior to departure from Vorochilovsk, the crew estimated the weather conditions as suitable and took off at 1540LT for Krasnodar. Few minutes after takeoff, weather conditions deteriorated and the visibility was too low. Despite the situation, the pilot decided to continue in clouds when he lost control of the airplane that crashed in a wooded area located south of the city. The pilot was killed and the flight engineer was injured.
Probable cause:
Failure of the pilot to continue the flight in below minima weather conditions and his failure to continue the flight rather than to return to the departure airport. Poor flight preparation was a contributing factor.
