Circumstances:
The airplane departed Rostov-on-Don Airport at 1455LT and reached the assigned altitude of 8,400 meters at 1514LT. At this time, ATC instructed the crew to climb to 9,000 meters due to traffic ahead. The new altitude of 9,000 meters was reached two minutes later at 1516LT. While cruising in good weather conditions, the crew sent a brief message and mentioned the number '45' followed by a long pause. A second message was heard on the frequency with the number 'zero' then a third message with the pilot shouting the number '12'. Then the contact was definitely interrupted and the airplane entered a dive. During the descent, it reached the speed of 950 km/h and banked left to an angle of 75° before crashing in a cornfield located about 90 km from Dniepropetrovsk and 57 km from Krementchug. At impact, the airplane caused a huge crater and the accident was not survivable.
Probable cause:
The exact cause of the accident could not be determined with certainty. Nevertheless, the following facts were reported:
- There was no in-flight collision,
- There was no in-flight fire prior to impact,
- No military operations were in place in that area at the time of the accident,
- Both engines were turning at idle at impact.

Circumstances:
The crew started the approach to Yuzhno-Sakhalinsk by night and heavy rain falls. On short final, the captain realized he was well above the glide so he decided to increase the rate of descent. The airplane struck the runway surface nose first at a speed of 230 km/h and with a positive acceleration of 2,8 g. It bounced then landed a second time with an acceleration of 3,8 g. Upon impact, the nose gear was torn off, the engine number one detached and both wings were bent. Out of control, the airplane slid for several yards before coming to rest. All occupants escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
Wrong approach configuration on part of the pilot-in-command. Poor crew coordination and poor weather conditions were considered as contributing factors.

Few minutes later, the engine number four caught fire. The crew feathered its propeller when the oil pressure dropped and the propeller left the feather mode. Unable to maintain the prescribed altitude, the captain elected to make an emergency landing. The airplane belly landed in a field located 38 km north of Chișinău Airport and came to rest. The navigator, the radio operator, one flight attendant and 19 passengers were slightly injured while a passenger while killed. All other occupants escaped uninjured. The aircraft was destroyed.
Probable cause:

The aircraft collided with trees of the forest belt 2 km west of Satyshevo, crashed 170 metres further on, caught fire and burnt out. While a pilot was killed, the second occupant was injured.
Probable cause:
The captain was asleep at the time of the accident and the copilot was managing the mission alone. It was reported that the crew was performing all the spraying missions without any protection, while the pesticides used were highly toxic and dangerous. It was also noted that the altimeters were not connected at the time of the accident.

Circumstances:
The single engine airplane departed Akhty Airport at 0932LT on a return flight to Makhachkala with an intermediate stop in Derbent. While cruising at an altitude of 1,800 meters, the weather conditions deteriorated with more and more clouds. As the aircraft was flying in the direction of the Mt Gestinkil (2,785 meters high), the captain decided to climb to and altitude of 2,150 meters when the airplane struck the 45° slope of a mountain located in the region of Magaramkent, south part of Dagestan. As the copilot was slightly injured, he walked away to find help. On scene, rescuers were able to evacuate four injured people while two passengers died from their injuries.
Probable cause:
The accident was the consequence of a controlled flight into terrain caused by the fact that the crew continued under VFR mode in limited visibility due to clouds. Investigators reported that the airport authorities in Makhachkala and Akhty should not allow the crew to take off because of the deteriorating weather conditions, which remained a contributing factor.
