Circumstances:
On approach to Krasnovodsk Airport by night, the crew encountered marginal weather conditions and at an approximate altitude of 300 meters while on a distance of 5 km from the airfield, the aircraft's speed dropped from 260 km/h to 200 km/h with a rate of descent of 2,5 meters per second. The crew elected to correct this configuration but the aircraft continued to descend until it struck, at a speed of 150 km/h, a rocky cliff situated on the shore of the Caspian Sea, some 159 meters above sea level and located about 4,700 meters short of runway threshold. Upon impact, the right engine and the right wing were torn off, the aircraft bounced and then crashed in flames few dozen meters further. Two crew members and 21 passengers were killed while 15 other occupants were injured.
Probable cause:
It was determined that the aircraft was caught by orographic turbulence on final approach whose speed was about 30 meters per second (108 km/h). This caused the aircraft to lose altitude and speed and any correction from the flying crew was unsuccessful. The following contributing factors were reported:
- Lack of knowledge on part of the meteorologist about the characteristics of such specific climate phenomenon,
- The absence of a system able to detect such phenomenon,
- The crew inexperience in such flight conditions.

Circumstances:
The airplane was engaged in a special mission on behalf of the Voyekova Geophysical Observatory, carrying a crew of five and six passengers, among them three employees of the observatory. Following a successfully mission consisting of thunderstorm observation, the crew was approaching Bagdarin when he encountered poor weather conditions with low clouds and heavy rain falls. While descending to an altitude of 600 meters in clouds, the airplane struck tree tops, stalled and crashed in flames in a wooded area located on the slope of a mountain (827 meters high), about 28 km from the Bagdarin Airport. The aircraft was totally destroyed and all 11 occupants have been killed.
Probable cause:
Poor approach planning on part of the crew who failed to follow the approved procedures and adopted a wrong approach configuration, causing the aircraft to descend to an unsafe altitude over mountainous area and in poor weather conditions. The lack of visibility due to clouds and rain was considered as a contributing factor as well as a poor ATC assistance.

Circumstances:
During a crop spraying flight for the kolkhoz (collective farm) "Mayak" at Chirsova (Comrat district of Moldova), the crew allowed two unauthorized passengers to board. In flight, both pilots got distracted while flying at a height of some 5-10 metres. The aircraft lost height and touched down in a maize field near Chirsova. The captain tried to take off again but the aircraft collided at a height of 3 metres with a warehouse 26 metres behind the field and later on with a power line, crashed, caught fire and burnt out. One of the 2 pilots and one of the 2 passengers were killed and both survivors were injured.
Probable cause:
Loss of control after both pilots got distracted due to the presence of two unauthorized people on board. A low level of discipline allowed a series of infractions that led to the accident.

Circumstances:
The airplane was carrying two pilots and a local guide on crop spraying operations for the kolkhoz (collective farm) of "Put' Kommunizma" in the Pushkino district of Azerbaijan. While cruising at a height of 40-50 meters, the crew saw a flock of birds but it was too late. Several birds struck the engine that failed almost immediately. The crew attempted an emergency landing on a road but the aircraft came down in a cotton field some 12 km from Pushkino and caught fire. All three occupants were killed.
Probable cause:
Loss of control following an in-flight collision with birds. It was determined that the birds struck the cylinders n°1, 7, 8 & 9 and also the air intake of the carburetor. This caused the engine to fail and the airplane to lose speed and altitude.

Circumstances:
While completing a visual approach to Batumi Airport, the crew encountered poor weather conditions and initiated a go around procedure. The pilot-in-command completed a first turn to the right, flew for about 1,5 km then made a turn to the left. While cruising at an altitude of 550 meters at a speed of about 300-350 km/h in a flaps and gear down configuration, the airplane struck the slope of Mt Mtirala (595 meters high) located 15 km from the airport. The aircraft disintegrated on impact and all 40 occupants have been killed.
Probable cause:
ATC failed to inform the crew about the real weather conditions at Batumi Airport and the crew initiated a go around procedure in marginal weather conditions with a visibility reduced to 3 km instead of the 5 km as mentioned by ATC. In such conditions, the crew was unable to distinguish the mountain, resulting in a controlled flight into terrain.

All three occupants were killed.
Probable cause:
The pilot took the decision to fly without any copilot and with two unauthorized people on board. He lost control of the airplane following a sharp turn at low height.
