Circumstances:
Following an uneventful flight from Vnukovo Airport at an altitude of 7,200 meters, the crew was cleared to approach Kharkiv-Osnova Airport and to descent to 1,500 meters. While approaching at a speed of 400-500 km/h with a rate of descent of 6 meters per second, the airplane lost its both wings, dove into the ground and crashed in a wooded area located in Rus'ka Lozova, about 25 km north of Kharkiv-Osnova Airport. The aircraft was totally destroyed and all 122 occupants were killed.
Probable cause:
It was determined that a structural failure of the center section lower panel caused the failure of both wings due to fatigue cracks. The rate of descent and the presence of atmospheric turbulences were considered as contributing factors. Investigations revealed that this portion of the aircraft could not be inspected by technicians during a maintenance process due to a faulty conception of the aircraft, thus the fatigue fractures could not be detected in time. Following this tragedy, the Antonov AN-10 would not be operated anymore in passenger service.

Circumstances:
The crew was involved in a crop-spraying mission for the kolkhoz (collective farm) of Karl Marx located in Devyaternya (Argyz district of Tatarstan). He decided to takeoff from an area facing a forest and after liftoff, while climbing, the airplane struck birch trees (24 meters high) and crashed in flames 1,162 meters from the departure point. The aircraft was destroyed by a post crash fire and both pilots were killed. Weather conditions were considered as good at the time of the accident.
Probable cause:
It was determined that the crew took the wrong decision in taking off facing the wooded area. The presence of orographic waves was considered as a contributing factor.

Circumstances:
The three engine aircraft departed Irkutsk-Magan Airport at 2229LT bound to the north, cruising at an altitude of 6,000 meters. Weather conditions en route were good. While descending to Bratsk Airport, the crew was informed about the last weather bulletin with no precipitations and a visibility of 50 km. However, during the night approach, weather conditions deteriorated with heavy mixed rain/snow showers and a visibility limited to one km. On short final, the airplane lost height then struck trees and crashed in flames 225 meters further, about 1,250 meters short of runway threshold. The airplane was destroyed by impact forces and a post crash fire and all 18 occupants were killed.
Probable cause:
It was determined that ATC in Bratsk transmitted to the crew a wrong weather bulletin that was referring to weather conditions at 2315LT. Unfortunately, ATC attempted without success to obtain an updated weather briefing and transmitted inaccurate information to the crew. On final, heavy snow/rain showers associated with downdraft and unfavorable winds caused the aircraft to lose height and to crash. The assumption that the crew inadvertently selected the reverse thrust during final approach was not ruled out.

Circumstances:
On a flight from Chernivtsi to Odessa, the aircraft deviated from the prescribed flight path to the south by 15 km in poor visibility and rain. It entered an area near Glinoye (Grigoriopol district of Moldova) where two radio masts were located (only one of them was indicated on the charts, but with wrong coordinates). The pilot was able to avoid the first mast (350 meters) but not the second. At a height of 200 meters, the single engine airplane collided struck the second one (260 meters high), caught fire and crashed 280 meters further on in a field of the sovkhoz (state farm) Karmanovo. All 3 crew and the sole passenger were killed.
Probable cause:
Weather information transmitted to the crew did not reflect the reality and the pilot encountered low ceiling and low visibility due to rain falls. It was established that the antenna struck by the airplane was not properly marked and its coordinates were wrong as its real position was 35 km to the east.

Out of control, the airplane crashed upside down into a water filled ravine located 258 meters further. The wreckage was found 500 meters southwest of Vyezdnoye. Both pilots were killed.
Probable cause:
The crew failed to follow the minimum safe altitude for such operation.

After takeoff, while climbing to a height of 60 meters with flaps up, the airplane banked left to an angle of 45° then stalled and struck the ground. Out of control, it crashed in a snow covered field and came to rest. A passenger was killed while three other occupants were seriously injured. The aircraft was destroyed. At the time of the accident, wind was gusting from 110° at 54 km/h with an OAT of -15° C.
Probable cause:
It was determined that the crew forgot to position the flaps down for takeoff.
