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:
Parked at Voroshilovgrad Airport, the single engine aircraft was stolen by a pilot who decided to commit suicide due to marital problems. He took off alone and directed his aircraft into a 4-floor building where he was living (house # 10 in the 27th district of Voroshilovgrad). The aircraft was totally destroyed by impact forces and a post crash fire and the pilot was killed. The building was partially destroyed as well but no one was injured.
Probable cause:
Pilot suicide.

Circumstances:
The airplane was completing a flight from Simferopol to Kerch, carrying six members of the Ministry of the Interior. On approach, the crew encountered poor weather conditions with fog, clouds down to 100 meters above the ground and a visibility limited to 500 meters. On final, at a speed of 220 km/h, the pilot-in-command decided to reduced his altitude to establish a visual contact with the ground when the airplane struck a concrete block of a power line. Flying at a height of 17 meters below the runway altitude, the airplane struck a house and crashed in flames some 2,610 meters short of runway. All four crew members and two passengers were killed while five other occupants were killed.
Probable cause:
The crew continued the approach below the glide without visual contact with the runway and ground. The accident was caused by the combination of the following factors:
- Overestimation of the vertical speed,
- Poor altimeter monitoring,
- Possible wrong altimeter setting,
- Absence of a radar at the airport allowing ATC to monitor the aircraft's approach path,
- Low visibility due to fog,
- Lack of information regarding weather conditions at destination.

Circumstances:
On approach to Vinnitsa Airport, the crew encountered poor weather conditions with fog, low clouds and freezing rain. Due to poor visibility, the captain decided to abandon the approach and made a go-around. Few minutes later, during a second attempt to land in similar conditions, the captain decided to make a second go-around and requested full power. At this time, the airplane banked left to an angle of 20-40° then stalled and crashed in flames 850 meters short of runway. The aircraft was totally destroyed and all 48 occupants were killed.
Probable cause:
The loss of control on short final was caused by an aerodynamic stalled for a reason which could not be determined with certainty. However, it was reported that a delay of 3 to 5 second elapsed from the decision to make a go-around and the selection of the speed levers in a forward position which could contribute to the stall.

Circumstances:
On approach to Voroshilovgrad Airport, while descending from 1,200 to 600 meters, the airplane went out of control. It dove into the ground and crashed in a huge explosion in a field located 13 km from the runway threshold. The aircraft was totally destroyed upon impact and all 65 have been killed.
Probable cause:
It was determined that a portion of 13 m2 detached from the upper surface of the right wing during the approach, causing the aircraft to be uncontrollable. Investigations were unable to determined the exact cause of this 'structural' failure as no technical problems or any structural issues with rivet was apparently found.
