Circumstances:
The aircraft departed Anapa Airport at 1505LT and climbed to the assigned altitude of 11,700 metres. Due to the presence of stormy weather ahead, the crew was cleared to modify his route and changed heading to avoid the thunderstorm area with CB's up to 15 km. The aircraft encountered severe turbulences and climbed from 11,961 metres to 12,794 metres within 10 seconds, reaching a super critical angle of attack of 46° with a speed dropping from 350 km/h to zero, causing all three engines to stop. The crew was able to send a brief message then the aircraft entered an uncontrolled descent in a flat spin. At an altitude of 3,300 metres, the crew informed ATC that control was totally lost. The aircraft crashed in a prairie located near Novgorodskoye, about 45 km northwest of Donetsk. It was totally destroyed by impact forces and a post crash fire, and all 170 occupants were killed.
Probable cause:
The cause of the accident was a loss of control in manual flight mode after the aircraft reached a super critical angle of attack, causing a stall with the subsequent transition to a flat spin and collision with the ground with a large vertical velocity. The following contributing factors were identified:
- Poor crew coordination,
- Failure of the crew to follow the flight manual instructions to identify and prevent a stall condition,
- The crew training methods used were insufficient to demonstrate the dangers of manual flight at high altitudes.
- Poor crew coordination,
- Failure of the crew to follow the flight manual instructions to identify and prevent a stall condition,

Circumstances:
Following a night takeoff from Anapa Airport, the crew retracted flaps prematurely. This caused the aircraft to lose height and to strike trees located 1,250 meters past the runway end and 150 meters to the right of its extended centerline. The airplane suffered damaged to its left engine and stabilizer but the crew was able to continue to climb. Following a short traffic pattern, the crew was returning to the airport when the airplane stalled and crashed in shallow water near Vityazevo, about 6 km west of Anapa Airport. The aircraft was destroyed and all nine occupants were killed. The accident occurred six minutes and 464 second after liftoff.
Probable cause:
Premature retraction of flaps after takeoff.

Circumstances:
The aircraft was completing a flight from Rostov-on-Don to Kerch in limited visibility due to cloudy conditions when, at an altitude of 5,700 metres, it collided with an Aeroflot Antonov AN-24RV. Registered CCCP-46518, the AN-24 was flying from Donetsk to Sochi with 52 people on board. Following the collision, both aircraft entered a dive and crashed into the Black Sea about 37 km south of Anapa. Both aircraft sank by a depth of about 500 metres and none of the 70 occupants survived the crash.
Probable cause:
The in-flight collision was the consequence of mistakes committed by the air traffic controller in charge of the western sector of the Krasnodar area who violated the published procedures and failed to provide the minimum separation of 600 meters required for both aircraft prior to transfer them to the Anapa sector. The lack of visibility due to significant cloud cover was considered as a contributing factor, as well as poor ATC coordination between various sectors.
