Circumstances:
After 33,5 seconds during the takeoff roll, after a distance of 975 metres and at a speed of 210 km/h, the engine n°4 failed and its propeller automatically feathered. For unknown reasons, the crew failed to identify this failure and the pilot-in-command started the rotation (elevator -26°) at an insufficient speed of 238 km/h instead of the recommended 250 km/h. After liftoff, the aircraft started to roll to the right, causing the right wing to struck the ground two seconds after rotation. The went out of control, lost its undercarriage, slid for about 300 metres and came to rest, bursting into flames. All nine occupants escaped with various injuries and the aircraft was destroyed by fire.
Probable cause:
Failure of the engine n°4 due to an incorrect setting of the propeller speed control system.

Few minutes after takeoff from Yakutsk-Magan Airport, while cruising at an altitude of 1,150 metres at a speed of 180 km/h, the engine started to vibrate and lost power, Also, the oil pressure dropped and the speed decreased. The captain attempted an emergency landing in a swampy area when the aircraft rolled for about 32 metres and nosed over. A passenger was killed and all other occupants were injured, four seriously.
Probable cause:
Engine failure following the failure of the first cylinder and piston due to fatigue.

The aircraft stalled during initial climb because snow and ice/frost remained on the wings, tail and fuselage. The following factors were identified:
- The crew failed to inspect the aircraft prior to takeoff,
- The crew failed to prepare the flight according to published procedures,
- The crew failed to proceed to an appropriate pre-takeoff deicing/cleaning.

Circumstances:
A Mil Mi-8 registered RA-24247 just landed at Naryan-Mar Airport after completing a local flight with eight passengers and three crew members on board. Its crew was instructed to vacate via taxiway 4. Following an uneventful flight, the crew of the Antonov AN-12 was cleared to land on the same runway two minutes later. After touchdown, the aircraft collided with the helicopter. Both aircrafts were destroyed and while all nine people on board the Antonov were injured, among the 11 people on board the helicopter, eight were killed and three were injured. At the time of the accident, the visibility was reduced to 500 metres.
Probable cause:
The airport of Naryan-Mar is controlled by both civil and military services. The helicopter has been cleared to land by civil ATC and less than two minutes later, the aircraft was cleared by military ATC to land on the same runway. A lack of coordination between both ATC services was identified as the separation between both landings was insufficient. Nevertheless, it was also reported that the crew of the Antonov failed to follow ATC message after the controller in the tower instructed the crew to initiate a go-around procedure. The crew misinterpreted this order thinking ATC was referring to the lack of visibility and not to the presence of another aircraft on the runway.

Circumstances:
The four engine aircraft departed Irkutsk-2 Airport on a cargo flight to Cam Ranh Bay, with an intermediate stop in Vladivostok, carrying 15 passengers, eight crew members and a load consisting of two Sukhoi SU-27UB fighters to be delivered to the Vietnam Air Force. Three seconds after takeoff from runway 14 at Irkutsk-2 Airport, at a height of 5 metres, the engine n°3 failed. Six seconds later, at a height of 22 metres, both left engines n°1 and 2 also failed. The aircraft pitched up and entered a high angle of attack, climbed to a maximum height of about 66 metres then rolled to the left and crashed onto several buildings located 1,600 metres from the runway end. The aircraft was totally destroyed by impact forces and a post crash fire as well as several buildings. All 23 occupants and 45 people on the ground were killed. Hundred other people on the ground were injured, some seriously.
Probable cause:
The exact cause of the engine failure could not be determined with certainty. It is known that engines of this series had problems with gas-dynamic stability, especially at high angle of attack.

Circumstances:
The aircraft was completing a cargo flight from Istanbul to Bryansk, carrying one passenger, eight crew members and a load of various goods. On approach to Bryansk Airport, the crew encountered poor weather conditions with fog. The horizontal visibility was estimated to be 450 metres, the vertical visibility 80 metres with a RVR of 1,000 metres. On final approach, the pilot-in-command was unable to establish a visual contact with the runway so he decided to initiate a go-around procedure. Few minutes later, the crew attempted a second approach in similar weather conditions. Nevertheless, the crew continued the approach when the aircraft landed hard. Out of control, it veered off runway and came to rest. All nine occupants were injured and the aircraft was damaged beyond repair.
Probable cause:
The following contributing factors were identified:
- The crew was tired following an over 20 hours duty period without any rest time,
- The crew decided to leave Istanbul without any rest time period,
- Information transmitted to the crew concerning weather forecast for Bryansk Airport were inaccurate,
- The crew decided to continue the approach and to descent below the MDA without any visual contact with the runway lights until the aircraft impacted the ground.

Circumstances:
The crew was engaged in a spraying mission in Novomusino. After departure, at a height of 50 metres, the crew raised the flaps and continued at a speed of 140 km/h. Approaching the area to be treated, the crew realized his position was incorrect and elected to gain speed and height when the aircraft stalled and crashed. Both pilots escaped uninjured and the aircraft was damaged beyond repair.
Probable cause:
The accident was the consequence of mistakes made by the crew in choosing the route and the engine operating mode which led to the need to increase the vertical speed with a lack of thrust below the safe altitude. The aircraft adopted a high angle of attack, lost speed and struck a hillside.
