Circumstances:
After departure from an airfield located in a mountainous area, the single engine airplane did not reach the required speed for climb and at a distance of about 1,050 meters from the aerodrome, at a height of 15-20 meters, it struck tree tops. The captain shut down the engine and completed an emergency landing in a wooded area. While the aircraft was damaged beyond repair, all 12 occupants escaped uninjured.
Probable cause:
Failure of the crew to release the flaps prior to takeoff that was completed at a too low speed. A lack of crew training in such operations was considered as a contributing factor.

Circumstances:
During the takeoff roll at Moscow-Bykovo Airport, the flight engineer mistakenly raised the landing gear while the aircraft was still on the ground. Despite the situation and that the flaps were not extended, the captain decided to continue the takeoff procedure. The airplane failed to lift off, overran, struck a perimeter fence, crossed a road, collided with buildings and came to rest in flames. All 47 occupants escaped with injured while the aircraft was destroyed.
Probable cause:
Wrong take off configuration and poor coordination on part of the crew. It was determined that the crew failed to follow the pre-takeoff checklist and forgot to extend the flaps. Also, the flight engineer raised the landing gear prematurely while the aircraft was still on the ground.

Circumstances:
At 1858LT, a technical issue occurred on the right main gear during the takeoff roll. The captain decided to continue and after rotation, during initial climb, it was not possible to raise the landing gear. The crew informed ATC about his situation and completed several circuits over the region to burn fuel. A bit more than an hour later, the crew returned to Krasnoyarsk-Severny Airport and completed an emergency landing in a grassy area located 100 meters to the right of the main runway. The airplane landed at a speed of 205 km/h. After a course of about 70 meters, the right main gear collapsed and the airplane rolled for few dozen meters before coming to rest in flames. All 53 occupants escaped the cabin but three passengers were seriously injured by fire. Two of the survivors died from their injuries two and three days later.
Probable cause:
Failure of the right main gear due to fatigue cracks in the main cylinder.

Circumstances:
On approach to Florianópolis-Hercílio Luz Airport, the crew encountered poor weather conditions with thunderstorm activity and heavy rain falls. The approach was abandoned and the captain initiated a go-around. Few minutes later, while completing a second attempt to land, the crew failed to realize that the airplane was not properly aligned. At a higher speed than prescribed, the airplane struck the top of a hill and crashed in flames about 26 km from the airport. Three passengers were rescued while 55 other occupants were killed. At the time of the accident, the airplane was approaching the airport below the glideslope and off course. It appears that an inspector pilot was at control at the time of the accident.
Probable cause:
The crew misjudged distance, speed and altitude during an approach completed in marginal weather conditions. The following contributing factors were reported:
- Lack of flight supervision,
- Lack of crew coordination,
- Improper use of engines,
- The pilot-in-command failed to initiate a second go-around,
- Lack of visibility due to poor weather conditions.
