Circumstances:

After takeoff from Krasnoyarsk-Cheremshanka Airport, while climbing to an altitude of 2,040 meters at a speed of 480 km/h, the right engine (engine n°3) suffered an uncontained failure and caught fire. The crew declared an emergency and was cleared to return for an emergency landing. On final approach, the aircraft banked right then nosed down and crashed at a speed of 425 km/h 3,200 meters short of runway threshold and disintegrated on impact, some 11 seconds prior to landing. A passenger was seriously injured while 110 other occupants were killed.

Probable cause:

It was determined that the failure of the right engine was the consequence of a fatigue failure of the first stage low pressure compressor disk due to metallurgical and manufacture defect. A fire erupted in the right engine and quickly spread to the right wing and the engine n°2 because the crew forgot to close the fuel valve.

Circumstances:

The twin engine aircraft departed Kostroma Airport at 0809LT on a flight to Ivanovo, carrying eight passengers and two pilots. After takeoff, while climbing in marginal weather conditions, the crew was instructed to report once the altitude of 1,800 meters would be reached but the crew failed to respond. The aircraft entered an uncontrolled descent and crashed in a wooded area located 11 km north of the airport. The aircraft was destroyed and all 10 occupants were killed.

Probable cause:

The exact cause of the accident could not be determined with certainty as investigations were hampered because the aircraft was not equipped with CVR/FDR. Nevertheless, it is believed that the pilot-in-command lost control of the airplane after he suffered a spatial disorientation caused by the malfunction/dysfunction of the horizontal gyro.

Probable cause:

It was determined that the crew failed to prepare the flight properly. No weight and balance sheet was computed prior to takeoff and it was determined that the CofG was 5,8% aft the limit.

Circumstances:

Following an uneventful flight from Krasnodar, the crew started the approach to Omsk Airport in a reduced visibility due to the night and rain falls. The aircraft landed at a speed of 270 km/h and about one second later, the captain noticed the presence of vehicles on the runway. He initiated a turn to the right when the left wing struck the vehicles. Upon impact, all three vehicles were destroyed and the four people on board were killed instantly. Out of control, the airplane turned to the left, veered off runway and came to rest upside down, broken in two, bursting into flames. Four crew members and one passenger survived while all 174 other occupants were killed.

Probable cause:

It was determined that the person in charge of the runway maintenance allowed a team of three vehicles to enter the runway for maintenance and then fell asleep. Thus, he failed to inform ATC about the presence of ground vehicles on the runway and the Air Traffic Controller based in the Airport Tower was unable to see the vehicles due to poor visibility caused by night and rain falls. As ATC was not aware of the presence of ground vehicles, he was unable to inform the crew prior to landing. Also, it was reported that the vehicles dispatched on the runway were not equipped with rotating flashing beacons and radios that would allow their personnel to listen the tower frequency.
