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.

Total fatalities:

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.

Circumstances:
One hour and 16 minutes after takeoff, while flying in formation with other similar aircraft, the captain informed the leader that engines n°1, 2 and 4 failed. He left the formation and reduced his altitude in an attempt to divert to Chita-Kadala Airport. Unable to reach the airport, the captain lowered the landing gear, downed the flaps and completed an emergency landing in an open field. Upon touchdown, the aircraft lost its undercarriage and slid for few dozen meters before coming to rest, bursting into flames. The aircraft was destroyed by fire and all six crew members were killed.
Probable cause:
It was determined that all three engines n°1, 2 and 4 failed because the fuel was contaminated by water. Nevertheless, the crew failed to follow emergency procedures.

The captain let the copilot flying, which was against the published procedures. Also, the crew allowed an illegal passenger to embark.
