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:

The airplane was just coming out from the PZL-Mielec factory in Mielec, Poland. Three crew members and one passenger were in charge to deliver the plane to Novosibirsk via Lvov, Samara and Omsk. The crew departed Omsk at noon on the last leg to Novosibirsk and continued in good weather conditions bound to the east. While approaching Tatarsk, weather conditions deteriorated with clouds down to 150 meters above the ground. The pilot-in-command reduced his altitude in an attempt to maintain visual contact with the ground. At an altitude of 199 meters, the single engine airplane struck with its both right wings a relay antenna (202 meters high) located about 5 km northeast of Tatarsk. Out of control, the aircraft lost height and crashed 280 meters further in a snow covered field, bursting into flames. All four occupants were killed.

Probable cause:

The crew failed to prepare the flight properly and took the decision to continue to fly under VFR mode into low clouds with a below-minima visibility. The people in charge to transmit to the crew weather bulletin failed to ensure that information were accurate. A lack of discipline and wrong in-flight decisions on part of the crew were considered as contributing factors.

Circumstances:

The airplane departed Moscow-Vnukovo Airport on a schedule service to Bratsk with an intermediate stop in Omsk. On approach to Bratsk Airport, the crew encountered limited visibility due to heavy rain falls. One second after touchdown, the reverses were activated on all three engines and the airplane rolled for about 800 meters when it started to veer to the left. The pilot-in-command attempted to counteract the deviated but the airplane rolled another 526 meters when it veered off runway. It rolled few dozen meters on soft ground then came to rest, broken in two. All occupants escaped uninjured.

Probable cause:

The cause of the accident was the uncontrollability of the aircraft on a wet runway due to the complete loss of rudder efficiency at the maximum reverse engine thrust due to the design characteristics of the aircraft.

Circumstances:

Shortly after takeoff from Omsk Airport, while climbing to a height of 10 meters, the pilot-in-command encountered an unexpected situation and reduced the engine power, apparently to attempt an emergency landing. The airplane banked left then stalled and crashed inverted in flames in a field located 128 meters to the left of the runway and about 180 meters past its end. Two passengers and the copilot were seriously injured while 11 other occupants were killed. A day later, both passengers who survived died from their injuries.

Probable cause:

At Omsk Airport, strong winds forced a local technicians team to lock the aircraft rudder while parked on apron. Following negligences on part of the crew, takeoff was initiated with a locked rudder. The following findings were reported:
- The technicians failed to report to the crew that the rudder has been locked by ground personnel,
- The crew failed to follow the pre-takeoff checklist,
- The crew failed to conduct a visual inspection of the airplane prior to takeoff,
- The crew failed to follow the published procedures prior to takeoff,
- The crew failed to proceed to a test of the rudder, ailerons and elevators during the taxi procedure.

Circumstances:

After takeoff by night from Sverdlovsk-Koltsovo Airport, the crew was cleared to climb to 1,500 meters and initiated a left turn as instructed by ATC. The airplane first banked left to an angle of 35-40° and at an altitude of 1,200 meters, the left angle increased to 75-80° when control was lost. The airplane entered a dive and crashed in a huge explosion in a wooded area located 10 km from the airport. The aircraft disintegrated on impact and none of the 108 occupants survived the crash. At the time of the accident, weather conditions were considered as marginal with a visibility limited to 6 km, overcast 800 feet, wind from northwest at 15 knots and light rain.

Probable cause:

It was determined that the loss of control during initial climb was the consequence of the failure of artificial horizons as a result of a malfunction of the on-board electrical system. The combination of night, lack of visibility and flight instruments failure caused the pilot to suffer a spatial disorientation and the eventual loss of control.

Circumstances:

The aircraft was completing a cargo flight from Omsk to Surgut, carrying two passengers, a crew of 12 (among them six reserve members) and a load of 12 tons of various construction equipments. While approaching Surgut Airport by night and icing conditions, at an altitude of 400 meters and a speed of 330 km/h, the pilot lost control of the airplane that crashed in flames 15 km short of runway. The aircraft was destroyed and all 14 occupants were killed.

Probable cause:

There were severe icing conditions at the time of the accident and the crew activated all de-icing equipment. Nevertheless, it appears that following the failure of a valve, the de-icing equipment was inoperative. An excessive accumulation of ice on the fuselage, the wings and all four engines caused the loss of control.

Circumstances:

While cruising at an altitude of 9,000 meters, the copilot was able to send a short distress call and control was lost. The airplane entered a dive and the descent took about two minutes and thirty seconds before the airplane disintegrated in a wooded area located in Voznesenka, about 28 km east of the Krasnoyarsk Airport. The aircraft was totally destroyed and all 84 occupants were killed. It was later reported that all bodies shows traces of high temperature and burns.

Probable cause:

It was determined that several units of the Soviet Army Forces were involved in a training exercise in the region of Magansk and shot several ground-to-air missiles. One of them struck the left side of the airplane, penetrated the fuselage and caused a hole of 20 cm. Out of control, the airplane entered a dive and crashed.

Circumstances:

On the leg from Omsk to Irkutsk, at a distance of 160 km from the destination, the crew was informed about the deterioration of the weather conditions at Irkutsk Airport and was then diverted to Ust-Orda Airport. At this time, weather at Ust-Orda was as follow: cloud base at 250 meters, snow falls and a visibility of 3 km. On approach by night, the nose gear light was unserviceable so the captain decided to make a go around. For unknown reason, this procedure was delayed and he completed a low pass over the runway for about two km before making a turn to the left at a height of 10-15 meters when the airplane struck power cables. The aircraft stalled and crashed in flames on a hilly terrain near the airport. 46 passengers were uninjured while 19 occupants were injured. Three crew members were killed, the navigator, the radio operator and the mechanic. The aircraft was totally destroyed by a post crash fire.

Probable cause:

The decision of the captain to perform a go around was comprehensive but the very low pass (10-15 meters) above the runway was unacceptable. Investigations were able to determine that weather conditions at Irkutsk Airport were not as bad and the decision of the ATC to divert the crew to Ust-Orda was not necessary. Also, it was the first time that the pilot was flying to Ust-Orda and he did not have any knowledge about the environment at this airport, which was considered as a contributing factor.
