Circumstances:
The aircraft was completing a cargo flight from Yakutsk to Sangar, carrying a load of 3,100 kilos of apples. Descending to Sangar Airport by night, while at an altitude of 600 meters, the pilot informed ground he located the airport. Twice, the airplane overflew the airfield without landing and the crew was apparently unable to determine his position with certainty. While flying at low height, the right wing struck trees and was sheared off. Out of control, the airplane crashed on the southwest slope of Mt Vataala Hayata located near the village of Smorodinny, about 8 km southeast of the airport. The aircraft was destroyed by impact forces and a post crash fire and all five crew members were killed.
Probable cause:
A general power failure occurred in Sangar few minutes before the arrival of the aircraft. Due to the night and the presence of fog, the visibility was less than 3 km and the pilots interpreted the lights of Smorodinny village as those of Sangar and thus started the approach prematurely, causing the aircraft to struck trees and to crash. For reasons unknown, the crew had not been informed by ATC that Sangar was plunged into darkness and bad weather at destination.

Circumstances:
The aircraft was performing a cargo flight from Yakutsk to Zyrianka with an intermediate stop at Oymyakon, carrying two passengers, a crew of four and a load of 2,253 kilos of potatoes. While cruising at an altitude of 1,600 meters in clouds, the airplane went out of control, entered a dive and crashed in a wooded area located 95 km west of Oymyakon. The wreckage was found two days later in an isolated area. The aircraft was destroyed and all six occupants have been killed.
Probable cause:
It was determined that the crew failed to follow the procedures in flight and failed to pay attention to the fuel selector that was switched to an empty tank, causing both engines to stop. There was fuel remaining in other tanks but the crew failed to switch the fuel selector in due time. Due to fuel exhaustion, both engines failed and the airplane went out of control while flying in autopilot in clouds.

Circumstances:
The crew was performing a local test flight at Lukhovitsy-Tretyakovo Airport. While completing a third turn on approach, the crew activated the feathering system on the engine number two. Shortly later, while an altitude of 80-100 meters, the airplane banked left, lost height and speed, stalled and struck the ground. On impact, the undercarriage were sheared off and the airplane slid for dozen yards before coming to rest with its left wing broken. All six crew members were unhurt while the aircraft was damaged beyond repair.
Probable cause:
Loss of control on final approach due to loss of thrust on engine number one after the propeller went into autorotation, causing negative thrust.

Circumstances:
On the leg from Kazan to Sverdlovsk-Koltsovo Airport, while cruising at an altitude of 1,200 meters, both engines failed simultaneously. The pilot-in-command reduced his altitude and attempted an emergency landing when the airplane struck trees and crashed in flames in a wooded area located about 120 km west of Sverdlovsk. The wreckage was found the following morning at 0800LT. All five crew members and four passengers were killed while 17 other occupants were injured. The aircraft was destroyed.
Probable cause:
In-flight failure of both engines due to a fuel exhaustion. This was the result of a poor flight preparation on part of the crew who failed to fuel the aircraft with a sufficient quantity prior to departure. It was determined that a total of 1,108 kg of fuel was in the tanks, about 550 kg less than the necessary amount for this routing.

Circumstances:
While cruising at an altitude of 6,100 meters on a flight from Moscow-Vnukovo Airport to Sochi-Adler Airport, the generator on engine number three failed. Debris punctured a hydraulic line and the fluid caught fire while in contact with high temperature elements of the engine. As the fire extinguishing system failed to work properly, the crew decided to shut down all three other engines and completed a gear up landing in a field. The airplane slid for several yards and came to rest. All 97 occupants were evacuated safely.
Probable cause:
Failure of the generator on engine number 3 for unknown reason. This caused the rupture of a hydraulic line and the fluid caught fire while contacting engine elements. The reason of the dysfunction of the fire extinguishing system remains unknown.

The crew was performing a cargo flight from Irkutsk to Khabarovsk with an intermediate stop in Chita, carrying a load of brake linings and hoses for a total weight of 3,031 kilos. While approaching Chita-Kadala Airport by night, the airplane was too low, struck trees and crashed on the slope of Mt Cherskogo located 11 km short of runway threshold. The wreckage was found 170 meters below the summit and all five crew members were killed.
Probable cause:
For unknown reason, the crew started the descent prematurely and was at an insufficient altitude of 700 meters instead of 1,200 meters when the airplane struck the mountain. Due to the lack of visibility caused by night, the crew was unable to distinguish the mountain. It was also reported that ATC assistance was inappropriate, which was considered as a contributing factor.

Circumstances:
The crew departed Nizhneangarsk Airport at 0843LT on a cargo flight to Dovyren and Irkana, carrying a load of six diesel drums. Twelve minutes later, the crew reported he was climbing to an altitude of 1,200 meters in good weather conditions. About ten minutes later, the single engine airplane crashed in a mountainous area located 7-10 km from Dovyren. As the aircraft failed to arrive at Dovyren, SAR oeprations were conducted and the wreckage was found a day later. Both crew members were killed.
Probable cause:
It was determined that one of the propeller blades failed in flight and struck and broke the windshield. In low visibility caused by snow falls, the crew was unable to attempt an emergency landing as he was flying over a mountainous area. The failure of the propeller blade was caused by a faulty manufacture.
