Circumstances:
The single engine airplane departed Zlatoustovsk Airfield at 1840LT on its last leg back to Ekimchan, carrying three passengers and a crew of two. Ten minutes later, weather conditions worsened and while cruising at an altitude of 1,434 meters in cloud, the airplane struck the slope of a mountain located 22 km east of Ekimchan. The wreckage was found two days later, 94 meters below the summit and 10 km off course. The aircraft was destroyed and all five occupants have been killed.
Probable cause:
It was determined that the crew was the crew continued the flight under VFR mode in IMC conditions and failed to see the mountain while flying in clouds. Analysis revealed that the aircraft was off course by 10 kilometers at the time of the accident and that both pilots were intoxicated with an alcohol blood level of 2 ‰ for the captain and 1.34 ‰ for the copilot.

Circumstances:
While cruising in good weather conditions at an altitude of 2,700 meters and at a speed of 300 km/h, control was lost. The airplane nosed down and entered a dive. Elements from the stabilisers and from the wing tips detached during the descent and the aircraft crashed in a nose-down attitude of 15-20° and at a speed of 330 km/h in a field located 3 km southwest of Nashchekino, some 9 km off course. The airplane was totally destroyed upon impact and all six occupants have been killed. The aircraft was on its way from Tbilisi to Myachkovo with an intermediate stop in Krasnodar, carrying 20 empty gas bottle and few boxes containing metal parts for a total weight of 1,792 kg.
Probable cause:
The exact cause of the accident could not be determined with certainty. However, it was reported that the aircraft CofG was too far front and that the cargo was not properly secured. Both engines were running at impact and there was no fire prior to final impact. It is possible that the loss of control was also the result of atmospheric turbulences or an unexpected disconnection of the automatic pilot system.

Circumstances:
Flight SU1912 departed Odessa Airport in Ukraine on July 24 to Vladivostok with intermediate stops in Kiev, Chelyabinsk, Novosibirsk, Irkutsk and Khabarovsk. While descending to Irkutsk-Intl Airport in the morning, the crew encountered poor weather conditions with low clouds and rain falls. As the visibility was limited, the crew was unable to locate the runway and obtained an ATC assistance on final. Unfortunately, the aircraft was unstable and the crew was instructed by ATC to turn to the right to reach the glide as the aircraft was descending to the left. At an excessive vertical speed and an approach speed 32 km/h below the prescribed approach speed, the aircraft banked left and right. The right main gear struck the runway surface 154 meters past the runway threshold and the left main gear touched the ground 183 meters from the threshold. The ground impact was in excess of the g-load certification. After touchdown, the airplane went out of control, deviated from the centerline to the left, lost its left wing and came to rest in flames after a course of 500 meters to the left of the main runway. 97 occupants, among them four crew members, were killed, while 29 other occupants were injured. The aircraft was destroyed.
Probable cause:
One of the flight data recorder was out of service at the time of the accident due to lack of sufficient technical controls. The second data recorder disconnected when the right main gear impacted the runway surface. Investigations revealed that the aircraft' speed was 32 km/h lower than the prescribed speed when the vertical speed was too high, which prevented the pilots to complete a correct touchdown and avoid the violent impact with the runway surface. Aerodynamic forces recorded at impact exceeded the certification of the aircraft, resulting in a loss of control and then the failure of the left wing. The probable cause of the loss of speed on short final could be the combination of a series of erroneous actions on part of the flying crew, coupled with incorrect speed indication, possibly be due to a leak of the power system that occurred at low altitude and in marginal weather conditions.

Circumstances:
On a crop-spraying flight for the kolkhoz (collective farm) 'Pobeda' at Kamennaya Sarma (Buzuluk district of the Orenburg region), the engine failed (probably due to a carburetor problem) while the aircraft was flying at a height of some 20-25 metres near Kamennaya Sarma. As an immediate forced landing was not possible due to the terrain configuration, the pilot initiated a left turn when the aircraft lost height, stalled and crashed. A pilot was killed while the second pilots was injured.
Probable cause:
Engine failure caused by carburetor problem.
