Circumstances:
The aircraft was performing a special flight from Mys Schmidta to Moscow with polar researchers from the Soviet Air Force on board. On the leg from Arkhangelsk to Cherepovets, the crew encountered poor weather conditions and was flying at an insufficient altitude when the airplane struck the slope of Mt Belaya located in the region of Fedorovskaya, about 315 km southwest of Arkhangelsk. The aircraft was destroyed and all 18 occupants have been killed. At the time of the accident, weather conditions were as follow: visibility 4 km below cloud layer at 300 meters, fog, wind at 10 km/h and rain.
Probable cause:
It was determined that the captain decided to continue the flight at an insufficient altitude in poor weather conditions (below minima). Informations related to weather conditions were incomplete, which was considered as a contributing factor.

Circumstances:
The flight was performed at 3,000 meters under VFR mode above clouds. But while approaching Syktyvkar, weather conditions worsened with thunderstorm activity. The crew elected to modify his route to avoid this poor weather area when control was lost. The airplane entered a dive, lost its both wings and eventually crashed in flames in a dense wooded area located 87 km southwest of the Syktyvkar Airport. The wreckage was found 11 days later, on July 31. The airplane was completely destroyed and all 23 occupants were killed. The right wing and the right engine were found 80 meters from the main fuselage.
Probable cause:
It was determined that the loss of control was caused by the combination of strong atmospheric turbulences and vertical downdraft encountered while the aircraft was flying in a low pressure area. During the dive, excessive G loads caused the wings to detach and the aircraft became totally uncontrollable. The lack of assistance on part of the meteorology services was considered as a contributing factor as no one transmitted any information to the crew about the deterioration of the weather conditions and the presence of a thunderstorm on the flight path.
