Incident Overview
An aircraft operating a flight from Mys-Kamennyy to Vorkuta encountered deteriorating weather conditions en route, with limited visibility due to low clouds. The crew decided to return to Mys-Kamennyy, but this decision was made too late. While cruising in clouds at an altitude of 452 metres, the aircraft struck the slope of Mt Konstantinov Kamen, which rises to 492 metres. The wreckage was located several hours later.
Occupants and Injuries
The aircraft carried eight passengers and two pilots. All eight passengers suffered light to moderate injuries, while both pilots were killed.
Probable Cause
The official investigation determined that the crew was flying under visual flight rules (VFR) in instrument meteorological conditions (IMC). At the time of the accident, the cloud base was approximately 200 metres. The crew lost orientation and was unable to determine their exact position. The wreckage was found about 40 kilometres off the planned route. The accident was attributed to controlled flight into terrain (CFIT).
