What happened
On the flight path from Petrozavodsk Airport toward Vaskovo Airport in Arkhangelsk, an aircraft entered a fatal descent while climbing. During the ascent, the plane transitioned into cloud cover, at which point the pilot-in-command lost control of the vessel. The aircraft subsequently entered a dive and struck the surface of the iced Urozero Lake. Upon impact, the plane partially submerged in the water. There were seven fatalities among the occupants, with no survivors reported from the crash.
Findings
Investigations into the accident revealed that the failure of the artificial horizon was a critical factor in the loss of control. As the aircraft climbed into the clouds, the pilot-in-command experienced spatial disorientation due to the malfunctioning instrument, which led to the uncontrolled dive and subsequent impact with the lake.
