Accident Details
An airplane departed from Petrozavodsk Airport on a flight to Vaskovo Airport in Arkhangelsk. During the initial climb after takeoff, the aircraft entered cloud cover. While climbing through the clouds, the pilot-in-command lost control of the airplane. The airplane subsequently entered a dive and crashed into the iced surface of Urozero Lake. The impact caused the aircraft to partially sink. All seven individuals aboard the aircraft were killed in the accident.
Probable Cause
The official investigation into the accident determined the probable cause. It found that the artificial horizon instrument failed after takeoff. Due to this failure, while the airplane was climbing into clouds, the pilot-in-command experienced spatial disorientation. This spatial disorientation resulted in the pilot losing control of the airplane, leading to the dive and crash.
