Incident
On an unspecified date, a cargo aircraft with registration CCCP-47645 departed Pevek at approximately 1015 local time on a flight to Palyavam. The aircraft carried one passenger, two pilots, and a load of explosive ammonite. Later, another AN-2 approaching Palyavam informed air traffic control that landing was impossible due to poor weather conditions and decided to return to Pevek. Air traffic control attempted to contact CCCP-47645 but received no response.
Search and Rescue
After the aircraft was declared missing, search and rescue operations were conducted. Five days later, on February 26, the wreckage was discovered at an altitude of 450 meters on the slope of Mount Karpung, which has a height of 906 meters. The location was approximately 140 kilometers southeast of Pevek and 20 kilometers south of the planned route. The aircraft was destroyed, and all three occupants were killed.
Investigation
An investigation was conducted to determine the cause of the accident. The official findings indicated that the crew likely continued flight under visual flight rules in instrument meteorological conditions characterized by low clouds. Contributing factors included poor flight preparation, poor flight organization, lack of air traffic control assistance, and an improper weather forecast.
Probable Cause
The accident was probably the consequence of the decision of the crew to continue under VFR mode in IMC conditions (low clouds). Contributing factors were poor flight preparation, poor flight organization, lack of ATC assistance, and improper weather forecast.
