On November 10, 2023, a TR-301 aircraft, registration RA-84566, was operating a scheduled cargo flight from Pevek airfield to the settlement of Polar. The flight task had been approved following a request from LLC 'Artel of Prospectors Polar' for the transport of goods.
During the pre-flight phase at Pevek airfield, the captain received weather updates via the Automated Meteorological Information System. However, it was later determined that the captain did not undergo the required pre-flight medical examination, which was a violation of Federal Aviation Regulations.
While operating in mountainous terrain, the aircraft collided with a mountainside. The accident occurred during the day under meteorological conditions characterized by heavy rainfall.
The flight was intended to operate within airspace classes C and G. The investigation noted that the crew proceeded with the flight despite forecasted conditions that were not suitable for the planned operations.
