Overview
A cargo flight operating from Turukhansk to Lake Munduiskoye ended in a fatal accident when the aircraft crashed into a rocky slope. The flight was conducted under visual flight rules (VFR) despite weather conditions that did not permit such operations due to low clouds.
Flight Details
The aircraft departed from Turukhansk en route to Lake Munduiskoye. The crew elected to fly under VFR, contrary to the prevailing weather which featured low clouds. This decision led to a deviation from the prescribed flight path.
Accident Sequence
During the flight, the aircraft deviated from its intended route and entered clouds. Subsequently, it crashed at an elevation of 395 metres into the rocky slope of a hill located approximately 72 kilometres northwest of Turukhansk. The hill, which rose to 410 metres, was not depicted on the flight map used by the crew.
Investigation Findings
The official investigation determined that the accident occurred because the crew continued to operate under VFR mode in adverse weather conditions. The aircraft's impact with the unmarked terrain resulted in the destruction of the aircraft and the loss of all three occupants.
Probable Cause
The crew continued under VFR mode in adverse weather conditions.
