What happened
During flight operations within the vicinity of Chongju, a twin-engine aircraft was struck by anti-aircraft fire. This engagement resulted in the immediate loss of power to one of the engines. Following the engine failure, the aircraft proceeded through its flight path until it impacted a mountain slope located near the Chongju area.
There were no survivors of the impact. The incident resulted in three fatalities among the crew members on board.
Findings
Investigations into the crash determined that the primary factor leading to the loss of the aircraft was the damage sustained from ground-based weaponry. The impact of anti-aircraft fire caused an engine to become inoperative, which ultimately led to the uncontrolled descent and subsequent crash on the mountain terrain.
