What happened
While operating in flight, the aircraft experienced a double engine failure. Following the loss of propulsion, the occupants were forced to abandon the aircraft via parachute. The aircraft subsequently crashed in the vicinity of Suwon.
Despite the impact and the total destruction of the airframe, there were no casualties reported among those on board. All individuals successfully exited the plane prior to the crash.
Findings
Investigations into the incident identified that the primary factor leading to the emergency was the simultaneous failure of both engines during the flight phase.
