Circumstances:
Shortly after takeoff from runway 32 at Seoul-Gimpo Airport, while in initial climb, a propeller blade on the engine number three detached, struck the fuselage and penetrated the cabin, killing four passengers instantly. Doing so, the ailerons and rudder cables were cut. Before the crew would be able to shot down the engine number three and to feather its propeller, both other blades detached and struck the engine number four. The crew contacted ATC and received the permission for an emergency landing on runway 14. Shortly later, the airplane went out of control and crashed in flames in a canal located near the Han River, about 15 km north of the airport. 24 people were injured while 113 other were unhurt. Unfortunately, 22 occupants were killed, among them three crew member of which both pilots.
Those killed were:
