Accident
An aircraft on approach to Bangkok-Don Mueang Airport crashed about 6 km short of the runway. The accident occurred during final approach in poor weather conditions with reduced visibility due to heavy rainfall. The aircraft struck the ground and was destroyed. Of the occupants, 14 were rescued and 76 were killed.
Investigation
The investigation determined that after passing the outer marker, the crew did not have visual contact with the ground because of heavy rain. The aircraft passed the decision height and subsequently struck the ground, resulting in the crash.
Probable Cause
The probable cause was that after passing the outer marker without visual contact due to heavy rain, the crew passed the decision height, leading to the aircraft striking the ground. A loss of altitude caused by possible windshear was not ruled out.
