Accident
The accident occurred during the approach to Bada Airfield. Weather conditions were poor with low visibility due to heavy rainfall. On final approach, the four-engine aircraft collided with a hill that was 140 meters high, located 5,200 meters short of the runway and 430 meters to the right of its extended centerline. The aircraft was destroyed by the impact and a subsequent fire. All 47 occupants on board were killed.
Investigation
The official investigation determined that the crew continued the approach despite low visibility and failed to execute a go-around even though they had not established visual contact with the runway. Additionally, the aircraft was not properly aligned on the approach path.
Probable Cause
The probable cause was identified as the crew's decision to continue the approach in low visibility and their failure to initiate a go-around when no visual contact with the runway was established, combined with the aircraft not being correctly aligned on the approach path.
