Circumstances:
The twin engine airplane was carrying two technicians and two pilots bound for a mine field located near Lero, Kankan. It made an intermediate stop at Conakry on a flight from Sal, Cape Verde. En route, the crew encountered poor weather conditions with low clouds and fog when the airplane impacted the slope of a mountain. The airplane disintegrated on impact and all four occupants were killed.
