Accident Details
A twin-engine airplane, transporting two technicians and two pilots to a mine field located near Lero, Kankan, crashed after encountering poor weather conditions. The flight originated from Sal, Cape Verde, with an intermediate stop at Conakry, Guinea. En route, the crew faced low clouds and fog, leading to the aircraft impacting a mountain slope. The airplane disintegrated upon impact, resulting in the deaths of all four occupants.
Official Findings
The investigation identified several factors. Environmental conditions included reduced visibility and a low cloud ceiling. Mountainous terrain was also a factor. There was a contradiction in traffic coordination between Conakry Tower and Roberts FIR controllers. The crew demonstrated obstinacy in dealing with bad weather while flying at low altitude.
Contributing factors involved the flight crew's failure to retrieve the weather file, leading to a lack of knowledge of the prevailing weather en route. The captain made poor decisions regarding the weather. Additionally, there was a low level of visual flight in poor weather at low altitude.
