A Let L-410 aircraft crashed near Sougu‚ta, Kindia, Guinea, resulting in the fatalities of all four crew members. The flight departed Conakry at 10:01 and was scheduled to arrive at L‚ro at 11:41. At 10:11, the flight switched to the Roberts FIR controller, subsequently reducing altitude to 3500 feet. The aircraft impacted a tree covered hillside at an elevation of 2626 feet, likely due to poor visibility conditions. Probable causes included reduced visibility, mountainous terrain, conflicting traffic coordination between the Conakry Tower and Roberts FIR controllers, and crew obstinacy in dealing with adverse weather conditions. The flight crew lacked knowledge of the weather conditions, leading to poor decision-making at low altitude. Furthermore, the lack of a weather file contributed to the problem.A Let L-410 aircraft crashed near Sougu‚ta, Kindia, Guinea, resulting in the fatalities of all four crew members.
