What happened
A flight departing from Yaoundé at 16:58 local time was scheduled to arrive in Douala by 17:30. During the transit, the four-engine aircraft encountered marginal weather conditions while cruising. The plane struck a slope on Mount Koupé, which stands at an elevation of 2,064 meters, approximately 80 km north of its intended destination.
Following the failure of the flight to reach Douala, search and rescue operations were initiated. These efforts were eventually halted after several days when no evidence of the wreckage or the 12 fatalities could be located. The debris was not discovered until 19 February 1956, when hikers located the site within a heavily forested area on the mountain.
Findings
Investigators concluded that the accident was likely the result of controlled flight into terrain. While the impact occurred significantly north of the intended flight path between Yaoundé and Douala, official inquiries could not establish why the aircraft had deviated from its course or identify the specific reason for the collision.
