Description

A Let L-410UVP-E3, operated by Doren Air Congo, crashed in the Kahuzi-Biega National Park, some 28 km from the destination, Bukavu-Kavumu Airport, Democratic Republic of the Congo. The two crew members and two passengers were killed. The aircraft was operated by Doren Air Congo on behalf of a freight agency called Soci‚t‚ Agefreco and carried 800 kg of supplies. Preliminary conclusions: 1. A human error; 2. Non-compliance with meteorological alerts; 3. Non-compliance with the specified flight altitude in this mountainous area because, in the case of dry fog during the dry season (from the beginning of June to the end of August each year), visibility can be zero in this area. Contributing Factors 1. Sudden break in communication between the controller and the pilot just after the first contact was announced: “I am 15 nautical miles from your station (Airport) and I estimate arrival at 13:42 TU.” It was his first contact during his flight from KALIMA, but also his last contact and his final flight. 2. Likely insufficient fuel; 3. Work overload of the crew members.
