Circumstances:
During the night of 4th May 2007, the B737-800, registration 5Y-KYA, operating as flight KQA507 from Abidjan international Airport, Ivory Coast, to the Jomo Kenyatta Airport in Nairobi (Kenya), made a scheduled stop-over at the Douala international Airport. The weather was stormy. Shortly after takeoff at about 1,000 feet, the aircraft entered into a slow right roll that increased continuously and eventually ended up in a spiral dive. On the 5th May 2007 at approximately 0008LT, the airplane crashed in a mangrove swamp located south-southeast of Douala. All 114 occupants on board were killed and the airplane was completely destroyed.
Probable cause:
The airplane crashed after loss of control by the crew as a result of spatial disorientation (non recognized or subtle type transitioning to recognized spatial disorientation), after a long slow roll, during which no instrument scanning was done, and in the absence of external visual references in a dark night. Inadequate operational control, lack of crew coordination, coupled with the non-adherence to procedures of flight monitoring, confusion in the utilization of the AP, have also contributed to cause this situation.
