The accident is now included in the BEA's summary of incidents and accidents in week 52 of 2015 (only on the French-language site):

It lists SOB as only 5, with 8 fatalities and 9 serious injuries. Presumably the 5 on board would be flight and cabin crew: all uninjured (?). Damage to the airframe "substantial". They attribute the information to the local authorities (of the Democratic Republic of the Congo).
One imagines the landing weight would have been very low, unless they were tankering fuel. Does anyone know if fuel is available at Mbuji-Mayi?
