On Jan 10th 2017 Mozambique's Civil Aviation Authority reported in a press conference in Maputo that they concluded the radome most probably failed as result of a structural failure caused by air flow pressure, contributing factors probably were a defective installation of the radome and inspection of the ribs. A foreign object damage was ruled out. The CAA added, that the radome had been purchased second hand through an American company supplying aircraft parts and components, the radome was installed on the aircraft during major maintenance in South Africa on Jun 27th 2016.
