The Minister of Information in Eastern Lakes State says there are two main steps left to establish the cause of the Yirol plane crash.
The passenger plane crashed into Lake Yirol on Sunday, killing 20 passengers.
Among the dead were two children and the Bishop of the ECS Yirol Diocese, Simon Adut.
Three passengers: a 5-year-old girl, a 40-year-old man and an Italian doctor survived the crash.
Eastern Lakes Information Minister Taban Abel said a team that was sent to the area found the black box of the plane and took it to Juba.
“Phase one is the black box which we retrieved and we sent to Juba. Phase two is the survivors have to give their account of what happened. Luckily we have two adults who can actually tell us what has happened,” he said.
“Number three now is the analysis of what has been recorded by the black box. The three will culminate into the final outcome.”
Meanwhile, the chairperson of information committee at the transitional legislature said the committee on transport has already summoned the undersecretary of the ministry of transport to explain the matter.
“We need to find out who are the people involved because almost in some of the plane crash, it is something to do with having many people on board,” said Paul Yoane.
The Czech-built twin turbo-prop was being operated by Ukrainian carrier Slaver Kompani on behalf of South Sudan-based South West Aviation.
According to Flight Global, the plane was first flown in 1984.
