The damaged black box from doomed EgyptAir flight MS804 has been successfully repaired, allowing investigators to analyse data which may explaining why the jet crashed.

The cockpit voice recorder is set to be worked on "within hours", officials said.

The flight data recorders arrived in Paris from Cairo on Monday to remove salt deposits.

They will be sent back to a laboratory in Cairo to analyse the data once the repairs are completed.

The development came as French prosecutors opened a manslaughter inquiry into the air disaster , saying there has been 'no evidence of terrorism ' so far.

The Airbus A320 went down into the eastern Mediterranean Sea en route from Paris to Cairo when all 66 people on board were killed last month.

The Paris prosecutor's office yesterday said it was opening a "full investigation into involuntary homicide".

Asked if the prosecutor was looking into terrorism at this stage, an official said: "No".

The cause of the crash remains unknown.

It comes as damaged memory chips from the plane's black boxes were flown to France for repairs, a source on the investigation committee said.

Egyptian investigators have been trying for days to repair the memory chips, which would allow them to begin transcribing and analysing the recordings and data in pursuit of insight into what caused the crash.

The investigation committee source said the memory chips were accompanied by investigators to France, where they will remove sea salt deposits from the chips at a lab belonging to France's BEA air accident investigation agency.

The chips will be returned to Cairo for analysis once they are repaired.

Debris from the jet has been brought to Cairo airport where investigators will try to reassemble part of the plane's frame in search of additional clues that may help explain crash, the source added.
