The flight data recorder of the crashed EgyptAir flight MS804 has been fixed, Egyptian officials said, as French authorities opened a manslaughter investigation into the tragedy.
The airliner’s two recorders — one containing flight data and the other voice recordings from the cockpit — were handed to French investigators after being recovered from the wreckage in the Mediterranean.
Because they were damaged, Egyptian investigators could not access their contents. The repaired flight data recorder will now be sent back to investigators in Cairo.
Work is continuing to retrieve the voice recordings from the other “black box”.
After the 19 May crash, Paris prosecutors opened a preliminary investigation, a routine step as French citizens were among the 66 dead.
French judges launched a manslaughter investigation on Monday based on the prosecutors’ findings and evidence gathered so far.
Agnes Thibault-Lecuivre, a spokeswoman for the prosecutors’ office, said it was being treated “as a criminal case, not a terrorism investigation”.
The black boxes were sent to the French Investigation and Analysis Bureau, which retrieved data from the recorders carried on Air France flight 447 after it crashed in the Atlantic on a flight from Rio de Janeiro to Paris in 2009.
The EgyptAir plane emitted automated signals indicating smoke in the cabin and a fault in the flight control unit minutes before plunging into the Mediterranean, France’s aviation safety agency said.
The Airbus-A320 appeared to spin out of control, veering 90 degrees to the left and then making a 360-degree turn to the right before it hit the sea.
The crash followed the bombing of a Russian airliner over the Egyptian Sinai, where Isil and other terrorist groups operate. All 224 people on board the Russian plane were killed.
