CAIRO • A French navy vessel equipped with deep-water listening devices has detected signals from one of the black boxes of the EgyptAir plane that crashed in the Mediterranean, investigators said yesterday.
The flight recorders could contain crucial information to help solve the mystery of why the Airbus A320 plunged into the sea with 66 people on board en route from Paris to Cairo on May 19.
The signals were picked up by the French survey ship Laplace, which is using acoustic detection systems to listen for the "pings" emitted by the flight recorders, France's aviation safety agency BEA said. "The detection of this signal is a first step," said BEA official Remi Jouty.
Egypt's Ministry of Civil Aviation had announced the potential breakthrough earlier, saying the signals were "assumed to be from one of the data recorders".
Some of the wreckage has already been pulled from the Mediterranean along with passenger belongings. No survivors have been found.
Another vessel sent by Deep Ocean Search, a private company hired to help find the black boxes, is on its way to the area carrying a ship with a robot capable of diving up to 3,000m to retrieve the recorders.
The ship is due to arrive at the site within a week, the Egyptian ministry said.
"Extensive search efforts are being carried out to locate the two data recorders in preparation for their retrieval," the ministry said.
The black boxes have enough battery power to emit signals for four or five weeks.
The Laplace is equipped with three devices capable of picking up the "pings" from the black boxes up to 5km away.
Investigators have said it is too soon to determine what caused the disaster, although a terror attack has not been ruled out.
