The flight data recorders from an EgyptAir airliner that crashed in the Mediterranean last month are expected to continue emitting signals until 24 June, according to an official Egyptian committee investigating the crash on Monday.

"According to the information provided by the manufacturers of the plane recorders, it is expected [that] the continuation of the singles emitted by the plane recorders [will last] until the 24th of this month," reads a statement.

The EgyptAir Airbus A320 plane crashed into the Mediterranean, presumably killing all 66 people on board, during a 19 May flight from Paris to Cairo after disappearing from radar screens.

Two French vessels have been searching the Mediterranean to locate the exact position of the black boxes as the reasons behind the crash haven't been determined yet.

The civil aviation ministry also confirmed that the plane turned 360 degrees before it disappeared from radar screens.

"The radar photos which were delivered to the investigation committee affiliated with the Egyptian military shows that before the crash happened that the plane turned left then right in a full cycle," the statement read.

"This information comes in accordance with the photos which were transmitted from Greek and English radars," the statement said. "But we can't rely on this information and separating it from the context of the investigations," the statement said.

Greek Defence Minister Panos Kammenos had said the aircraft "made swerves and a descent" after it entered Cairo FIR (flight information region), "90 degrees left and then 360 degrees to the right."

Last month, Al-Ahram Arabic daily newspaper published a document from the Aircraft Communication Addressing and Reporting System (ACARS), which showed that the doomed Airbus 320 jet transmitted "11 electronic messages" starting 2109 GMT on 18 May.

The first two messages indicated that the engines were functioning properly.

The third message, which was sent at 0026 GMT on 19 May around four minutes before the plane vanished from radar, indicated a rise in the temperature of the cockpit's right-side window.

The plane then continued to send messages for three more minutes before dropping off radar screens.

Earlier this month, a French ship picked up signals from deep in the Mediterranean Sea from what is believed to be the black boxes from EgyptAir's plane as recordings on the black boxes could help investigators determine the cause of the crash.
