The black box had been retrieved from the bottom of the Mediterranean after the Airbus A320 with 66 people on board plunged into the sea on 19 May while heading to Cairo from Paris.
It had recorded the data of flight MS804 from its departure until it “stopped at an altitude of 37,000 feet [11,250 metres]”, the committee said in a statement on Wednesday.
“Recorded data is showing a consistency with Acars [aircraft communications addressing and reporting system] messages of lavatory smoke and avionics smoke,” it said, two days after the damaged recorder was repaired in France.
Investigators had previously announced that the plane’s automated Acars sent signals indicating smoke alarms on board the plane before it went down.
“Parts of the front section of the aircraft showed signs of high temperature damage and soot,” the committee statement added.
The repair work of the cockpit voice recorder, the second black box, had also begun.
The plane was carrying 40 Egyptians, 15 French, two Iraqis, two Canadians and one passenger each from Algeria, Belgium, Britain, Chad, Portugal, Saudi Arabia and Sudan.
