EgyptAir Flight 804 Data Recorder Indicates Smoke in Bathroom, Avionics Bay

Information pulled from EgyptAir Flight 804's data recorder suggests smoke may have been detected in the lavatory and avionics bay in the moments before the doomed flight plunged into the Mediterranean Sea on May 19, the Egyptian government said today.

Some of the wreckage, recovered from the front section of the aircraft, showed signs of high temperature damage and soot, the Egyptian Aircraft Accident Investigation Committee reported.

Experts say the smoke alerts indicate that the plane, an Airbus A320 carrying 66 from Paris' Charles de Gaulle Airport to Cairo International, likely suffered an electrical fire.

According to Egyptian investigators, preliminary data shows that the flight data recorder abruptly cuts off at an altitude of 37,000 feet.

Today's information is consistent with data from the plane's ACARS (Aircraft Communications Addressing and Reporting System), leaked to the Aviation Herald late last month.

At the time, an A320 chief avionics mechanic for a major U.S. airline said that the ACARS data suggests the window heater computer in the avionics compartment may have malfunctioned, which could have eventually sparked a total electrical failure on the jet.
