EgyptAir Flight 804

EgyptAir Flight 804 was a regularly scheduled international passenger flight from Paris Charles de Gaulle Airport to Cairo International Airport, operated by EgyptAir. On 19 May 2016 at 02:33 Egypt Standard Time (UTC+2), the Airbus A320 crashed into the Mediterranean Sea, killing all 66 occupants on board.

No mayday call was received by air traffic control, although signals that smoke had been detected in one of the aircraft's lavatories and in the avionics bay were automatically transmitted via ACARS shortly before the aircraft disappeared from radar. The last communications from the aircraft prior to its submersion were two transmissions from its emergency locator transmitter that were received by the International Cospas-Sarsat Programme. Debris from the aircraft was found in the Mediterranean Sea approximately 290 km (180 mi) north of Alexandria. Nearly four weeks after the crash, several main sections of wreckage were identified on the seabed, and both flight recorders were recovered in a multinational search and recovery operation. On 29 June, Egyptian officials announced that the flight data recorder data indicated smoke in the aircraft, and that soot plus damage from high temperatures was found on some of the wreckage from the front section of the aircraft.

On 30 October 2024, two reports were released with conflicting conclusions about the cause of the crash. Egypt's Civil Aviation Authority, which headed the investigation, concluded that the crash was the result of an explosion occurring in the galley near the cockpit, which was rapidly engulfed by smoke and fire, exacerbated by oxygen flow being present. The French investigative agency BEA disagreed with this conclusion, instead finding that the fire was most likely a result of a fault in the oxygen mask.
