  • BEA PRESS RELEASE – 19 MAI 2016 18H30

    Following the accident to an Airbus A320, registered SU-GCC, off the Egyptian coast, the Egyptian civil aviation authorities have informed the BEA of the initiation of a safety Investigation.

    The aeroplane, operated by Egyptair, was flying the Paris (France) – Cairo (Egypt) route as flight MS804.

    The Airbus A320 had taken off from Paris-Charles de Gaulle airport on Wednesday 18 May 2016 at around 23 h.

    In accordance with international provisions the BEA, representing the State of Design of the aeroplane, is participating in the investigation.

    A team of three BEA investigators, accompanied by a technical advisor from Airbus is travelling to Egypt in the next few hours.

    The BEA will be able to advise the Egyptian authorities on the organisation of underwater sea-search operations with a view to locating the aeroplane and the flight recorders.

  • Undersea search operations to locate the wreckage of the Airbus A320 registered SU-GCC, flight MS 804, off the coast of Egypt

    A campaign of undersea searches will begin in the next few days with the arrival in the accident area of the French Navy hydrographic ship the "Laplace". This ship is equipped with three DETECTOR 600s, belonging to the French company Alseamer, a submersible system to listen for and localize the signal from the flight recorders' locator beacons.

    The "Laplace" is sailing today from Porto Vecchio bound for the search area, off the Egyptian coast, with two BEA investigators on board. 

    Discussions are continuing today to complete this operation with a second ship equipped with a remotely operated exploration vehicle, along with salvage equipment appropriate for the great depths in this search area, estimated at 3,000 metres.

    The Egyptian authorities, who are leading the investigation, are co-ordinating these undersea search operations with technical assistance from the BEA.

  • The Egyptian authorities yesterday, 27 May, signed an memorandum of understanding with the international company Deep Ocean Search (DOS) to complete the team searching to recover the two flight recorders.

    Progress report n°3 published by the Egyptian authorities:

    "CAIRO - 27 May 2016

    The Ministry of Civil Aviation signed a memorandum of understanding today with the international company Deep Ocean Search “DOS”to carry out the search and retrieval process of the two data recorders of the A320, downed last week in the Mediterranean. 

    DOS is one of the best companies in this field; thatuses the most advanced technology in reading the signals of the two boxes in addition to its ability to conduct extensive sonar scan for the search area. 

    It is worth mentioning that the French vessel used in the search process is equipped with Alseamar, which is considered as one of the best equipment used in this field.

    On the other hand, the investigation committee has started studying the information received from theGreek air traffic control about the accident; more information of the records of the radar that had followed the path of the plane before the accident, is expected to be also received."

    Review of situation on 6 july 2018 18H15

    Following the accident on 19 May 2016 over the Mediterranean Sea involving an Airbus A320 registered SU-GCC operated by EgyptAir, a safety investigation was immediately opened. In compliance with the international texts in force, as the accident occurred in international waters, Egypt, as the State of Registry and State of the Operator of the aeroplane, is in charge of carrying out this investigation. The BEA appointed an Accredited Representative to represent France as the State of Design of the aeroplane, assisted by technical advisers from the aircraft manufacturer, Airbus. The NTSB (1) also appointed an Accredited Representative to represent the United States as the State of Manufacture of the engine.

    France contributed to the safety investigation from the very outset. Initially, the BEA’s work consisted in acting as advisor to its Egyptian counterpart and then in participating in sea search operations for the aircraft wreckage. At the same time, the three States collaborated in collecting and analysing the first elements available - in particular the ACARS (2) messages.

    Once the wreckage had been found, the debris was inspected and the flight recorders were located, retrieved and immediately sent to Cairo in order to start the initial work to recover and read the data. These operations, collectively decided on and carried out by the Egyptian, American and French specialists, did not succeed in reading the recorded data due to the severe damage to the data media. Advanced repair work was then necessary and the BEA was asked to carry it out in its laboratory in France.

    The work on the flight recorders was carried out under the authority of the Egyptian Investigator In Charge, on the BEA premises, and at the beginning of July 2016 the data from the two flight recorders was extracted, read and decoded.

    During this work, the Egyptian authorities published the following elements about the accident:

    - The flight recorders stopped operating while the aircraft was in cruise at an altitude of 37,000 feet;

    - The aircraft systems sent ACARS messages indicating the presence of smoke in toilets and the avionics bay;

    - The data from the data recorder confirms these messages;

    - The playback of the cockpit voice recorder reveals, in particular, that the crew mentioned the existence of a fire on board;

    - Several pieces of debris were retrieved from the accident site. Some of these had signs of having been subject to high temperatures, and traces of soot.

    Once the data from the flight recorders had been retrieved, the Egyptian authorities continued their work in Egypt.

    In addition, the BEA had collected the following elements:

    - A signal from an emergency locator transmitter was sent at 00:37 (source CNES (3) ) i.e. around eight minutes after the transmission of the last ACARS message;

    - Data from a Greek primary radar (sent by the Greek authorities to the BEA) shows that the aeroplane had descended in a turn until collision with the surface of the water.

    Based on these elements, the BEA considers that the most likely hypothesis is that a fire broke out in the cockpit while the aeroplane was flying at its cruise altitude and that the fire spread rapidly resulting in the loss of control of the aeroplane.

    For its part, the BEA’s Egyptian counterpart announced in December 2016, the discovery of traces of explosive on human remains. It stated that, in accordance with Egyptian legislation, this finding led it to transfer the file to the Egyptian Attorney General who would from now on be responsible for carrying out the investigation.

    The BEA’s proposals concerning further work on the debris and recorded data were not, as far as the BEA knows, followed up. The technical elements of the investigation already collected by Egypt, including those provided by the BEA, are protected by the Egyptian judicial investigation.

    In an effort to continue the safety investigation mission, the BEA asked to meet the Egyptian Attorney General. This took place at the end of May 2018. In this meeting, the Egyptian authorities explained that as it had been determined that there had been a malicious act, the investigation now fell within the sole jurisdiction of the judicial authorities.

    The BEA’s Egyptian counterpart did not publish the final report which would have allowed the BEA to set out its differences of opinion as authorized by the international provisions.

    The BEA considers that it is necessary to have this final report in order to have the possibility of understanding the cause of the accident and to provide the aviation community with the safety lessons which could prevent future accidents.

    As mentioned above, the BEA considers that the most likely hypothesis is the rapid spread of a fire and would like investigations into this hypothesis to be continued in the interests of aviation safety.

    The BEA is ready to continue its collaboration with its Egyptian counterpart should the latter restart the safety investigation into this accident.
