Investigators of the crashed EgyptAir flight MS804 will hand over the recently retrieved black box flight recorders to the Central Department for Aircraft Accident at the Egyptian Ministry of Civil Aviation for further inspection.

The ministry will try to unload data from the flight recorders.

Operated by EgyptAir, the Cairo-bound Airbus A320 flight MS804 crashed in the Mediterranean Sea last month, killing all the 66 people on board.

"The automated messages point towards a sign of smoke emanated in the cabin and a fault in the flight control unit."

The technical investigation committee for the A320 flight MS804 has received the cockpit voice recorder (CVR) and the flight data recorder (FDR) after being retrieved from the location of the wreckage.

Egypt’s Ministry of Civil Aviation noted that the analysis of the black boxes data could take several weeks to complete, provided the memory units at both recorders are in good condition.

After analysis, data unloading process will begin at the labs of the Central Department for Aircraft Investigation.

The ministry also said that if there is a minor damage at both or either of the black box flight recorders, the damage will be repaired locally.

However, in case of major damage, repair process will be performed abroad under the supervision of the investigation committee.

France’s aviation safety agency has stated that the crashed plane transmitted automated messages minutes before it vanished, reported the Guardian.

The automated messages point towards a sign of smoke emanated in the cabin and a fault in the flight control unit.

Apart from seven crew and three security personnel, 30 passengers on the plane were Egyptians, 15 French citizens, two Iraqis, two Canadians, and citizens from Algeria, Belgium, Chad, Portugal, Saudi Arabia, Sudan and the UK.
