The Egyptian Aircraft Accident Investigation Committee is running electrical tests on the recovered black box recorders of crashed EgyptAir Flight MS804, the committee said in a statement on Sunday.
Under the supervision of Egyptian investigators and a certified French expert in flight recorders, the cockpit voice recorder (CVR) and the flight data recorder (FDR) were first put through an eight-hour drying process on Saturday at a military technical research centre, Xinhua news agency reported.
The data and information in both recorders, if they are sound, will be extracted after the ongoing electrical tests, according to the statement.
On Wednesday, the investigation committee said the hired vessel, Lethbridge John, located several wreckage sites of the crashed plane in the Mediterranean.
A day later, the committee announced the vessel found the crashed jet's CVR although it was damaged.
EgyptAir Flight MS804, an Airbus A320, went off radar en route from Paris to Cairo on May 19, with 66 people on board, including 30 Egyptians and 15 French people.
