EgyptAir chairman Safwat Musallam did not name the French and Italian companies involved but told a news conference they were able to carry out searches at a depth of 3,000 meters.
Two French diplomatic sources said Egyptian authorities and France's BEA air accident investigation agency were finalizing a contract with two French companies, Mauritius-based Deep Ocean Search and Alseamar.
"The objective is to go extremely quickly so they can find the boxes that are probably in very deep waters," said one source.
The source said the costs of the contract would be shared between France and Egypt. Neither source was aware of talks with the Italian company.

Because of the depth of water in area you will not likely be able to hear the sonar pinger on the surface because of
There are thermoclines (layers of water of differing temperature) and haloclines (layers of water with different
salinity) which interfere with sound propagation
You would need a towed hydrophone array lowered near the bottom to pick up signals from the pinger which has range of
only few miles
Airbus has detected signals from the Mediterranean Sea where EgyptAir Flight 804 crashed last week, Egypt's state-run Al Ahram news agency reported Thursday. The signals were emitted by the plane's emergency locator transmitter, a device that can manually or automatically activate at impact and will usually send a distress signal.
Doubts have been cast on whether an ELT on flight 804 could have survived or sent signals from underwater. John Cox, a former A320 pilot and chief executive of Washington-based Safety Operating Systems, expressed caution about the reported signal from the sunken wreckage.
“There is a low likelihood the ELT would survive, and radio doesn’t work as well as acoustic signals underwater,” he said.
