Comoran authorities, meanwhile, are still investigating the cause of the June 30 crash. A 12-year-old girl is the only known survivor out of 153 people aboard.
Capt. Marc Reina tells The Associated Press from the French island of Reunion that his crew has found where the black boxes lie beneath the Indian Ocean and mapped the area off the Comoran coast.
He said Thursday that underwater robots should begin operating in August to retrieve the black boxes, which lie too deep for divers to reach.
The plane's cockpit voice and flight data recorders could help explain why it crashed as it tried to land in heavy winds.
