French officials say investigators are ready to begin a fourth search for the wreckage of an Air France jet that crashed off Brazil's coast two years ago.
The June 2009 crash of Air France Flight 447 killed all 228 people on board.
The jet went down as it hit a high-altitude thunderstorm while en route to Paris from Rio de Janeiro.
Investigators are searching for the jet's data-filled "black boxes" to determine what caused the crash.
Martine del Bono is a spokeswoman with the French accident investigation agency overseeing the search. He said that the search will begin late Monday or early Tuesday and will run until July.
