The BEA (the French air accident investigation office) reports it has found the shell of AF447's flight data recorder, but not the crash survivable memory unit that stores the data.
It is still unclear how much of a set back the absence of the CSMU (at right in second picture; marked as "enregistreur de vol" and indicated as "module memoir") this represents.
The FDR casing (marked as: "chassis" above) was found on the first dive of the Remora 6000 unmanned, underwater vehicle, which operated for 12 hours. Other aircraft debris was in the area.
The BEA says a second Remora 6000 dive is underway.
The Remora 6000 is being operated by the search and recovery team on the Ile de Sein.
The search continues to locate the CSMU and other elements of the Airbus A330-200 belonging to the Air France flight that crashed June 1, 2009 on its flight from Rio de Janeiro to Paris.
