"Le chassis" (in the French text) may refer to the 'mounting rack', not to the FDR unit itself.
It's what I was afraid of... the recorder(s) being ripped from their mounting racks (not necessarily designed to the same crash-resistant standards as the recorders themselves), and making their own way to the sea bottom, and getting buried in the silt....
Good luck, guys...
Edit: Ignore, please. I've now seen the photos, and that's obviously the recorder unit, not the 'mounting rack'. Not sure whether the photos show the CVR or the FDR, though.
