Checkboard - that's only an initial investigation notification and not a Preliminary Report which normally follows the initial investigation. Then, after usually a loooong time, comes the Final Report.
HH - An ATSB source tells me it's in water at less than 500 mtrs and they (ATSB) have already located the wreckage and attached a line to it to facilitate later retrieval of the FDR and CVR.
CarR - close to the money from my same source.
