Haven’t read the entire thing but have made a start.
In the original report, the CVR/FDR supposedly weren’t recovered because the CVR was only going to have the last 30 mins... not enough to cover when the PNR fuel calculations and discussions should have occurred.
Interestingly, the new report shows that the CVR was actually a newer model which held over 2 hours of audio.
Apparently the serial number in the maintenance documentation matched the CVR.
So what was the reason it wasn’t pulled the first time? Was it political pressure to not have it removed (involving strong ties to an ex-politician), or was it a case of the operator deliberately didn’t supply the correct paperwork with regard to the CVR model fitted?
I want to know why the ATSB didn’t know it was a two hour CVR.
