I'm glad this has finally come out,- that TAIC were idiots. The job they did on this investigation was below poor yet we rely on them to come up with plausible conclusions based on fact so the rest of the industry can learn and hopefully related tragedies can be avoided.
TAIC showed up, did a quick weight and balance found it was out, default determined that was the cause, put everything in big hole and buggered off out of there because it was pissing down with rain and they had earthquake damage to deal with back home.
For the next year or what ever they maintained this mindset until it was published in the report as the cause of the accident, with minimal consultation with the rest of the bewildered industry and overwhelming evidence on the contrary at their disposal.
I agree that an out of limit C of G would not help the recovery, but most importantly - WHAT CAUSED THE UPSET ?
Unfortunately now we will probably never know. For the good of the industry it was the job of TAIC to find out. They didn't do their job.
