Or seat pin failing...........?
Very sad, anyway you look at it...
I think, from what I know, this is exactly what the ATSB should look at first. Will save a lot of time and trouble.
Nothing more to say, so you can read between the lines.
So sad and likely to be so avoidable.
I did know the pilot as did a few pruners so I do not write this lightly.
TBM Legend....could you please contact me somehow. I am easy to find.
