Hello All
David, the quote "structural, right wing failed???" is not correct.
I was at the accident site today and I can let you know that the starboard wing remained solidly attached at the wing root & via the two upper & lower hinge pin points.
The port wing however showed a degree of structural damage, some of which was in the region of the upper & lower hinge pin points (the cause of which is still under investigation by the ATSB).
Condolences to the Pilots family & friends.
