If the factory was the original source of the 'information' that you have, please post it here, because then it would be gospel.
If it didn't come from the factory officially then I stand by my previous post and you may be opening yourself up for action.
What you've suggested is that all Airvan operators need to effectively ground their aircraft immediately because a condition exists where the aircraft may crash / fall out of the sky, but the ATSB knows about it? Surely CASA would distribute such information?
As for the wreckage answering a lot of questions, that is indeed true, however don't hold your breath if a wheel has been found because there may be very little left of it.
