Good on the RA-Aus for what they have just done.
Aircraft is lost on 5/7/14, recovered a week or so later, the wreckage investigated and the following Service Bulletin has just been released:

Nobody had definitively said that this is what happened on the crashed aircraft, however anecdotal evidence suggests that the the release of this SB is in response to this crash.
Joining the dots, elevator control is lost and the aircraft nose dives whilst losing major components on the way down.
