A report which should be circulated to all involved in maintenance. And not just in Australia.
I'm sure that the use of the wrong procedure and the wrong jointing compound was only done with the best intentions. But it was wrong - and it seems that this was not an isolated mistake.
As part of a wideranging review conducted during this investigation, it was discovered that many more helicopters had drive systems similarly assembled (using the wrong jointing compound and against Robinson's instructions) - across Australia.
Why ? Isn't the correct compound available in Australia ? If it isn't, surely Robinson would have supplied it on demand ?
Is this another case of short-cut maintenance ? How did the "recipe" spread so widely ?
And what do the insurers and the bereaved have to say ?
