I would like to think that AH know definitively that the problem is confined to a single type of MRB arrangement i.e. the one that failed but can't say so for legal reasons. Hopefully all will be made clear by a future report. The corner they have backed themselves into is that previous statements, especially the suspension rod debacle, has undermined credibility somewhat. So trust has been eroded. This cloud is going to hang over the type unless and until the AIBN are able to give us something more definitive
