I think it would be a mistake to assume that the problem stemmed from an engine problem. The only engine problem was a mismatch in power settings. Personally I think we may find that the root cause of the accident caused both the engine problem and the control problem. There are some possible scenarios but I am not going to speculate at this stage.
HUMS on the 225 is called M'ARMS and yes its a later design than the EuroARMS on the L2.
sox - when I said the AAIB I did of course mean the Dutch version but not knowing what they were called, AAIB was as close as I could get! Sorry about that!
