Agreed and worth noting that some 18 months ago the AAIB recommended that the regulatory authorities consider, as phil gollin says: "undertaking such research and then applying it to ALL airframe and engine combinations."
That ball has been in the regulators court for 18 months now, and it is out of order to blame the AAIB if the regulators haven't done anything with it.
