And is the CVR/ADR now fitted?
Don't know, but both ROs addressed (dismissed) the issue by claiming the requirement would be satisfied when HUMS was fitted in 1997/98.
Perhaps someone could confirm HUMS is indeed crashworthy to the same degree a "normal" ADR/CVR is? My admittedly limited recollection is that HUMS was not designed to be a combined ADR/CVR. Perhaps that intention changed.
