OK Flytest, this is the last snag we had, just after a few days routine scheduled maintenance operation:we air tested our bird and our HUMS completly failed the symptoms were;
1/ No record at all on the data card (we tried 2 different)
2/ "MDR" light on at all times(normal because of 1)
3/ The red light on on the "IMP"(normal, because of 1 and 2)
4/ No "HUMS" warning light on the caption advisory panel....(not normal, I think)
This came after a slow progressivly degrading situation along with passing weeks, I believe our HUMS just gave up its fight with many thousand greemlins.
I must admit such a sophisticated device requires a very comprehensive training to keep it operating properly, as well as a good deal of experience.
By the way did you get my mail ?
Rgds.
