Yes Flytest, you have put the finger on it, the HUMS system set up should go along with a real expertise and an open minded maintenance policy...but this is another story
It is one of the aspects of a silent revolution our corporation has to chalange, of wich the "jurassic park thinkers" will not survive.
The concern is: how much arm can still they cause untill then ?
.... but here the slope becomes a bit slippery
Glad to have talk to you Flytest.
