I've had a couple of bizarre, and catastrophic, failures while at
cruise altitude in the BAW 763, which has the RR engines. The
only clue I can come up with is the N2 and N3 engine stages
(only the RR has 3 stages) ALWAYS go into the yellow when I
take off, and seem to stay that way thru much of climb. What I
was thinking was that this stress eventually caused an engine
failure but I'm not sure.

At the very least it seems like one should be able to keep every
thing in the white. Does anyone have any advise or help on that,
or just other experience with the RR model??

Thanks,

Jack
