Please correct me if I'm wrong (and I'm certain you will), but doesn't this engine power some aircraft other than the NH 90. I seem to recall that the Brits selected this engine for some of their medium/heavy aircraft too.
Does anyone here know who called for the Ausstralian fleet grounding? Was it Rolls Royce/Turbomeca or was it the ADF? Has any other operator also grounded their fleet?
