My point of view has always been, I would rather fly the EC225 with one known problem, that we can monitor/manage, than the Tiger. That said the Tiger (AS332L) is a reliable old girl and we know her intimately, both flying and maintaining it, I just prefer the 225.
From an engineering point of view EC can now make the shaft fail on command, so they know the problem and can then design a fix. That gives me comfort that they have found the problem and also have had their data ratified by several outside agencies.
In short the answer to your question is, Yes I would be happy to fly the 225 with the remedial actions going on. That and I know our engineers will go above and beyond the EC directive to satisfy themselves the aircraft is serviceable. The only question is how long it will take to get them going again.
