Spinwing,
You are assuming the problem is with the aircraft.
You've never worked at Gulf Helis have you. I have. Was good for a while, then the MD was replaced, then the Chief Eng (has been replaced once or twice since I left too), then things started to go rapidly downhill. We (the expat AME's) basically all left within a few months of each other so that we wouldn't be there when the accidents started happening.
Guess what, they are now happening. Surprise sur-freakin-prise.
How about Qatar CAA allowing other operators to come in and operate there so that at least the people going offshore have a choice, instead of being forced to use the only company allowed to fly in Qatar.
Now lets wait and see if Agusta come out with an Alert for us, and if not, lets see what the interim or final report has to say.
I can't think of any helicopter that will keep a TGB in place with one tailrotor blade missing, so the strength of the fin is not an issue. The issue is why did the blade depart. Lets try to focus on that shall we???
