Lots of problems with Tiger contract obligations not being met. Consequently the government stopped payment and effectively told AA to provide two airframes for the newly trained rotary wing pilots to keep their hours up. One of the complications with introducing new platforms/airframes is that you have to train personnel in all aspects of their operation so everything "hopefully" falls in place for the planned timelines. There is quite a long lead time for all this which starts from before recruiting.It's a very long list. If you really want to know just google it. Airframe, engines, the sight sytem and on and on. The flight our cost is about double that promised. Eurocopter even supplied and payed for training helicopters so pilots could get flight time. They wouldn't do that if it wasn't their fault.
Since the transfer of rotary wing aviation to the Army from the Air Force there has been a continual bleeding of particularly maintenance personnel and a definite lack of airmanship which regularly shows it's ugly head. One of the primary reasons for this is a very small gene pool of army aviators resulting in a culture which has a habit of losing the primary focus of safety during peacetime ops. Too many examples over the years shows this. One which stands out is that when I was working as a maintainer, we received an official post Board of Inquiry briefing explaining why a helo crashed with fatal results. We understood why from an engineering perspective as it was effectively pilot error resulting from a bad culture. The pilots received the same briefing prior to us and when told they were a bunch of cowboys nearly resulted in fisticuffs. And that is the tip of the iceberg in Army Aviation.
Yes, Tiger is a POS and so is MRH. Design a northern hemisphere cold weather aircraft and use it in hot and humid conditions and sometimes things just don't work. One of the questions asked of MRH was where is the airconditioning system? The reply was along the lines of, why do you need that in Oz. FFS, they had to buy an airconditioning system for the thing. The Army pilots wanted Blackhawks replaced with Blackhawks but they ended up with MRH. Meanwhile the RAN is quietly parking theirs up and switching to the Seahawk.
On the other hand during the 60's & 70's, French aircraft sold themselves in Africa and the Middle East. Think Mirage F1 and Aloutte II & III.
