I'm not sure if you are refering to the machines here, but if so I think you need to think about the following:
R22/44's have been flying many thousands of hours in this country without accidents/incidents apart from the odd game capture accident which normally happens due to bad piloting skills.
The question must be: Why all of a sudden all these accidents? The answer might not be clear to all, but I think we must seriously start looking at the quality of ab initio training in this country. I have seen some shocking examples of utmost bad training at some schools over the past few years. Instructors that send students solo without even teaching them an engine failure in the hover, engine failure in the climb/descent or how to handle a simple emergency like a governor failure, let alone the handling of a low Rrpm condition.
What can you expect? Accidents, accidents and more accidents!!!!!
