Whatever the reason it shows that blades can fail when least expected. (Murphy’s law).
That may be true Lu, and several manufacturers can testify to that.
But the situation (at least in Oz at the moment) is that if the blade life of an R22 is exceeded, you can
expect it to break. It seems to be a trend and is not a random act of suprises.
....having said that:
1. Can anyone confirm/deny that this blade cracking has occurred in blades that are within their lfe limit?
2. Does lowering the mandatory life of a blade, stop people from exceeding it?
