Summary:
The tail rotor contacted a small bush during training involving landings on sloping ground. Examination of the tail rotor revealed minor damage and the tail rotor was replaced. The instructor stated that, although he was aware of the bush, he incorrectly assessed its position and distance from the tail rotor. The bush has been trimmed.

And who says they have no sense of humour!!!?

I know of one like that involving a tree

Bush trimming
 

There's nothing wrong with trimming the odd bush or two!
