Any stats on the number of occurrences, without wire strike kit of where the wire bites, is it mast or skids?
Two instances spring to mind that affected me quite closely - in your line of business too....
An Alouette II, wire strike - three wires. One around the mast and rotating controls, the second through the cabin - you can guess the outcome and the third hit the skid posts.
A 350 with a side mount, hit a single wire with the forward crosstube - went under the camera operator's feet by inches - would have taken his legs off if they had been flying a foot lower.
It's quite arbitrary which part of the helicopter is hit by the wires.
The answer is a good recce before you fly the shot.
