wicks in Sedona and have not noticed any additional pitting since
installing them.
My question to the listers:
1) Have any of you
experienced similar pitting problems?
2) Is the 4-5 foot
grounding strap too long?
3) Should the bottom
skin be grounded as well?
4) Have I adequately
dealt with this issue by installing the wicks?
I am heading back to the paint shop on Friday and
want to make sure I have resolved this issue. Any comments are greatly
appreciated!
Craig, I have found
carbon is very conductive but you have to sand down to carbon fibers. I
would check the conductivity of every skin back to a common point. That is
the wing top skin and the wing bottom skin, the horizontal top and the
horizontal bottom, the fuselage top and bottom....you get the picture. I
have been told a max of 10 ohms is acceptable. I would think if each skin
is well bonded to all others, 10 ohms would be pretty easy to achieve. I
have seen .03 ohm in a distance of 5 feet.
