Tiedown hooks work to ground the ship, if you leave them installed. I do.
It occurred to me that the fuel truck will not be able to hook its ground wire to the exhaust pipe on my RV-14A (when it is finally finished). Where do they hook the ground wire on an RV?
It is not recommended to leave the tiedown rings installed.
Thanks for the responses. I guess I will plan on using the exhaust, installing the ground wire myself. I don't want to send a line guy under the plane. Of course, I will probably insist on fueling myself, too.
Good thing there are no line guys on this forum or smart enough to build
On an "{A" model it wouldn't be recommended to remove it.... it is the only thing preventing the rudder bottom from getting ground off in a less than ideal landing.
There are products that can be applied that will prevent a problem if concerned.
Years ago, in the interest of lighter weight, I ordered up a pair of solid Titanium rings from some Google search and made them fit. If I recall, I had to trim off the threaded end a bit and smooth the bottom of the ring where it touches paint. I now leave them on all the time, hook up the ground clip there and nothing has rotted off my airplane yet. Occasionally I remove them in search of more knots and see no sign of corrosion on the threads. Considering lightweight and performance goals, this purchase had poor return-on-investment.

Ok so let?s use our exhaust pipes to ground the aircraft. When the knuckle dragging lineman pulls the clamp down the stack and scores your stack, it is going to crack there.
Why don?t we use an airframe point to ground the plane? Add a bolt anywhere you want as the whole airframe is a common. You can add a grounding plug like the jets use or a simple bolt to clip the ground to if you refuse to tie your plane down.
The exhaust pipe is NOT designed to be a ground and a scratch on it is an invitation to a thermal crack. I use my tiedown rings but if you never tie down then add a jam nut to a bolt in the same hole and let your exhaust pipe live to do what it is designed for.
Dismount soap box...
