Ron,

 

Randy is correct.

PS I stand back at each refueling after the line person attaches his ground to the nose gear or exhaust.  That takes care of grounding to the electrical system which is only connected to electrical things.  I worry more about the induced static indication from the AM radio playing in the hangar while I am waxing the fuel carrying wings.  Just don't brush your dog when the relative humidity is below 20% while sticking your free finger in the wing tank.

Ron, it is pointless to try and ground a fiberglass airplane. I would bet 99 percent of the non carbon lancairs are flying with no grounding. I have never heard of anyone having a problem..
Keep it light and leave it off..

Another couple of queries for those who have built the L320/360 aircraft.

 

1.       I notice that the instructions make no mention of earthing the fuel filler on the header tank. On my kit, which I purchased partly built with the wings completed, I notice that all the metal parts of the wing tanks are electrically bonded, including the fuel filler port inserts. However in the instructions for building the header tank, there is no mention of bonding the filler port. It would be quite simple to do with some copper bonding strap glassed into the inside of the forward deck, and passing through the flox bond where the tank is bonded to the forward deck. What has everyone else done?

2.       I am researching the firewall forward part of the manual, and notice they talk about using 2 layers of fibrefax behind the stainless steel fire shield which covers the firewall, all bonded into place with “ high temperature silicone”. As this section of my construction manual is dated 1994, I am wondering whether this is still the recommended process, or have fibrefax and high temperature silicone been superceded by something more up to date.

 

I appreciate any suggestions offered.
