How does one insure a good bond between the engine mount and the airframe??
I was installing a freshly painted engine mount to the airplane and in the back of my head I was figuring on the bonding strap between the engine and mount would take care of any grounding issues. Then it dawned on me that a good bond between the engine and mount doesn't necessarily mean the mount is bonded to the airframe...
I painted up the lugs that attach to the firewall and also the mount itself and used new hardware throughout. I guess its possible there is some bare metal contact somewhere in the four attach points that would suffice for a good bond. I'd rather not scrape to bare metal unnecessarily so I ask you guys, what do you do??
Thanks
