Why not run individual ground wires AND also make short ground wire connections to the airframe. Then if an individual wire should develop a problem, there still is a path to a ground.My airplane is primarily rivited aluminum construction. It is my understanding that the metal airframe can be used as the return leg of DC electrical circuits. My question is, is it worth is to use the airframe instead of dedicated return wires, given all the bonding consideratons of an electrified airframe?
