I'm an airplane mechanic and while that is not a bad job, it's not great either. You want to wire it where if either tries to rotate CCW, it tightens the other. The wire should not be over the end of the oil filter like that. The oil drain plug is wired straight up to the filter. so if the filter tries to unscrew the drain plug won't do any assisting at all. It'll be pulling right on the safety wire.Not bad, but that would never pass inspection for a Cessna.You also ALWAYS tuck in that end of the safety wire. Bend it against the screw. You never leave it sticking out like that. You stick your hand in there to work and you'll jab the **** out of yourself. Notice in the diagram the end is tucked away.This is the approved method.
