Unsafe Condition
The ADG power feeder harness wire (aromatic polyimide type) has chafed on the backshell of its own connector (P1XC), resulting in a short circuit, wire damage, and disconnection from the ADG. This could lead to the loss of emergency power to critical systems, affecting aircraft controllability.
