This AD was prompted by a report indicating that burnt wiring was discovered in the wire bundle at station 160.000 in the electrical/electronics (E/E) compartment. We are issuing this AD to detect and correct chafing of the wire bundle at station 160.000 against the support bracket located on the aft right radio rack, which could lead to shorted or burnt wires and consequent smoke and fire in the E/E compartment.
