## Discrepancy

FOUND LEFT AILERON SHUTOFF SWITCH HARNESS TO BE FRAYED AND SHORTING TO GROUND NEAR SHUTOFF SWITCH.  VERIFIED THE BLUE WIRE 1D2-22, IN WIRE HARNESS 1D1ZB22 (WHT) TO BE COMPLETELY CUT OFF.  THIS CONDITION CAUSES THE LEFT AILERON HARD OVER PROTECTION TO BE INOPERATIVE AND UNDETECTED.  THERE IS NO COCKPIT INDICATION OF THIS CONDITION.
