What was found
THE LOW POWER GEAR UP WARNING SWITCH ON THE THROTTLE QUADRANT WAS FOUND BROKEN INTERNALLY. WHEN THE THROTTLES WERE ADVANCED THE SWITCH WOULD OPEN AND SHORT TO GROUND CAUSING THE LANDING GEAR CONTROL CIRCUIT BREAKER TO OPEN. WHEN THE THROTTLES WERE PULLED BACK TO THE STOP, THE SWITCH WOULD CLOSE AND THE LANDING GEAR SYSTEM WOULD FUNCTION NORMALLY. SUBMITTER STATED THE AGE OF THE SWITCH, NUMBER OF CYCLES, IS POSSIBLY THE CAUSE OF FAILURE. (X)
