What was found
OPERATIONAL CHECKS AT INSPECTION INTERVALS TYPICALLY FIND THE VENT HEATS INOPERATIVE DUE TO THE ELECTRICAL CONNECTION ON THE TUBE ITSELF. USING A PROBE AND INSERTING IN THE HOLE WHERE THE HEATING COIL TERMINATES PRODUCES A SPARK AND THEN THE COIL WILL HEAT PROPERLY AFTER THE CONNECTION IS MADE. THIS DEFECT IS FOUND NEARLY EVERY INSPECTION ON TWO KING AIRS. SUBMITTER STATED A REDESIGN OF THE TERMINATION WOULD MOST LIKELY CURE THE EXISTING POOR CONNECTION. (X)
