## Discrepancy

(CAN) DURING A REGULARLY SCHEDULED INSPECTION, THE RIGHT HAND IGNITION LEAD WAS FOUND TO BE BROKEN AT THE IGNITER ATTACHMENT END. THE LEAD HAD A TSN OF 833.9 HOURS.  THIS OPERATOR HAS HAD NUMEROUS PROBLEMS WITH IGNITION LEADS FAILING. IT SEEMS TO BE MOSTLY THE IGNITER END WEARING OUT EXTREMELY QUICKLY, EITHER BURNING THE PIN IN THE IGNITER OR ARCHING THROUGH THE WHITE INSULATOR TIP OF THE LEAD.
