## Discrepancy

ACFT HAD PROP DE-ICE FAILURE LIGHT.  FLIGHT RETURNED TO MX BASE FOR REPAIRS.  TROUBLESHOOTING INDICATED DE-ICE TIMER FAILURE.  REPLACED AND GROUND RUN AND FUNCTION CHECKED CORRECT.  NEXT DAY LEFT ON FLIGHT AND WITHIN 20-30 MINUTES SAME FAILURE INDICATION.  DUE TO NO MX AT FWD LOCATION RETURN TO DEPARTURE BASE FOR REPAIR.  AFTER MUCH MORE INTENSE SCRUTINY FOUND DE-ICE BLADE LEADS BAD AND REPLACED ALL 4 ITEMS.  RUN/FUNCTION AND FLIGHT CHECKED GOOD.  NO FURTHER PROBLEMS.  SYS NOT MECHANIC FRIENDLY TO TROUBLESHOOTING.  LEADS ALMOST NEED TO BE REMOVED FROM BLADE TO THOROUGHLY OHM OUT AND FIND POTENTIAL PROBLEMS.
