## Discrepancy

(CAN) CREW REPORTED PROP DEICE CAUTION ON A FEW MINUTES AFTER SELECTED. SWITCH RECYCLED A FEW TIMES, CAUTION EVENTUALLY WENT AWAY, NO OTHER CAUTIONS NOTED.  PROBLEM COULD NOT BE DUPLICATED AT MAINTENANCE BASE.  TESTING OF COMPONENTS DID NOT REVEAL ANY FAULTS.  A DIRTY SLIP RING MAY HAVE BEEN THE CAUSE.  (TC NR 20091130004)
