## Discrepancy

RED DYE LEAKAGE FROM THE PROP CYLINDER 'DOME' GASKETS.  SPECIFICALLY WHERE THE DOWL PINS ARE.  HAS BEEN A RECURRING PROBLEM JUST AFTER OVERHAUL.  SUBMITTER STATES THIS SHOP HAS SEEN 7 PROPS LEAK AFTER THE OIL-FILL MOD.  THESE OVERHAULS WERE PERFORMED BY 4 DIFFERENT PROPELLER REPAIR STATIONS.  AFTER RESEAL, 2 OF THE 7 HAVE SHOWN SUBSEQUENT LEAKAGE AND NEED FOR RESEAL.  SUGGEST MCCAULEY HAVE AN O-RING INCORPORATED WITH OIL-FILL MOD.
