## Discrepancy

DURING INSPECTION, FOUND TKS ANTI-ICE FLUID LEAKING FROM RIGHT SIDE OF NOSE WHEELWELL.  TRACED LEAK TO AFT SIDE OF FORWARD PRESSURE BULKHEAD.  FOUND O-RINGS ON FORWARD PRESSURE BULKHEAD FITTINGS DEFECTIVE AND PUDDLE OF TKS FLUID IN FLOOR BOARDS.  REPLACED O-RINGS.  SUBMITTER STATED TKS FORWARD O-RINGS DO NOT HOLD UP WELL AND FITTINGS LOCATION IS RARELY LOOKED AT.  BETTER O-RINGS NEEDED AND TKS FITTINGS NEED TO BE LOOKED AT CLOSELY.
