IT WAS ALSO NOTED THAT THE INTERIOR SEEMED TO HAVE A OILY RESIDUE LIKELY FROM THE MISTING OIL.   UPON OPENING THE RADOME IT WAS COMPLETELY COVERED IN HYDRAULIC FLUID.  THE MAIN SYSTEM HYDRAULIC PRESSURE STAINLESS BRAIDED FLEX LINE LINE TO THE MAIN SYSTEM GAUGE LOOKED LIKE RUBBER WAS PUSHING THOUGH THE BRAIDING.  A SMALL PILE OF RUBBER PARTIALS WERE BELOW THE HOSE.  THEN TURNING  ON THE HYDRAULIC PUMP AND THE HYD. LINE INSTANTLY PRODUCE A FINE MIST OF HYDRAULIC FLUID THAT FILLED THE NOSE QUICKLY.
