## Discrepancy

WHILE UN-COWLING, RT ENGINE MAINTEANCE FOUND A PIECE OF STAINLESS STEEL IN THE LOWER SECTION OF COWL.  INVESTIGATION REVEALED A HOLE IN THE LT SIDE OF ASPIRATOR ASSEMBLY ABOVE THE OIL COOLER.  THE ASPIRATOR WAS REPLACED AND AIRCRAFT SINCE RETURNED TO SERVICE.  THE MOST PROBABLE CAUSE WOULD BE FATIGUE CRACKING LEADING TO THE PIECE FALLING INTO THE LOWER COWLING.
