## Discrepancy

(CAN) ENGINE OIL COOLER/BLOWER ASSY DISASSEMBLED AT CUSTOMER'S REQUEST.  IMPELLER WAS FOUND CRACKED (1/2) DURING FPI INSPECTION.  MANUAL SPECIFIES THAT FPI IS CARRIED OUT EVERY 300 HOURS, HOWEVER, THIS CRACK WAS FOUND IN AN AREA NOT SPECIFIED IN THE BELL MANUAL, AS REMOVAL OF THE OIL COOLER/BLOWER IS NOT CALLED FOR.
