## Discrepancy

DURING A 50 HOUR INSPECTION THE SPINNER ASSEMBLY WAS DETECTED TO BE VERY LOOSE ON THE PROP.  UPON FURTHER EXAMINATION BOTH SPINNER ATTACH PLATES WERE FOUND CRACKED ALL THE WAY AROUND FOUR OF SIX PROP ATTACH BOLT HOLES.  CRACKS EMANATED FROM THE CORNER OF EACH BOLT HEAD AND WENT IN EACH DIRECTION ALL THE WAY TO THE EDGE OF THE ATTACH PLATES (3 CRACKS ON ONE PLATE AND ONE ON THE OTHER).  AFTER CHECKING THE PARTS CATALOG IT WAS DETERMINED THAT THE SIX WASHERS REQUIRED FOR THE ATTACH BOLTS HAD BEEN OMITTED DURING THE PROPELLER ASSEMBLY.  DURING REPAIR OF AC, INSTALLED THE SIX WASHERS REQUIRED BY THE MFG CATALOG.  BELIEVE IT WILL PREVENT FUTURE REOCCURRENCE.
