## Discrepancy

BLADE CUFF MISSING FROM BLADE ON NR 1 PROP.  ACFT PARTS WERE FOUND ON RUNWAY.   IT WAS DETERMINED THE PART SEPARATED DURING THE TAKEOFF ON FLT-8562.   THE ACFT WAS TAKEN OUT OF SERVICE FOR REPAIR.  INVESTIGATION REVEALED THE PART MAY HAVE BEEN DAMAGED FROM TOOL USED TO REMOVE THE SPINNER DURING A PROP BALANCE SESSION UNDER WO-273210. THE TOOL WAS LOCATED  AND A TEST CONDUCTED TO DETERMINE IF THE TOOL (HOMEMADE) COULD HAVE CAUSED THE DAMAGE. THIS WAS CONFIRMED AND THE TOOL WAS REMOVED FROM SERVICE.   A NEW BLADE CUFF WAS REINSTALLED. ACFT RETURNED TO SERVICE.
