## Discrepancy

(CAN) THE PROP WAS INSTALLED ON THE RT SIDE OF ACFT.  WE RECEIVED NOTICE FROM MFG TECH SUPPORT THAT THIS PROP MAY HAVE A BLADE COLLAR INSTALLATION ISSUE.  UPON CLOSER INSPECTION, THE NR 1 BLADE COLLAR WAS MISSING.  WE SUSPECT IT FELL OFF DURING ENGINE OPERATION.  THE PROP WAS REMOVED AND SENT TO AN O/H FACILITY FOR CLOSER INSPECTION AND REPAIR OF THE REMAINING BLADE COLLARS.  AN INSPECTION WAS CARRIED OUT ON THE AFFECTED ENGINE.
