## Discrepancy

DETAILS EXTRACTED FROM MAJOR DEFECT REPORT: DAMAGE IN THE FORM OF SLASH TYPE CUTS TO THE DE-ICE BOOT WAS FOUND ON THE RIGHT PROPELLER, NR 3 BLADE, WHICH AS A RESULT REQUIRED THE PROPELLER BLADE TO BE REPLACED.  DURING REPLACEMENT OF THE NR 3 BLADE SERIAL NUMBER 851372 ENGINEERS DISCOVERED THAT THE BLADE COLLARS WERE MISSING FROM THE NR 4 BLADE ASSY.  SEPARATION OF THE BLADE COLLARS IS CURRENTLY UNDER INVESTIGATION BY THE TSB DUE TO A PREVIOUS COLLAR SEPARATION AND IMPACT DAMAGE ON ANOTHER AIRCRAFT.
