## Discrepancy

DURING ROUTINE INSPECTION OF THE DRIVE FLANGE A CAST PLASTIC SUPPORT BUTRESS WAS FOUND CRACKED.  A NEW DRIVE FLANGE WAS INSTALLED.  SUGGEST THAT THE ALTERNATE METAL DRIVE FLANGE BE USED INSTEAD OF THE PLASTIC DESIGN AS ONLY THE PLASTIC DRIVES FAIL.  THE WEIGHT OF THE PART SEEMS TO BE THE MFG PRIMARY CONSIDERATION IN THE SELECTION FOR THIS PARTS MATERIAL.  (K)
