## Discrepancy

THE PART THAT IS DEFECTIVE INSIDE OF THE PROPELLER IS CALLED THE MUSHROOM, PN A856.  WHILE DISASSEMBLING THE FEATHER SPRING KIT DURING IRAN (INSPECT, REPAIR AS NECESSARY) INSPECTION, THE MUSHROOM WAS FOUND BROKEN.  WHILE PERFORMING A DYE-PENETRANT INSPECTION ON THE SAME PART OF THE OTHER PROPELLER, FOUND IT, TOO, WAS CRACKED.
