## Discrepancy

(CAN) THE C3411-2 BEARING RACE WAS INSTALLED DURING THE ASSEMBLY STAGE OF THE OVERHAUL AND DURING THE BEARING SEATING INSPECTION IT WAS FOUND THAT THE BEARING SEATING AREA WAS NOT CONTACTING THE PROPELLER HUB. THE BEARING WAS REMOVED AND CHECKED FOR FLATNESS ON A PRECISION GRANITE STONE AND AN AREA 2" LONG DID NOT CONTACT THE STONE. THE BEARING WAS REMOVED FROM SERVICE.
