## Discrepancy

PROPELLER ASSEMBLY REMOVED FROM AIRCRAFT FOR HUB MAJOR INSPECTION.  UPON INITIAL RECEIVING INSPECTION THE BLADE PIN BEARING INSERT WAS FOUND TO BE IN AN OVAL FASHION.  FURTHER INSPECTION SHOWED THAT THE INSERT HAD WORN TO .082 AT THE THINNEST POINT AND .099 AT THE THICKEST POINT.  INSERT WAS REMOVED AND SENT TO MANUFACTURER FOR FURTHER EVALUATION.
