## Discrepancy

CRACK IN PROPELLER HUB WAS FOUND DURING AN INSPECTION TO FIND A REASON FOR A GREASE LEAK COMING OUT OF THE PROP SPINNER.  THE REAR HUB HALF WAS FOUND TO BE BROKEN IN TWO AROUND ONE BLADE SOCKET.  ANY FURTHER OPERATION WOULD HAVE CAUSED A COMPLETE BLADE SEPARATION.  HUB WAS SENT TO MFG. FOR FURTHER EVALUATION.
