## Discrepancy

CUSTOMER WAS INVESTIGATING AN ABNORMAL GREASE LEAK ON THE RIGHT HAND PROPELLER.  REMOVED THE SPINNER, DISCOVERED THAT THE ENGINE-SIDE HUB HALF WAS VISIBLY CRACKED.  CRACKS ARE LOCATED ON THE PROPELLER MOUNTING FLANGE HUB HALF, LEAD EDGE SIDE OF BLADE SOCKETS NUMBER 1 AND 2.  CRACKS RUN FROM HUB PARTING SURFACE TO MOUNTING FLANGE.
