## Discrepancy

(CAN) PROPELLER WAS FOUND TO BE CRACKED BETWEEN LAMINATIONS, INSIDE THE INTERNAL HUB. MANUFACTURER INDICATES THIS MAY HAVE BEEN CAUSED BY MOISTURE CONTENT FLUCTUATIONS, WHICH WOULD CAUSE INCONSISTANT PROP TORQUE SETTINGS.THERE WAS NO EVIDENCE OF A LOOSE PROP.  PROP WAS ALSO QUITE OLD.  REPLACED WITH NEW.
