## Discrepancy

(CAN) DURING CRUISE AT FL110, THE CREW OBSERVED THE RT ENGINE CHIP DETECTOR LIGHT ILLUMINATED.  APPROX 3 MIN LATER, THE OIL PRESSURE DROPPED TO ZERO. THE ENGINE WAS SECURED AND THE FLIGHT DIVERTED, WHERE SINGLE ENGINE LANDING WAS PERFORMED WITHOUT INCIDENT.  ENGINE INVESTIGATION FOUND FRACTURED TEETH ON A FAA/PMA RGB SUN GEAR INSTALLED 515 HRS PRIOR.
