## Discrepancy

DURING PREFLIGHT, ENGINE RUNUP PILOT WAS UNABLE TO CYCLE PROP AND THEN NOTICED ZERO OIL PRESSURE ON THE OIL PRESSURE GAUGE, ENGINE SHUTDOWN.  INSPECTION REVEALED THE GEAR SHAFT ASSY IN THE OIL PUMP HOUSING WAS SHEARD.  MFG HAS ASKED US TO SEND THE ENGINE BACK TO THE FACTORY FOR EXAMINATION.  WE HAVE PHOTOS OF THE FAILED PART IF YOU TELL US HOW TO SEND THEM TO YOU.
