## Discrepancy

PILOT REPORTED OIL LEAKING OUT OF RIGHT ENGINE.  MAINTENANCE DISCOVER #2 ENGINE OIL SCAVENGE PUMP HAVING A PINHOLE LEAK AND THE HOUSING WAS REPLACED.  INSPECTION DETERMINED THAT CAVITATION EROSION OF THE PUMP BODY IN A CORNER OF THE CAVITY HAD CREATED A HOLE.  THIS IS FREQUENT ON THESE PUMP HOUSINGS.  POST REPLACEMENT OF PUMP HOUSING LEAK CHECK WAS GOOD.
