## Discrepancy

ON INSPECTION OF THE OIL SCREEN IT WAS NOTICED THAT THERE WAS FOREIGN MATERIAL IN THE OIL SCREEN.  THIS MATERIAL WAS TAKEN TO AN O/H SHOP FOR ANALYSIS.  WE WERE INSTRUCTED TO PULL 1 CYLINDER AND LOOK AT THE THE MAIN BEARING AND NOTICED THAT A PIECE OF IT WAS MISSING. THE ENGINE WAS PULLED AND REPLACED.
