## Discrepancy

AIRCRAFT OPERATOR REPORTED A TOTAL LOSS OF OIL PRESSURE AND QUANTITY 20 MINUTES AFTER TAKE OFF FROM LAX.  THIS RESULTED IN A IFSD AND AN ATB.  INVESTIGATION AT THE ENGINE REPAIR STATION REVEALED THAT ONE OF THE TWELVE RETAINING BOLTS FOR THE NR 7 BEARING WAS MISSING.  THE BOLT WAS FOUND IN THE BEARING SCAVENGE LINE.  THE BOLT HAD BLOCKED THE PIPE AND CAUSED THE ENGINE TO PUMP ALL OF THE OIL OVERBOARD.
