## Discrepancy

OIL WAS FOUND SEEPING FROM THE TURBO SCAVENGE DRIVE ASSEMBLY.  IF THE OIL WAS WIPED FROM THE PUMP IT WOULD RETURN AFTER JUST ONE SHORT FLIGHT.  THE OIL WAS SEEPING FROM THE SEAM WHERE BOTH HALVES OF THE DRIVE ASSEMBLY MEET.  THIS PUMP WAS REPLACED 22.1 HOURS PRIOR TO THIS INCIDENT FOR THE SAME REASONS.  THE DRIVE ASSEMBLY WAS REMOVED AND REPLACED WITH A NEW DRIVE ASSEMBLY OF THE SAME PART NUMBER.(K)
