## Discrepancy

WHILE PARKED ON THE RAMP, THE AIRPLANE WAS FOUND TO HAVE FUEL LEAKING FROM THE ACCESSORY CASE SEAL DRAIN LINE ON THE LT ENG.  THE ENG DRIVEN FUEL PUMP WAS FOUND TO HAVE A SHAFT SEAL LEAK THAT SEALED ITSELF WHEN PRESS WAS APPLIED WITH THE BOOST PUMP OR BY RUNNING THE ENG.  THE PUMP WAS REPLACED WITH SERVICEABLE. THIS IS THE 2ND INCIDENT OF IDENTICAL LEAKAGE THAT WE HAVE OBSERVED WITH THESE PUMPS.
