## Discrepancy

WHILE ACFT WAS PARKED IN HANGAR, THE ACFT WAS OBSERVED TO HAVE FUEL DRIPPING FROM THE ENG ACCESSORY DRIVE DRAIN LINE.  THE ENG DRIVEN FUEL PUMP WAS FOUND TO HAVE A SLOW LEAK FROM THE DRIVE SHAFT SEAL WHILE DEPRESSURIZED, WHICH CEASED WHEN PRESS WAS APPLIED TO THE FUEL SYS WITH THE BOOST PUMP OR BY RUNNING THE ENG.  THE PUMP WAS REPLACED WITH SERVICEABLE.
