## Discrepancy

DURING POST-FLIGHT CHECKS THE MAINTENANCE TECH DISCOVERED AN OIL LEAK FROM THE NO3 ENGINE. THE MAINTENANCE PROVIDER FOUND A LIP SEAL ON THE ACCESSORY GEARBOX FOR THE FUEL PUMP LEAKING. THE DEFECTIVE SEAL WAS REMOVED, AND A NEW CONDITION SEAL INSTALLED. LEAK CHECKS WERE SATISFACTORY, AND THE AIRCRAFT WAS RETURNED TO SERVICE.
