## Discrepancy

ON POST-FLIGHT INSPECTION, CREW NOTICED OIL LEAKING FROM LEFT PROPELLER.  MAINTENANCE DETERMINED SOURCE TO BE THE NR 1 PROP BLADE.  THE BLADE WAS REMOVED, AND THE BLADE SEAL COIL SPRING WAS FOUND TO BE BROKEN.  THE BLADE SEAL ASSEMBLY WAS REPLACED, THE BLADE REINSTALLED, AND THE PROPELLER RETURNED TO SERVICE.
