## Discrepancy

PILOT REPORTED GEAR WOULD NOT CYCLE DOWN.  GEAR WAS PUMPED DOWN MANUALLY.  FLUID WAS OBSERVED LEAKING FROM LEFT HYDRAULIC FILTER HOUSING.  HOUSING WAS REMOVED AND IT WAS DISCOVERED THAT THE LAST FEW THREADS ON THE HOUSING SIDE HAD CRACKED THROUGH.  HOUSING AND O-RING WERE REPLACED AND SYSTEM SERVICED AND FUNCTIONALLY TESTED.  (X)
