## Discrepancy

DURING FLIGHT, GREEN HYD SYSTEM QUANTITY DROPPED TO  THE RED DOT. FOLLOWED QRH. CRANKED THE GEAR.  STOPPED ON RWY.  APPEARS THE HYD LEAK IS COMING FROM THE BOTTOM  ELBOW OF LANDING GEAR SELECTOR 3GA. WE WILL REPACK  ELBOW WITH NEW BACK UP WASHER AND O-RING. WILL ALSO  ORDER 3GA VALVE FROM DFW JUST IN CASE ITS A CASE  LEAK.  FOUND ELBOW LEAKING. PACKING AND SEAL DAMAGED.  REMOVED AND REPLACED 3GA LANDING GEAR SELECTOR VALVE PACKING AND SEAL ON BOTTOM ELBOW REF. AMM 32-31-12-04. OPS CHECK GOOD. CYCLED LANDING GEAR 3 TIMES. NO LEAKS NOTED.
