## Discrepancy

RUNNING HYDRAULIC LEAKAGE AT CTR SYS WING FLIGHT CONTROL SHUTOFF VALVE AT LT MAIN LANDING GEAR WHEEL WELL.  FOUND INLET VALVE (LOWER) TUBING LEAKING.  AFTER TIGHTENING GOT LEAKAGE TO 1 DROP PER MINUTE.  NOW ITS WITHIN DISPATCH LIMITS AS PER AMM.  SUGGEST TUBE & UNION REPLACEMENT.  REPLACED CENTER SYSTEM WING FLIGHT SHUTOFF VALVE. OPERATION CHECKS OKAY. NO LEAKS NOTED.
