## Discrepancy

DURING TRANSIT CHECK WAS DETECTED AN HYDRAULIC LEAK ON RT MAIN LANDING GEAR WELL.  WELL WAS CLEANED AND SYSTEM WAS PRESSURIZED AND NO LEAK WAS DETECTED, HYDRAULIC SYSTEM WAS RECHARGED WITH 4 QUARTERS, ALL CORRECT. AT AGU, HYDRAULIC LEAK WAS DETECTED ON RIGHT SPOILER SELECTOR VALVE. SELECTOR VALVE LINES WERE TIGHTENED AND SYSTEM WAS CHECKED BY LEAKS IAW MM  29-10-26, ALL CORRECT. AT MEX VALVE WAS REPLACED AND TESTED IAW MM 29-10-06, HYDRAULIC SYSTEM WAS RECHARGED AT CORRECT LEVEL, ALL CORRECT.
