## Discrepancy

FUEL LEAK OBSERVED UNDER #2 ENGINE. GROUNDED - YES. CHECKED AND FOUND LEAK AT #2 ENG HPTACC DRAIN. LEAK IS 13 DPM WITHIN LIMITS PER B737-800 AMM 71-71-00 FIG 605. RELEASED PER PLT FOR REPAIR WITHIN 25 FC. REMOVED AND REPLACED #2 ENGINE HPTACC VALVE REF AMM 75-21-01-000-801-F00 AND AMM 75-21-01-400-801-F00. OPS AND LEAK CHECK GOOD. THIS CLEARS PLT DEFERRAL.
