## Discrepancy

AIRCRAFT WAS GROUNDED: PILOT REPORTS DIRTY SOCK ODOR FROM COCKPIT TO AFT CABIN STARTED AFTER T.O. AND FOR 40 MIN INTO FLIGHT. MAINTENANCE FOUND THE OIL COOLER LEAKING AND DETERMINED THAT WAS THE CAUSE OF THIS EVENT. REMOVED AND REPLACED THE APU OIL COOLER IAW CARD 26L000049004. OPS AND LEAK CHECK GOOD.
