## Discrepancy

AIRCRAFT WAS GROUNDED: LAST 10 MIN OF FLIGHT SIGNIFICANT ODOR / FUME EVENT. MAINTENANCE FOUND A LARGE QUANTITY OF RESIDUAL HYDRAULIC FLUID IN CENTER KEEL BEAM OF MAIN LANDING GEAR WHEEL WELL AND DETERMINED THAT THE APU HAD INGESTED THIS FLUID CAUSING IN THE ODOR EVENT. MAINTENANCE CLEANED THE RESIDUAL FLUID UP AND ACCOMPLISHED A LEAK CHECK OF THE HYDRAULIC SYSTEM WITH NO LEAKS BEING IDENTIFIED. ALSO ACCOMPLISHED A SATISFACTORY OPERATIONAL CHECK OF THE APU AND ENGINES WITH NO ODORS BEING NOTED.
