## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED AND THE AIRCRAFT DIVERTED TO COS DUE TO A YELLOW HYDRAULIC SYSTEM RESERVOIR LOW LEVEL MESSAGE AFTER TAKEOFF. THE AIRCRAFT LANDED SAFELY AT COS WITHOUT FURTHER INCIDENT. MAINTENANCE REPLACED THE YELLOW HYDRAULIC SYSTEM RESERVOIR LOW LEVEL SWITCH PER AMM 29-13-41 AND ACCOMPLISHED A SATISFACTORY OPERATIONAL CHECK.
