## Discrepancy

HYDRAULIC PUMP CIRCUIT BREAKER POPPED IN FLIGHT AND MAIN SYSTEM WOULD NOT HOLD PRESSURE. CREW DECLARED AN EMERGENCY AND SAFELY LANDED AT KHYI. MAINTENANCE FOUND HYDRAULIC MANIFOLD CAP TOO BE LOOSE AS WELL AS A LEAK ON INLET, ON FILTER HOUSING AND SUBSEQUENTLY SECURED THE MANIFOLD CAP AS WELL AS REPLACING THE PACKINGS, O-RINGS, AND FILTER. LEAK/OP CHECK WAS PERFORMED AND FOUND SATISFACTORY.
