## Discrepancy

THE FLIGHT CREW REPORTED THAT THEY EXPERIENCED A LOSS OF HYDRAULIC PRESSURE IN FLIGHT AND THAT AN EMERGENCY LANDING GEAR EXTENSION WAS PERFORMED. THE AIRCRAFT LANDED WITHOUT FURTHER INCIDENT. BUR MAINTENANCE FOUND THE HYDRAULIC LINE TO THE #1 FLAP FAILED AND THE LINE WAS REPLACED. ALL PRESSURE, LEAK, AND OPERATIONAL CHECKS WERE NORMAL AND THE AIRCRAFT WAS RETURNED TO SERVICE. NO FURTHER LOSS OF HYDRAULIC PRESSURE HAS BEEN NOTED TO DATE.
