What was found
DURING FLIGHT AFTER SHORTY AFTER LEVEL OFF, THE FLIGHT CREW EXPERIENCE A LOW HYDRAULIC PRESSURE MALFUNCTION AND AIR RETURNED BACK TO BASE. THE EMERGENCY LANDING GEAR HANDLE WAS MANUALLY ACTUATED DUE TO THE FAILURE AND THE AIRCRAFT LANDED WITHOUT FURTHER INCIDENT. MAINTENANCE INSPECTED THE HYDRAULIC SYSTEM AND FOUND THAT A HYDRAULIC LINE CHAFFED AGAINST A FRAME PIECE CAUSING A SMALL LEAK IN THE SYSTEM. THE LINE WAS REPLACED, THE SYSTEM WAS SERVICED, AND THE LANDING GEAR WAS CYCLED ON AIRCRAFT JACKS TO VERIFY PROPER OPERATION POST REPAIR. ALL SYSTEM FUNCTIONS WERE NORMAL, AND THE AIRCRAFT HAS BEEN RETURNED TO SERVICE.
