## Discrepancy

CREW STATED THAT WHILE ON FINAL FOR RUNWAY 19L, THE GEAR DID NOT COME DOWN. THEY REQUESTED DELAY VECTORS TO RUN PROCEDURE. THEY PERFORMED PROCEDURE A SUCCESSFULLY, GEAR EXTENDED. THEY DECLARED AN EMERGENCY AND LANDED WITHOUT FURTHER INCIDENT.  FOUND THE RH MAIN LANDING GEAR BRACING CYLINDER LEAKING. THEY REMOVED AND REPLACED THE RH MLG BRACING CYLINDER WITH A SERVICEABLE UNIT IAW MM32-30-11. LEAK CHECK WAS NORMAL, HOWEVER THEY WERE UNABLE TO PERFORM THE REQUIRED OPERATIONAL CHECK. LANDING GEAR LOCKS WERE INSTALLED AND THE AIRCRAFT WAS INSPECTED AND FERRIED TO KYIP IN ORDER TO PERFORM THE OPS CHECK. UPON ARRIVAL IN KYIP THE LANDING GEAR LOCKS WERE REMOVED AND SEVERAL LANDING GEAR EXTENSION AND RETRACTION TESTS WERE PERFORMED IAW MM 32-30-00. OPS AND LEAK CHECKS WERE BOTH NORMAL AT THIS TIME
