## Discrepancy

AIRCRAFT DIVERTED DUE TO THE NR 1 HYDRAULIC SYSTEM FLUID DEPLETING IN FLIGHT. FOUND THAT THE NOSE GEAR UP LOCK ASSEMBLY WAS LEAKING FLUID, AND A HYDRAULIC LINE IN THE AFT MAINTENANCE COMPARTMENT HAD A CRACK. MAINTENANCE INSTALLED A REPAIRED UP LOCK ASSEMBLY AND A NEW TUBE ASSEMBLY TO RETURN THE AIRCRAFT BACK TO SERVICE. THE AIRCRAFT WAS ON A PART 91 FLIGHT AT THE TIME.
