## Discrepancy

AIRCRAFT EXPERIENCED A TOTAL LOSS OF HYDRAULIC FLUID FROM THE LT SYSTEM AFTER RETRACTION OF LANDING GEAR DURING CLIMBOUT. COMPLIED WITH COM PROCEDURES AND THE FLIGHT RETURNED FOR AN UNEVENTFUL LANDING BACK AT MSP. IT WAS NOTED THAT THE RT HYDRAULIC SYSTEM MAINTAINED GOOD PRESSURE AND QUANTITY. MAINTENANCE FOUND THE LT HYDRAULIC SYSTEM FLUID QUANTITY LIMITER BROKEN AT THE INPUT PORT AND REPLACED IT. SYSTEM WAS RESERVICED, BLED, AND LEAK CHECKED AND ALL SYSTEM COMPONENTS OPERATED NORMALLY. AIRCRAFT RETURNED TO SERVICE.
