Part: VALVE — STUCK (RT WING) · airframe 3,478 hrs · 1,675 cycles

DURING CLIMB OUT, ON FERRY FLT, A FUEL IMBALANCE WAS OBSERVED ON FUEL GUAGES. ON FURTHER INSP FROM CABIN, FUEL WAS STREAMING OUT OF RT WING IN AREA OF PLENUM. IT WAS DECIDED BY CREW TO RETURN TO DEPARTURE. FUEL DOES NOT LEAK WHILE ACFT IS ON GROUND. AFT VENT FLOAT NON RETURNING VALVE (VENT DUCT) WAS STUCK IN OPEN POSITION CAUSING LEAK INTO PLENUM AND INTO THE VENT. REMOVED AFT FLOAT VENT VALVE PN 16F123 NSN AND INSTALLED NEW VENT VALVE PN 16F123 NSN. PERFORMED LEAK AND OPS CHECK WITH NO DEFECTS AT THIS TIME. WORK DONE REF AMM 28-15-01.

INFLIGHT - A THICK TRAIL OF FUEL LEAKING FROM THE RT WING WAS BROUGHT TO OUR ATTENTION BY THE FA. AN APPROX 350 LBS FUEL IMBALANCE CONFIRMED THE RT FUEL LEVEL WAS LOWER. THE TRAIL STOPPED MOMENTARILY BUT RETURNED. WERE ABLE TO MAINTAIN FUEL BALANCE THRU THE CROSSFLOW VALVE FOR OUR RETURN LANDING TO DEPARTURE. AFTER LANDING, A QUICK INSP CONFIRMED FUEL HAD BEEN LEAKING FROM THE NACA VENT AREA. AFT TANK FLOAT (VENT DUCT) WAS STUCK IN OPEN POSITION. REMOVED AFT FLOW VENT VALVE AND INSTALLED NEW VALVE. PERFORMED LEAK AND OPS CHECK WITH NO DEFECTS NOTED AT THIS TIME. WORK DONE REF AMM 25-15-01
