Narrative:
Receiving the B-727 the #3 and total fuel gauges were MEL'd. The crew decided to drain #3 tank and fill it to a known level, since we had minimum time to accomplish this, we were delayed. Just off IOE, and feeling rushed, I missed the xfeed position after the fuelers were finished. I had #1 and #3 xfeed open, and #2 closed. Not until descent did I notice this. As the flight continued the captain noticed the right wing getting heavy but since #3 and total fuel gauges inoperative it was not obvious what the problem was. I went back to see if we had a floating spoiler. When I returned I noticed the xfeeds were not in the standard position. The captain didn't want to chance feeding #3 engine from the #3 tank in case the fuel wasn't feeding so we elected to feed #3 engine from the #2 tank. We landed with approximately 5000 pounds out of balance. Contributing factors were feeling rushed, #3 tank and total fuel gauges inoperative and #1 boost pump a little stronger than #3 pumps. Callback conversation with reporter revealed the following: aircraft is a B-727. Reporter states #3 fuel gauge, only, inoperative. Inoperative total is not a MEL item. Normal operation is with #1 and #3 xfeeds closed for tank to engine flow. Xfeeds were left open as a result of so's distraction in abnormal situation, and associated schedule pressure. Now, so states that these position would stand out like bull's eyes. #1 boost pump stronger than #3, and once error was committed, inoperative gauge made accurate determination of fuel situation, impossible. Flight crew noticed wing heavy condition during descent. Captain's heavy workload led to trouble-shooting without so's input. Captain's solution did not alleviate problem since solution was to feed #3 engine from the #2 tank. So states that she failed to convey what she felt she had done wrong. Flight crew counseled by company. Fuel imbalance limitation is 1000 pounds.

Title: B-727 EXCEEDED FUEL IMBALANCE LIMITATIONS DURING LNDG.
Narrative: RECEIVING THE B-727 THE #3 AND TOTAL FUEL GAUGES WERE MEL'D. THE CREW DECIDED TO DRAIN #3 TANK AND FILL IT TO A KNOWN LEVEL, SINCE WE HAD MINIMUM TIME TO ACCOMPLISH THIS, WE WERE DELAYED. JUST OFF IOE, AND FEELING RUSHED, I MISSED THE XFEED POS AFTER THE FUELERS WERE FINISHED. I HAD #1 AND #3 XFEED OPEN, AND #2 CLOSED. NOT UNTIL DSCNT DID I NOTICE THIS. AS THE FLT CONTINUED THE CAPT NOTICED THE R WING GETTING HVY BUT SINCE #3 AND TOTAL FUEL GAUGES INOP IT WAS NOT OBVIOUS WHAT THE PROB WAS. I WENT BACK TO SEE IF WE HAD A FLOATING SPOILER. WHEN I RETURNED I NOTICED THE XFEEDS WERE NOT IN THE STANDARD POS. THE CAPT DIDN'T WANT TO CHANCE FEEDING #3 ENG FROM THE #3 TANK IN CASE THE FUEL WASN'T FEEDING SO WE ELECTED TO FEED #3 ENG FROM THE #2 TANK. WE LANDED WITH APPROX 5000 LBS OUT OF BAL. CONTRIBUTING FACTORS WERE FEELING RUSHED, #3 TANK AND TOTAL FUEL GAUGES INOP AND #1 BOOST PUMP A LITTLE STRONGER THAN #3 PUMPS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: ACFT IS A B-727. RPTR STATES #3 FUEL GAUGE, ONLY, INOP. INOP TOTAL IS NOT A MEL ITEM. NORMAL OP IS WITH #1 AND #3 XFEEDS CLOSED FOR TANK TO ENG FLOW. XFEEDS WERE LEFT OPEN AS A RESULT OF SO'S DISTR IN ABNORMAL SIT, AND ASSOCIATED SCHEDULE PRESSURE. NOW, SO STATES THAT THESE POS WOULD STAND OUT LIKE BULL'S EYES. #1 BOOST PUMP STRONGER THAN #3, AND ONCE ERROR WAS COMMITTED, INOP GAUGE MADE ACCURATE DETERMINATION OF FUEL SIT, IMPOSSIBLE. FLC NOTICED WING HVY CONDITION DURING DSCNT. CAPT'S HVY WORKLOAD LED TO TROUBLE-SHOOTING WITHOUT SO'S INPUT. CAPT'S SOLUTION DID NOT ALLEVIATE PROB SINCE SOLUTION WAS TO FEED #3 ENG FROM THE #2 TANK. SO STATES THAT SHE FAILED TO CONVEY WHAT SHE FELT SHE HAD DONE WRONG. FLC COUNSELED BY COMPANY. FUEL IMBALANCE LIMITATION IS 1000 LBS.
