Narrative:
Arrived at aircraft with 57400 pounds of fuel on board. Mechanic was xferring fuel to center tank to comply with current directives regarding center tank fuel requirements. 1100 pounds of fuel was xferred to the center tank. As is the case with less than full main tanks, 1 main is overfilled and then xferred to the center tank. It appears that the fuel was xferred from the light tank to the center tank resulting in an approximately 2600-2800 pound imbal. This was discovered after engine start and required a delay of 12 mins at 2200 pounds per hour ff to bring aircraft into limits. Lessons learned are that flight in older B767-200's will be accompanied by a continuous fuel confign light due to fluctuating fuel gauges going over 1200 pounds. This might prevent the pilot from seeing another problem associated with the fuel confign light.
Original NASA ASRS Text
Title: A B767-200 INCURRED A FUEL IMBAL WHEN FUELED INCORRECTLY AND WHEN THE CTR TANK 1200 LBS SAFETY PROC FUEL WAS ADDED, IT CAUSED A CONTINUOUS EICAS 'FUEL CONFIGN' WARNING.
Narrative: ARRIVED AT ACFT WITH 57400 LBS OF FUEL ON BOARD. MECH WAS XFERRING FUEL TO CTR TANK TO COMPLY WITH CURRENT DIRECTIVES REGARDING CTR TANK FUEL REQUIREMENTS. 1100 LBS OF FUEL WAS XFERRED TO THE CTR TANK. AS IS THE CASE WITH LESS THAN FULL MAIN TANKS, 1 MAIN IS OVERFILLED AND THEN XFERRED TO THE CTR TANK. IT APPEARS THAT THE FUEL WAS XFERRED FROM THE LIGHT TANK TO THE CTR TANK RESULTING IN AN APPROX 2600-2800 LB IMBAL. THIS WAS DISCOVERED AFTER ENG START AND REQUIRED A DELAY OF 12 MINS AT 2200 LBS PER HR FF TO BRING ACFT INTO LIMITS. LESSONS LEARNED ARE THAT FLT IN OLDER B767-200'S WILL BE ACCOMPANIED BY A CONTINUOUS FUEL CONFIGN LIGHT DUE TO FLUCTUATING FUEL GAUGES GOING OVER 1200 LBS. THIS MIGHT PREVENT THE PLT FROM SEEING ANOTHER PROB ASSOCIATED WITH THE FUEL CONFIGN LIGHT.
