Narrative: Requested 131;000 lbs of fuel at departure. Speaking with fueler; Name 1; and myself all agreed to put 40;000 lbs of fuel in the #3 fuel tank. I was in the flight deck while #3 fuel tank was being fueled. Once the fueler was done fueling the #3 fuel tank Name 1 verified the fuel added by verifying the fuel sticks #6 and #7 in fuel tank #3. We then entered the fuel stick numbers into the fuel stick calculator where we determined the total fuel added to tank #3. We got approximately 36;600 lbs of fuel. We then went to the maintenance office and consulted with our lead. We had determined that the fueler had shorted us on the fuel load for fuel tank #3. We then called to have an additional 3;000 lbs of fuel added to fuel tank #3. Once the additional fuel was added to fuel tank #3 we verified this on stick #6 multiple times by both Name 1 and myself. Stick #7 had already been checked and was indicating full. We verified stick #6 and it too indicated the correct calculated fuel for fuel tank #3. We used the fuel calculator to verify again that we had the correct fuel in tank #3 with 40;000/lbs. Once this was all done we discussed with the flight crew the error that occurred with the first fuel load and the addition 3;000 lbs added to fuel tank #3 to give us a total of 40;000 lbs of fuel for fuel tank #3. They were content with this and after deicing the aircraft we pushed them off the gate. Once the aircraft departed; I gave the log sheet to my lead Name 2 to enter into workbench. He had entered it as was written. During the last fuel upload to tank #3 I made a correction to the log page indicating the new stick indications for sticks 6 and 7 giving us a total fuel load in tank # 3 of 40;000 lbs. I forgot to correct this new total fuel on the log sheet. However; the stick indications showed that the correct fuel was in tank #3. The engine flameout I feel needs to be investigate further to determine if there was something that we could have done to prevent this.


Second narrative: During transit of Aircraft X through ZZZ it had a fuel MEL for #3 tank that requires us to fuel by stick.  The two AMT's (Aircraft Maintenance Technicians) assigned to it were Name 3 and Name 1.  I asked them to transfer the fuel out of #3 tank so that they were able to fuel #3 tank using the fuelers receipt and then verify that the fuel is correct with the sticks.  After they had fueled the aircraft they brought the fuel slips and their tank readings into the lead office.  At that time they calculated what they put onboard and showed me the stick readings they had; after putting the information into the stick calculator we found that #3 tank was at 36;491 lbs; so at that time I asked them to add more fuel bringing the #3 fuel tank to 40;000 lbs to match the #1 tank.  We then called for the fueler to return to aircraft to bring the #3 tank to the correct level.  After that the only information I have is what the times for fuel completion and off aircraft.  After the airplane left I was asked to enter the log pages for the aircraft which I did.   After I had checked into the log page that I entered for Name 3 I had missed entering the lbs added which was actually incorrect but wasn't changed on the log page only the sticks were changed and initialed.  The log page stated that the total uplift to #3 engine was 36;491 which I missed when entering.  If you calculate per the corrected stick and inch the total is actually 39;904 lbs; these figures are per the fuel calculator supplied by Company. Need to be more careful entering log pages and double check for accurate imputing.


Synopsis: During flight; an engine flameout caused a diversion to an expedited landing caused by improper fueling with an MEL for inoperative fuel tank quantity system.
