Narrative:

Lhr is unable to fuel aircraft equipment to release fuel. This causes a great deal of problems and confusion at departure time. Today I had to change the release on flight WWW 4 times at departure time. Flts xx, YYY, and ZZZ also had to be redispatched at departure time due to fueling problems. Several of these flts were on re-releases which only makes the problem worse. Mistakes will be made if this situation is not corrected. The dispatcher and captain should determine the release fuel, not the fueler.

Original NASA ASRS Text

Title: LHR FUELER WAS UNABLE TO LOAD ACFT WITH THE PLANNED FUEL LOAD.

Narrative: LHR IS UNABLE TO FUEL ACFT EQUIP TO RELEASE FUEL. THIS CAUSES A GREAT DEAL OF PROBS AND CONFUSION AT DEP TIME. TODAY I HAD TO CHANGE THE RELEASE ON FLT WWW 4 TIMES AT DEP TIME. FLTS XX, YYY, AND ZZZ ALSO HAD TO BE REDISPATCHED AT DEP TIME DUE TO FUELING PROBS. SEVERAL OF THESE FLTS WERE ON RE-RELEASES WHICH ONLY MAKES THE PROB WORSE. MISTAKES WILL BE MADE IF THIS SIT IS NOT CORRECTED. THE DISPATCHER AND CAPT SHOULD DETERMINE THE RELEASE FUEL, NOT THE FUELER.
