That's interesting. The trip fuel stated in the factual information that was released regarding the said incident does not seem to take into account the extra fuel burn mentioned in the deferred defects. It's also interesting that the extra fuel burn had been deferred since Nov 2013, some four months before the incident.
yotty: The report only mentions a deferred defect where the right engine was reported as consuming 1.5T more fuel/hour compared to the left engine. There is no DDG reference mentioned in the report. It's hard to say from the information provided whether there was an ACTUAL difference in fuel consumption, or merely an indication problem. One would hope it was the latter given that extra fuel doesn't appear to have been loaded!
