So I'm thinking that this fuel issue has existed from day one of this aircrafts life so that means it's been under reporting the fuel load by 41Tons. So how many times have they landed above the allowable maximum landing weight and were these Heavy landing recorded and inspected?

SQ operated a number of their 777-200ERs in a regional configuration with a deactivated centre fuel tank effectively making them 200As, to do this the pin programming of the FGPU was changed by SQ. My guess is the FGPU from one of these aircraft was swapped onto this 200ER that was being used as an ER. Due to the SQ internal pin programming changes to the FGPU it performanced correctly as a 200A. The part was the correct part for the 200ER, just their poor Mx procedures could not catch the FGPU pin setup was wrong, it is Ann a SQ maintenance cockup, putting the wrong part on, unable to resolve a fuel discrepancy per the AMM.
Thus is what happens when good la engineers make procedures up on the fly not following the AMM and expect the aircraft to fix their mistakes.
The report is a joke, this is a systemic issue with SQs maintenance procedures.
