Though a bit of digging around suggests that when the aircraft in question was flying for CityJet it was certificated at 42,184 kg (93,000 lb).
So unless it had the higher-weight (97,000 lb) mods embodied subsequently, the lower weights would presumably still apply.
Having said that, I haven't seen any suggestion that the aircraft departed with less than full tanks - the loadsheet would make interesting reading.
