All three of Qantas’ new A380 super jumbo jets are up, up and away once more after being grounded for 24 hours to deal with fuel tank and steering problems, the carrier said. The aircraft were grounded in London and Sydney to deal with issues the airline described as “teething problems”. Two were out of service due to a fuel tank indication system problem and one experienced a nose wheel ground steering issue and an unrelated fuel leak issue, Qantas said in a statement. All the issues have been resolved, it added.
