2nd IFSD in 4 months. Previuos one diverted to Syd en-route to BNE from MEL. Both incidents occurring few sectors after engine fuel pump/hmu changes in Syd. No special little fuel leak light but fuel imbalance warning alerting pilots.
Have seen the engine photos and where the leak was from on the first IFSD incident. Caused by an over torque of some bolts on a fuel line. Early reports from the second incident pointing to the same issue of over torque on bolts.
Investigation will shed more light on the incident. Does highlight though the incompetence of some engineering personel, not following published procedures!
