The problem is quite serious for what I hear, word on the street has it that it landed off a training flight when the two engines with trust rev would not cancel so the shut them down, started the APU on taxi in then at the gate shut the other two engine down, instead of the APU picking up the elect load it all went rather dark and quiet.
Engineers then found one of the boxes in the E&E bay happily burning away.
Unable to fly it stays here for repair.
Great start for the ugly bus:
