So what is wrong with the airplane(s) in DXB?
Wiring issues with the fuel sys from what I hear. Some of you guys are blissfully unaware that you are flying around in one of the most avionic advanced passenger aircraft, for an airline that is loathed to train any experienced Avionic engineers. CASA have also had a hand in this by removing the necessity under new law.
So when these wiring (or other complex) defects start to appear on an ageing fleet, the chances of a quick effective rectification and capture become slim. Instead it will just be the standard 'reset carried out', or 'fim proc c/out - nil faults', until the aircraft gets stuck somewhere. Here is a business case in itself to train suitable qualified & experienced staff, but not with this current management team. Going forward we will be increasingly dependant on an overseas MRO with a different operating model to clean up our fleet issues as they become stranded OS.
We just watch it all unfold and think to ourselves "told you so".
One day things will change when a big broom is swept through the place.
