Are we seeing n slight increase in small niggles now that some maintenance are being done in Dubai ?
This aircraft is maintained differently to other types. It has some of the most advanced Avionics systems in the passenger airline industry being maintained by greasers. Yes, the airlines and regulators have decided that the Avionics engineer is not required on this new game changer (good thing it was only a pack problem, reportedly). There are a very small number of them somewhere, but most transits don't involve them anymore.
