Think Boeing has it bad?

Boeing's 787 was only grounded for a couple of months and looks like it will fly again by the end of this month.  Bad, but read this.
Eurocopter EC225's (a big helicopter used to support North Sea oil drilling) was grounded in October of 2012 and looks to stay grounded until this fall.  Grounding was ordered by both the British and the Norwegian governments after two forced landings in the North Sea, caused by failures in the main gear box.  The main gearbox connects the engines to the rotor.  When that breaks the rotor stops turning and the chopper falls out of the sky.
  That's a lot worse than flaming lithium batteries.
