Engine.
Not made by Boeing.
Maintenance.
Done by United Airlines.
But go ahead ... follow the crowd ... don’t use your brain.
I don’t get the near religious devotion people have to Boeing on this website. Why can’t you acknowledge some room for accountability, and that many a great American company has suffered similar declines in recent decades?
I am pretty sure engine maintenance is done by the engine manufacturer. As I understand it, the engines are sold for a song, the real cost and revenue for the mfg is in maintenance.
Exactly...not Boeing’s fault
