Is this as much the fault of the engine manufacturer as Boeing? Are the engines delivered ready to go and installed by Boeing workers the same way an enine change is conducted at an MRO or are the Boeing boys and girls expected to do full examination of the engine systems before installation?
According to the article's author (though not stated in the link in post #2):
"A source tells me during testing at Boeing in Everett, Washington, mechanics at the plane maker removed the engine's fuel filters and failed to re install them. The planes were then delivered to the airline and began flying in passenger service"
