Regarding the Asiana B777 at San Francisco, the report also stated that the Autopilot controls had too many options and the FAA called on Boeing to design simpler Flight Control Units in the future.
However back to this thread, Boeing has "got away with it" ever since the FAA allowed self inspection of assembly etc. With the FAA just turning up and going through their "checklist" to ensure all was in accordance with the Regs.The best way forward in order to try to prevent this happening again would be for the FAA to be properly funded and manned accordingly to do the proper job it is meant to be doing!
