If the aircraft had been certificated on the basis of additional strength and higher manufacturing tolerances predicated upon the use of high precision CNC machines then such certification should have been rescinded when it became clear that the machines were not being used or were being used in non-conforming or non-calibrated states. The latter issue would have been shown up immediately when items (or even one item) in batches of parts were found to be non-conforming in shape or design because the the CNC machine process should always deliver parts to specification. That this was not happening should have been a red flag to Boeing before any such part was fitted to an aircraft and the FAA should have been aware of this as well. The fact that such parts were being delivered, and fitted, after a fact finding mission to the supplier, where it became clear that the parts were effectively being manually machined (or mangled) is a scandal.Boac wrote: ↑Sun Mar 15, 2020 8:05 pmDo you mean this one - - currently 'not available' I believe in the USA in its original broadcast form - not sure about the YouTube one - don't want to frighten the horses. Interesting that Al Jazeera (English) have so much 'against' Boeing.
Not sure about the 'veracity' of the content, but I'm very glad I am not having to operate the NG in turbulence any more.
This story has an air of verisimilitude or, most likely, the truth about it and points to a huge engineering ethical and management failure at Boeing, the FAA and the rogue supplier(s).
