Ah, I see, thanks. So the FAA cut corners when certifying?
I guess trust only works when the other agency is up to the same standards as you, but then "certified by the FAA and the EASA" only really means "certified by one of the two".
No, the FAA didn't cut corners, Boeing did. The FAA did a bad job catching it.
And being certified by both means that orgs and aircraft are certified by both. Decades of cooperation and alignment of regulations and requirements mean that the sevond certification is covering the delta between both, believing the common stuff to be properly cerified by the other regulator. That is where the FAA lost trust.
Hence my believe the FAA will not show much liniency to Boeing this time.
