Just to comprehend this a bit better - it sounds like the FAA had stripped Boeing of the ability to self-recertify and actually sent inspectors for the most recent certifications. After several successful certifications and what would appear, to the inspectors, to be real process improvements, they're now re-granting Boeing the ability to self-recertify when self-recertification is allowed?

This is well outside my knowledge domain so I'm not trying to make any statements on whether this was correct, but rather to better comprehend the change.
