Here is a link to a Seattle Times report on the original FAA order "debacle"...
Business & Technology | FAA rescinds precautionary order about Boeing's new jets | Seattle Times Newspaper
And a few excerpts by way of summary:
The order applied to the 787 Dreamliner and the new version of the jumbo jet, the 747-8. Brown said the two aircraft should not have been included in a single order.
A new order giving the necessary separation distances for the 747-8 will be issued in the next few days, she said. A new order for the 787 Dreamliner will not be ready for more than a week.
Brown said the order was intended to apply only to Boeing's flight-test airplanes, although that qualification was omitted from the order. Boeing has six Dreamliners and four 747-8s in flight tests.
