When I wrote that NTSB would look into the certification process, it is indeed implicit that the investigation will be aimed at FAA. One of the slides shows three pages of the (U.S.) Federal Register describing the tests on the batteries. You seem to imply that those tests were largely drafted by Boeing and insufficiently controlled by FAA.RoMax wrote:Not to say you left it out on purpose, but it's important to tell that the NTSB said they will also look at the FAA's part in this story (after all, they are the ones who approved the tests performed by Boeing).
That's probably one cause of the incidents. Looking back at Hersman's speech, I noted these sentences: "a review is needed of the 'special conditions' under which FAA approved Boeing's use of this particular battery technology on the 787. (...) This investigation has demonstrated that a short-circuit in a single cell can propagate to adjacent cells and result in smoke and fire. The assumptions used to certify the battery must be reconsidered", she said.
However, there is still no clue about what caused the the short-circuit in cell #6. Therefore, I'm not sure that the remedies proposed by Boeing will be sufficient to allow the 787 to fly again soon.
And this LOT 787 (SP-LRA) will remained blocked at Chicago O'Hare for an unspecified time (a superb picture which I cannot resist to publish): http://airteamimages.com/boeing-787-8-d ... large.html
