Whether or not test data on, e.g., stability can be withheld from the public as proprietary is not a settled question. I very much doubt that, in the long run, the answer will be that it can. The public interest in that data will very likely be seen by the courts as outweighing any proprietary interest.
And Boeing and the FAA should probably consider that, whatever the data may demonstrate, waiting to divulge it until forced to do so can only magnify the damage to the company and regulator.
