767 may, of course, have different structural geometry - tdracer would probably know.
Sorry, but my expertise is in propulsion/engines - I'm not very knowledgeable about the structural aspects or details of how the flight controls work.
Pretty much all I can add in that respect is that I was on the Boeing Safety Review Board (SRB) for many years - in the aftermath of the Alaska MD-80 jackscrew crash Boeing did a study to determine if any of the Boeing models had a similar susceptibility and determined that the Boeing designs were still safe. But I don't recall any meaningful details.
BTW voyageur9 - I have worked with the NTSB on several occasions and have the highest respect for the people I worked with. Yes, they do tend to get information and reports out quickly - especially when things are reasonably clear cut. Just saying that the NTSB releasing information to the public is not a priority unless they believe there is some safety aspect that should be quickly addressed.
