I think now we have 4 reports of aileron flutter and the pics we have show the aileron dislodged from the hinge and the only part of the hinge that pulled away from the pin and separated was at the outboard section and that section has I believe 6 rivets close together. No one has answered the question as to where the aileron was in conjunction to the wings. I am with Andy and think flutter is the smoking gun. And I would be willing to bet the farm that most do not use a tensi o meter to tighten the cables correctly. I have never looked in the plans but I don't think (and I might be wrong) that the proper tension is listed anywhere. I go by the book as far as cable size tension so if it's there I just haven't seen it. BTW who's airplane is being used for these tests? Are you simply using the plans? It would seem to me a retest of the wings is in order but who is willing to sacrifice their wings and center section for this test. I agree with the other persons post that a inspection of the wrecks is a much better way of finding answers but that would mean you would have to wait and most want answers now but I don't think anything fruitful will come of this other than something is being done right now.

Jeff,
In my HD Construction Manual on page 29 the cable tension is given as "30 to 40 lbs." You can also find what other builders are using in the archives. There is no dearth of information available on the designer specified or builder recommended cable tension values.
