You are going to have to do some additional research yourself. Have you asked NATA? Member "Stoney" on this board is intimately involved with NATA and was AFAIK involved in a recent AD note on the wing attach angles. Are you a member of NATA?
1. Contact Boeing (although I don't know why they would give you this info, it is a liability if they give you this report and you make changes to an aircraft based upon that info. They would get sued first)
2. Contact the FAA (who doesn't maintain a library of stress reports and asks Boeing for help in doing any needed stress analysis)
I don't think that I could get the document from any of the two sources for the reasons that you have indicated.
What exactly is your goal?
I am an aerospace engineer and ex-DER with many years experience in developing and designing major structural repairs, alterations and modifications on a wide variety of aircraft. I would like to develop an approved repair to the attach (bolting) angle that will eliminate the need to remove the wing and replace the whole angle if a damage is detected. To do it right I need original engineering data.
I doubt a fatigue or crack growth analysis was ever performed on T-6 parts during the design phase, so it wouldn't be in the stress reports if that is what you are after.
You'd be amazed to learn the small number of aircraft on which a fatigue or damage tolerance analysis or tests were ever done.
Nobody has a copy of this sitting on their shelf unless someone stole it. It is not public information. It would be contained in a number of a North American Aviation reports. The entire data set may not even exist any longer. Much was thrown out or misplaced.
Yes, I know that. The organization I was with in the 1970s threw away a complete set of drawings and engineering documents of the P-51. I still weep in sorrow… I am still optimistic - maybe in South Africa?
