I do hope that you wouldn't
really refer to the AMM for a major structural repair, old chap. Do try looking in the SRM first, then when you've discovered that its beyond the SRM limit, you can contact your FAR21 design office or the manufacturer for an approved repair scheme. If its a Boeing, they will, no doubt, lend you the high blow test equipment and trained operators to do the test for you.
I am simply pointing out that an aircraft fuselage can withstand very much more pressure than the typical Max Diff of around 8.6 psi and it is a fairly routine matter to take it up to 150% of that just to bed it in after initial build or a major repair. For a KC135 fuselage to burst in the fashion shown, it must either have been taken to an almost unbelievable overload value, or else there was existing undetected damage to the structure.
Who do you work for, by the way. I like to be sure of these things when I buy my tickets.
Take care.
