Ah, what exactly do you mean in respect of "....Each built of entirely different spec metals........' ?
We can start with skins/frames/stringers at aluminium alloy right ? Very likely to be based upon the QQ-A-XXX (or its predecessor) family of aluminium alloys, yes ? While manufacturers often put their own specification over the top of these generic specifications (Federal Specification in this case), what is so 'entirely different' between the material specs between these two aircraft types?
