Dude, can I join Christiaan in requesting more information on that '5000' series numbering; I have never come across it before.
Also, I have asked the CAA surveyor who was most likely to have made that reskinning decision for more data. Perhaps he can remember the problem with the forward fuselage skins. Certainly when we were standing together inside 102 last week and talking about fuselage modifications for relifing the aircraft the problem of Component 30 was not mentioned!
I'll keep you in touch.
