[QUOTE]This led to each airframe being 'individual', almost bespoke and required that standard components were having to be tailored and modified to permit installation. (A case of having a jet-pipe manually adjusted with a hammer to enable its fitment and an issue of cabin floor beam location comes to mind).[QUOTE]
Another example, allegedly when the first MRA4 conversion was under way the new wing box did not quite match the fuselage. Measurements carried out across the fleet identified that the delta between the longest and shortest airframe was in the region of 18 inches! In those day aircraft were "coach built" by craftsmen forming pieces of metal, nowadays they are a kit of parts, and with modern manufacturing techniques every one of a particular part is exactly the same size!
