I may have asked this question before, but to what extent can an airframer, ie Boeing, modify an existing type, via improvements, within the scope of a current type certificate?
Example, I just read an article that mentioned that the 737NGs rolling off of the assembly line today are much better performers than when the type was initially introduced. I know that they put new wing fairings on updated versions of 747s, and I know they make continuous improvements aerodynamic improvements on the 737 series.
I've also seem pictures of Gulfstream GIIs with different nose-cone profiles.
So to what extent, and on what structures, can the manufacturer make modifications under the current Type Cert?
Thank you in advance.
