Boeing will cut out the skin damaged by the fire probably in a rectangular cut with rounded edges, he said.
It will cut the patch to the same size and shape and drop it into the space as a plug. The tiny gap around the patch will be filled with paintable sealant that will stretch and compress as the fuselage is pressurized and unpressurized.
Hopefully not!
It would be much more reasonable to cut skin damaged by the fire probably in a rectangular cut and scarfen the edges, then to cut out the patch several inches larger than the hole, scarfen the edges and bond it in place with an epoxy resin which will transfer the loads as the fuselage is pressurized and unpressurized...
because otherwise indeed
Boeing’s repair is going to be pushing the limits of what’s been done in the past
