I am going to begin the “swiss cheese” hole cutting in the bottom of the metal wings of my 415C (#2324) project to inspect for corrosion.
I remember some dialog about cutting the holes in the wing or the center section and to be careful not to cut the underlying structure. Looking at SB-29C I see there are also 5 holes in each aileron. I have looked at a few coupes and have some pictures of completed SB-29. None of them have the aileron holes. Any insight from the group would be appreciated. Chris 99674 “Maybe flying this year”
