I am gearing up to do the center section inspection on my 415C (#2297).
There are two kits offered for this Service Bulletin, SB31, from Skyport: SK-80-1 Smooth belly skin. SK-80-2 Beaded belly skin. My skin is smooth. My understanding is that the holes for the beaded kit are smaller to fit between the beads. My questions: 1) Why not use the kit with the smaller holes? I think one could still do an adequate inspection though a slightly smaller hole. 2) My interior is completely gutted. I think you could see most everything without any holes at all. However, I will put them in for future inspections. I have heard that some of the holes really are not required to see everything? 3) $270 is a lot of money to spend for some plates and re-enforcing rings. If you got a really cool template and the cutting tool, it might be okay, but you do not. Is it possible to source these parts without buying the kit? Thanks to the group. Chris Santa Cruz, CA
