Rich finally talked me into having access panels in the Tailcone Fwd Top Skin to allow access to the air-conditioner in the future. AirWard has a nice kit with two panels. One for each side. I did make one change. The nutplates supplied with the kit were MS21047L08 (K1000-08) and I substituted K1100-08's that allow space for a dimple in the skin. I plan to run a bead of Pro Seal around the doubler plate to help with water ingress. I did check the cost of a new skin before I made the first cut. The cutting went fairly well. I started with a nibler that attached to my drill motor, then a cutoff wheel on a pneumatic grinder and finally a 5 inch sander and a drum sanding wheel for the inside radius of the corners to give a nice finished edge. I also left a 1/16th inch paint gap around the edges.
