Before I started to drill the pitot/wiring hole in the side skin. I noticed that the hole I made in the F-715 seat rib (using the tooling hole) does not line up with the pilot hole in the F-770 side skin. I did some research on this and looks like I am not the only one who has done this. (Wirejock has done it as well).I decided to use the hole i made in the seat rib as a guide and ignore the pilot hole in the side skin.
