Drilling Holes for Nutplates

After a much needed vacation and ordering parts from Aircraft Spruce we were able to do a little on the airplane again.  The Wingtips were removed and the holes previously drilled for screws were used to locate the two mounting holes for each nutplate.  The actual nutplates were used as drill guides.  The nutplates were cleco's to the rib through the center hole, and the mounting holes in the rib were drilled through the nutplate mounting holes for a precise location.  There are 25 nutplates to be installed in each wingtip area.  Time: 1 hour.
