Brief Description: Finish all Nutplate Countersinks-Flanges
Once all of the nutplates for the access panels were riveted to the bottom flanges, a #40 pilot countersink bit was used to countersink the holes for the #6 screws using the nutplates as the jigs. All of the countersinking along all of the flanges is now complete and all of the nutplates are riveted in place.
